SQL 2012 :: Setup A Client Alias To Connect To A Named Instance On Another Server?

Jul 23, 2014

I am trying to setup a client alias to connect to a named instance on another server.

TITLE: Connect to Server
------------------------------
Cannot connect to fred.
------------------------------

ADDITIONAL INFORMATION:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

I have set up the alias on the server and as expected it works. On the client side I have used the SQL Server Client Network Utility to configure the client side alias but no luck

I am using TCP/IP with a specific port ..

By the way the SQL is SQL Server 2012 Ent and the O/S is Windows 2012 R2 minshell

SQL 2012 :: Clustered SSAS Unable To Connect To Named Instance (instance Not Found On Server)

Mar 20, 2014

I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.

I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.

I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.

Should I be able to connect as serverinstances for a named clustered instance in 2012 ?

SQL 2012 :: Named Instance With Specific IP / Port And Connect Using Browser

Jul 31, 2014

I'm trying to configure a named instances of SQL Server 2012 SP2 to have specific IP addresses and listen to that IP on port 1433. Alongside this, I have the default instance running on a different IP and listening to that on port 1433.I've managed to get them configured so that they are reachable using the IP, and looking at the log for each they are listening correctly on that IP on port 1433; in addition, the default instance connects fine using the SERVERNAME.However, when I try and connect to the named instance using the SERVERNAME/INSTANCENAME syntax, I receive the following:-

"Cannot connect to SERVERINSTANCE.
Instance failure. (System.Data)"

Configuration for the TCP/IP protocol for that instance is as follows:-

Protocol Tab

Enabled= Yes
Keep Alive = 30000
Listen All = No

IP addresses Tab

IP1
Active = Yes
Enabled = Yes
IP Address = 10.1.1.1
TCP Dynamic Ports = 0
TCP Port = 1433

[code]...

The SQL Browser service is running and prior to switching off Listen To All, I could connect to the instance remotely using the instance name.

Alias For SQL 2000 Named Instance

Aug 12, 2002

We have a two node activepassive SQL Server 2000 cluster SP2 running on Window 2000 advanced server SP2. Everything is working fine including failover. Today we migrated over our 7.0 databases to the SQL cluster and they attached fine and upgraded fine but we would like to shutdown the 7.0 server and bring up the clustered SQL Server under the old name. We will be running 3 instances of SQL Server 2000 on the Cluster so at least 2 of these will be named instances like this: "Virtual serverinstance". Is it possible to create an alias for this SQL Server so that we could access the server under the original name of the server???
Thanks!!!

DB Engine :: Cannot Connect To Remote Named Instance Of Server

May 8, 2013

We have 3x instances of SQL Server 2012 installed on a single remote server - there's the default MSSQLSERVER instance, then INSTANCE01 and INSTANCE02. I can remotely connect to the default MSSQLSERVER instance through SSMS, but I cannot connect to either of the additional named instances (INSTANCE01 or INSTANCE02). 

For example, if I try to connect to "sql.domain.com", I can successfully access the default instance on the remote server. If I try to connect to "sql.domain.comINSTANCE01", I get an error stating

"A network-related or instance-specific error occurred while establishing a connection to SQL Server".

However - if I try to connect to "sql.domain.comINSTANCE01, 49301" (where 49301 is the TCP Port for the TCP/IP Protocol for this SQL Server instance), I am able to successfully connect.

This leads me to think that there's a communication issue with the SQL Server Browser service running on the remote SQL Server and my workstation. 

The following items have been verified:

SQL Server Browser is running on the remote SQL ServerWindows Firewall has been disabled on the SQL ServerTCP Ports 1433, 1434, 1954, and 49301 have been opened up on the remote destination's firewallUDP Port 1434 has been opened up on the remote destination's firewall.

Cannot Connect To A Named Instance Of SQL Server From Compact Framework 2.0

Mar 14, 2008

I have two instances of SQL Server on the same PC:

Default instance: SQL Server 2000
Named instance with name MS2005?: SQL Server 2005.
Also I have another SQL Server 2005 on another PC.

