SQL Server Does Not Allow Remote Connections. (

Dec 8, 2006

Hi,

Attempting to open a new database engine from a Windows 2003
R2 server (x64) which is

running SQL Server 2005 to my desktop PC (XP Pro) which is running SQL 2005 developer
edition.



I€™ve opened up TCP/IP and named pipes and enabled all protocols
within surface area configuration and server

configuration manager but get this€¦



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: TCP Provider, error: 0
- A connection attempt failed because the connected party did not properly
respond after a period of time, or established connection failed because
connected host has failed to respond.) (Microsoft SQL Server, Error: 10060)



Is this a red-herring type message? I ask because the text
states €œthis failure may be caused€? and as far as I can see I€™ve open up my

PC to all connections.



Thanks in advance



Dave

SQL Server Does Not Allow Remote Connections

Oct 11, 2006


Hello ,

The problem is that we are having Problem while making the remote Connection to the Sql Server 2005

Basically We are having a problem connecting to SQL2005 through a package remotely. when we try to connect to a remote data base, we get the following error

[Connection manager "CRA LRRS Development DB"] Error: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Login timeout expired". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "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.". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. ".


Although by running the configuration manager on the Remote DataBase System we have enable the Remote Connections through name and IP both but still it cant access it.

Please tell us the possible consequences and provide us the feedback.

I will be really obliged if any of you can provide us the feedback on it as soon as possible.

Thanking You,
Yours Sincerely,

SQL Server Does Not Allow Remote Connections

Apr 7, 2008

I am having trouble with Report Manager. It seems that every day or every other day we get this message:

"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: TCP Provider, error: 0 - No such host is known.) 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."

To fix this we open the Surface Area Configuration for the server that hosts the Reporting Database and stop and restart the database engine then open up the Surface Area Configuration for the server that hosts the Report Manger database and stop and restart that database engine along with the Reporting Services Browser.

This actually may not be the exact order that we do the stop/starts because we have tried so many different combinations (ie. stop one then start another then restart that one, etc.). Anyway, we usually keep on stoping and restarting until we can get back into Report Manager without getting the error message from above.

Does anyone have any insight as to what this could be??

SQL Server Does Not Allow Remote Connections

Sep 21, 2006

I downloaded VS studio express, and created a personal website using the wizard to test drive the thing. When I hit ctr + f5 to run the sample provided, then I get this message:

"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) "

I tried disabling the firewall (Norton's firewall because Windows is disable always). Any suggestions? This is a brand-new machine, running XP sp2, just downloaded the VS studio express.

I really appreciate your inputs.

SQL Server Does Not Allow Remote Connections

Dec 18, 2007

I've got the following error from running my aspx webpages, trying to communicate to the MSSQL 2005 database.

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: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server)


I've see and read a lot of chatter on the forum on the topic, but didn't find my solution. I have done a number of things, all of which didn't shake the error.
1) I went into SQL Server Surface Area Configuration for Services and Connections, and set Remote Connections to Local and Remote Connections, using TCP/IP only
2) Disabled Firewall
3) Made exceptions throught the Firewall for SQL Server and SQL Browser


Any other suggestions, thanks in advance.

SQL Server Remote Connections With Web Service

Feb 8, 2007

Hello,
I am getting this error with a web service trying to fill a strongly-typed dataset stored in another project that the web service has connection to.  I keep getting this error:
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) 
I set it to allow TCP/IP only, TCP/IP and Named Pipes, and Named Pipes only remote connections allowed.  But it still doesn't work.  I don't understand what the problem may be.  I stopped and started the database engine service every time (this is a SQL Express database attached to the server, by the way).
Any insight would be helpful, Thanks.

Sql Server Remote Connections Error

Jun 2, 2008

Guys,

I can connect the sql server instance through management studio and I can also create a DSN to the same sql server instance. But when the application tries to establish the connection i get the following error

I have checked the following

SQL BROWSER is started
TCP/IP default port 1434 is enabled

At this point I am not sure how to proceed further to trouble shoot this issue.


System.Exception: 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) ---> System.Data.SqlClient.SqlException: 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.

Any suggestions and inputs would help.

Configure A Server To Allow Remote Connections?

Nov 3, 2007

I already asked this question at the MSDN forums, but I'm asking it here because I got conflicting answers.

I want to configure my server to allow remote connections. For some unknown reason, I'm unable to do this with the Surface Configuration Tool. My understanding is that I can accomplish this using the sp_configure stored procedure. Is this correct? If so, can someone please give me an example of the correct syntax? BTW, I'm running SQL Server 2005 on winxp pro sp2.

Thanks in advance.

Sql Server Remote Connections Fail

Nov 26, 2006

i installed sql server express, but i did not select to use mixed mode (the reason being for this that every time i did i got a install coruption error) i want to be able to connect the database remotly using the sqlservers jdbc driver. however i need a user name and password. therefore to do this i believe i need to be able to acess the database remotly.

ive tried everthing:
1. changing the surface area remote conenctions to allow remote connections using tcp and ip only
2. restarted the database
3. restarted the server
4. restarted the browser
5. checked the tcp/ip settings are enabled.

but when i do the follwing in command line i get this:

C:>osql -E
[SQL Native Client]VIA Provider: The specified module could not be found.
[SQL Native Client]Login timeout expired
[SQL Native Client]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.

which indicates that its still not allowing remote conenctions, any ideas?

Fellow Devs,
I have an instance of SQL Server Express 2005 running on another box and I have Remote Connections enabled over both TCP/IP and Named Pipes, but on my other box I keep getting the error that the server does not accept Remote Connections.
Any ideas why this might be happening? Is there some other configuration?

Help With How To Configure SQL Server 2005 To Allow Remote Connections

Nov 14, 2006

Hi there! I've been trying for several days now to configure SQL Server 2005