I created a .NET 2.0 Compact Framework application that connects to the database and executes simple query. This application can connect to any instance of the SQL Server when it is executed on the PC (not on the server). But the problem is that when I try to execute the application from the windows CE 5.0 device, the application can only connect to the default instance (SQL 2000 and 2005) and can not connect to the named instance (Name: MS2005).
Is it some kind of limitation of the SqlClient library for the compact framework?

Below are the code and connection strings:

string connectionString = Server=1.1.1.1;Database=DB1;Uid=sa;Pwd=?
string connectionString = Server=1.1.1.1\MS2005;Database=DB1;Uid=sa;Pwd=?

using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open(); //This is the point where exception is generated

using (SqlCommand command = connection.CreateCommand())
{
command.CommandText = "select count(*) from users";
object result = command.ExecuteScalar();

Console.WriteLine("Result: [{0}]", result);
}

connection.Close();
}


Thank you for your time and advice.

SQL 2012 :: Could Not Connect To Server Using Alias

Feb 17, 2015

I had two servers, in which SQL Servers are installed. I created a alias for server

Server 1 : test1.sqlcloud.com (Alias name with port no other than 1433)
Server 2 : test2.sqlcloud.com (Alias name with port no other than 1433)

I can connect to the servers using the port. for ex server1 to server2 and viceversa using "test2.sqlcloud.com,port". But I could not connect to the server by only specifying the alias name ("test2.sqlcloud.com"). When I am connecting I am getting the following error.

"TITLE: Connect to Server
------------------------------

Cannot connect to test2.sqlcloud.com.

ADDITIONAL INFORMATION:

Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time.

Problem Using Client Tools To Remotely Connect To A SQL Server Instance On Another PC

Jan 18, 2005

Someone please help me before I loose all of my hair :mad: !!!

I have two machines, a Windows Server 2003 machine running an SQL Server Standard Edition database instance and client tools (Enterprize Manager etc.), and a workstation PC running Windows XP SP2 which has just the SQL Server client tools (not an actual DB instance).

I'm trying to use the Enterprize Manager client tool on my WinXP machine to remotely connect to the server instance on the server PC (via 'New SQL Server Registration' option). Everytime I do this I get the following error message:

Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server Connection.

Now I've tried using different usernames and passwords. I have login details for my SQL Server set to use Windows Login rather then SQL Server login, so I tried remotely connecting with the username and password for the server PC, tried 'sa' with server password, even tried setting up a new user on the server and logging in from the client with that, no luck. I've opened up correct ports 1433 on both PCs, even disabled the windows firewalls algother. Both server and client have SP3a installed, WinServer2003 has SP1 and XP SP2.

So I'm at a loss to how to remotely connect to my SQL Server. FYI I know the server itself is working fine because I can connect to it using Enterprize Manager/Query Analyser on the local machine. Any ideas? Many thanks for your help!

SQL Server 2012 :: Remove Named Instance From Failover Cluster

Oct 13, 2014

In QA we have a two-node cluster with four instances of sql. In trying to add a fifth, I was given an IP address already in use so the install hung.

I removed it from the cluster but it is still there in the registry etc on the node I was working on.

I read about using the maintenance tab of the sql server install to "remove a node" but the terminology is confusing. To me a node is a physical server and an instance is an instance of sql server -- not the same at all but they are often referred to as the same thing.

I definitely don't want to remove one of the servers from the cluster.

Problem Connecting To SS2K5 Named Instance Using Client Tools

Aug 9, 2007

Hi,

The problem I have is this:


I have installed SQL Server 2005 Enterprise Edition on a W2K3 server that already has a SQL Server 2000 default instance installed. The installation appears to be a success. The problem is that having installed the client tools, and trying to connect, I get the following error message in a dialog:


"Cannot connect server SERVERNAMEINSTANCENAME
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating
Server/Instance Specified)(Microsoft SQL Server)"


The funny thing is that I can connect to the SQL Server 2000 default instance that is on that server.
So it's obviously not a connection problem per se at my end i.e. bad dns etc which might stop me resolving the server name.


Googling for this error text gives the following advice on various web sites:


1. Check that the remote server allows connections.


It does, as other colleagues in my team have successfully installed the tools and can connect with no problems.


2. Check that the SQL Browser service is running.


It is, as without this running, my colleagues would not be able to connect either.


3. Open SQL Server Configuration Manager. Select "SQL Server 2005 Network Configuration | Protocols for MSSQLSERVER" then enable the protocols you need.


The required protocol (TCP/IP) is enabled. Named pipes is also enabled, although I don't think that we're using that. And shared memory is also enabled by default.


4. Open the firewall and add exceptions for sqlbrowser.exe or UDP port
1434


There is no firewall running at either end of the connection and as mentioned I can connect to the SS2K default instance.


5. Make sure that the server machine is reachable.



I can connect to the SS2K default instance so it must be reachable. I can't see that I would need to change any configuration settings as my colleagues are using exactly the same default settings for their connections and they work fine.


The only thing that I have done differently is that I originally installed the client tools using someone else's privileged account as I didn't have admin rights on my box. The client tools didn't work, so I got admin rights to my box, uninstalled the client tools and then reinstalled them using my account. Still no luck. Not sure if something is still hanging around after the uninstallation that would cause me a problem.

To help, I've also filled out the following questionnaire:

[1] Client side:
> What is the connection string in you app or DSN?
There isn't one. I'm trying to connect from the SQL Server Management Studio | 'Connect to Server' dialog.
> If client fails to connect, what is the client error messages?

2005, this failure may be caused by the fact that under the default settings SQL Server does not
allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating
Server/Instance Specified)(Microsoft SQL Server)"
Is the client remote or local to the SQL server machine? Remote
Can you ping your server? YES
Can you telnet to your SQL Server? YES
What is your client database provider? [SNAC | MDAC | ADO.NET1.0 | ADO.NET2.0| other (please specify] N/A

What is the SKU of MS SQL? Enterprise
What is the SQL Server Protocol enabled? [Shared Memory | TCPIP | Named Pipes ]. All 3
Does the server start successfully? YES. Other people can connect to the same instance.
If SQL Server is a named instance, is the SQL browser enabled? YES
What is the account that the SQL Server is running under? Domain Account
Do you make firewall exception for your SQL server TCP port if you want connect remotely through TCP provider? N/A. Firewall not running.
Do you make firewall exception for SQL Browser UDP port 1434? N/A. Firewall not running.
What tool or Application are you using to connect to SQL Server SQL Server Management Studio

[3] Platform:
What is the OS version? Windows 2003 (Server side), Windows XP Pro Version 2002 SP 2
Do you have third party antivirus, anti-spareware software installed? Symantec AntiVirus

[4] Misc:

Setup And Upgrade :: Determine What Port Does Named Instance Are Listening?

Sep 22, 2015

I have a named sql instance on SQL 2012. The issue is that the clients is having problem connecting to it when the firewall is on, this is not consistent. The connection is fine when I disabled the firewall. When I turned the Windows firewall back on, it will work for awhile and it fails. I checked the SQL configuration manager and saw that a dynamic port is assigned to the named instance. I did put that in the firewall rule and unblock it. I also put TCP 1433 and 1434 as well as the browser service port, TCPUDP 2382 and it still didn't work.What is the best way to determine what port does the named instance are listening?

Hi,

I have two domains setup with two way trust in place. SQL server 2005 is installed in domain A.

Is it possible to log in to SQL server using machine account of a machine in domain B?

I have been told that you cannot access SQL server from another domain using machine account. But I cannot find any resource or references about it.

If this isn't the right MSDN forum for this I apologize, but any advice would be greatly appreciated.

Thanks in advance.

Cannot Connect To A Named Instance Of SQL 2000 Or 2005

Jan 20, 2006

Hi,
I am struggling connection to a named instance of SQL 2000 (SP4) from another machine but without any success. I get an error message saying that the server does not exist or access is denied.
 
The security configuration in this named instance is the same as the default instance (also 2000) and the remote machine can connect to it successfully.
 
I also configured the aliases in Client Network Utility in the client machine and set the server (machine) name and the port number used by the instance - but no help.
 
I use osql and Query Analyzer to connect to it, but I cannot connect by any of them.
 
Connecting locally, in the machine where the instance is installed, is successful.
 
The same behaviour appears when I try to connect to another instance on the machine which is 2005.
Something with the named instance is problematic.
 
Any help?

Cannot Connect To Named Instance Of MSDE Through Enterprise Mananger...

Jan 2, 2006

Hi- I am hoping someone can help me or shed some light on an issue I am having.
I have recently moved to a dedicated server with MSDE installed on it. The server was installed as the default instance and I changed the password to the SA account. I then copied my entire SA database over to the new MSDE database and everything was working good so it seemed. I believe at some point during copying of the data, or after installalling an application the SA account begain to fail and the password was changed. I have no idea how this happened, and better yet when I tried to change it logged in as the administrator with OSQL it told me I did not have sysadmin rights (I tried multiple Windows NT Auth logins and still got this error trying to change the password).
So... I reinstalled MSDE and created a named instane. I then attached the mdf/ldf files to my named instance and am able to connect ok from a .NET application directly to my new MSDE Named Instance database. Sounds like everything is great right? Not really, I can't figure out how to connect through enterprise manager and its driving me CRAZY!
1. I CAN connect via any .NET app and a connection string
2. I CAN connect via the server with OSQL
3. I CAN connect via the web based enterprise manager (which is very limited and a freeware ASP app).
4. I CANNOT connect via enterprise manager. I have verified from the (SVRNETCN.EXE utility)  that the port is open and have tried connecting to MY_IPADDRESSNAMEDINSTANCE but no luck. 
One additional side note, when I wasn't using a named instance I had no problems connecting through enterprise manager to my default MSDE instance.
Any help would be grealy appriciated, this is driving me nuts!
-Chad

Connection String For Default Instance Of SQL Server 2005, On A Box Also Running A Named Instance Of SQL Server 2000

Nov 15, 2007

The box I am trying to connect to is running two instances of SQL Server.
There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'.
 I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" />
However,  I am having trouble connecting to the Default SQL Server 2005 instance. I have tried:
<add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" />
 but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used:
<add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" />
but this doesn't work either.
 
Am I mssing something here? Any help much appreciated
Thanks...

Setup And Upgrade :: Activity Monitor Shuts Down If Connect To Instance Its Monitoring With Performance Monitor

Aug 19, 2015

If I'm on a remote machine, meaning a computer not in the WSFC cluster, and I open SSMS 2014, point it to a SQL Instance, and open activity monitor:

1.  I get all the panes and charts except % Processor Time.

2.  Then, if I authenticate to the cluster's domain by mapping a drive with valid domain credentials, I'm free to put performance counters in the Perfmon - - - but SQL Activity Monitor shuts down with“The Activity Monitor is unable to execute queries against server SQL-V01INSTANCE1..Activity monitor for this instance will be placed into a paused state.Use the context menu in the overview pane to resume the activity monitor.

Additional information:  Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))(Mscorlib)”

3.  Of course, the Activity monitor can't be resumed via the context menu. Removing counters and closing the perfmon do not work.  I dropped the mapped drive and rebooted the machine.  That brought back 95% of the information in the Activity monitor.

4.  Further experimentation showed that any mapping of drive shares present on the SQL Server to the computer running SSMS cut off functionality of the 'overview' pane in the remote machine's SQL Activity monitor -- the monitor that had been trying to watch the server offering the shares.

How Can I Get The Port Of A Named Instance Of SQL Server

Sep 14, 2004

Thanks for Microsoft's Windows XP Service Pack 2 and Windows Server 2003 that make the security much stronger. However, besides the invisible benefit so far, I have become the victim of this security policy.

I have several named instances of SQL 7/2000 installed in my machine. They are not visible out of the Microsoft new fire wall. I need to access the instances from outside the fire wall, but I don't know which port I should open for the instances.

From SQL online, the default instance of SQL server is connected through TCP/IP by default port 1433. I could successful open that port and made the default instance visible to outside. However, the port 1433 doesn't work for the named instances. SQL online said, the port for named instance is dynamically (by default) chosen the first time the instance is started. So, actually, I have no way to know the port.

Is there anyway that I can check the database or somewhere to get the port that is used by the named instance?

Thanks for any input and recommendation.

Connecting To Named Instance Of SQL Server

Jun 16, 2008

We have installed SQL 2000 SP4 on Windows 2000 Server. We created named instances on the SQL server.
When trying to connect to named instances from a remote sql client which is on windows 2000 and windows 2003, its throwing an error message saying that remote connections are disabled.
But, remote connections are enabled on the SQL server.
After changing the component services settings on windows 2003 where sql client is installed, we are able to connect to named instances.
But, after applying the same settings on another windows 2003 machine, we are unable to connect to the same instances.


We have another machine where we installed SQL 2005 on windows 2003 SP1. When trying to connect to named instances from any remote client, its throwing an error message saying that remote connections are disabled. But, remote connections are enabled in SQL server settings. We tried connecting to the instances by changing the component services settings but still we are facing the same issues.


Can you please help me on above issues?

Migrating From SQL2K Named Instance To SQL2K5 Default Instance

Feb 19, 2007

Hi, I have a task in hand to migrate (upgrade) from SQL2K named instance to SQL2K5 default instance. There are many intranet applications touching current SQL2K. I would like to perform this upgrade such that I don't have to touch any application code - meaning I don't have to change the connectionstring to point to new Default instance. How can I achieve this?

So, in otherwords, here is what I want to achieve:

Current Server: SQL2K: SERVER_AINSTANCE_A (named instance)

Upgraded Server: SQL2K5: SERVERB (default instance)

If I have both default, I could achive this by setting up DNS alias after migration done so that any call for SERVER_A would point to SERVER_B. But in my case, I don't have SERVER_A, I have named instance. Is there any solution?

Regards,

Connecting To An SQL Named Pipe Alias

Jul 26, 2007



Hi All , I have been racking my head on this for the last two days and really it should be a no brainier. Anyways I can only assume that Im missing something here but...



In a nut shell I am attempting to connect to a new SQL Alias that i have created by simply adding the following in the client network utility

Current SQL server name DASQL

Default instance



Alias Name: TASQL

Server Name: DASQL

Pipe Name: \DASQLpipesqlquery



I can connect the new alias via the local (server consol) yet when i attempt to connect remotely it times out as if it can't find the server.



Any Thought?

Thanks

Linked Server Named Instance Queries

Feb 23, 2008

I am trying to perform a distributed query however have a situation I haven't dealt with before the linked server I add to do the query is a named instance (DVD_NASDOMINO). How would I specify this in a query as in the FROM part in a sql statement. I tried the obvious DVD_NASDOMINO.qlsdat.dbo.stmenqry and DVD_NAS.DOMINO.qlsdat.dbo.stmenqry.
Both returned errors in the query.

Thanks for the help.

Named Instance Problems (Default Of 7.0/2000 Instance)

Oct 10, 2001

I am trying to set up a Named Instance of SQL 2000 on the same machine that has a default instance of SQL 7.0. The setup always completes and I am able to register the Named Instance of the SQL Server with which it was installed on. However, when I try to connect the users to the database, with both windows and SQL authentication, I receive a SQL server not found error. I have tried an alias setup as well as physically specifying the port number in settup up an ODBC connection.
Has anyone ran into similar problems?
Also, has anyone been able to successfully complete the process as mentioned above?
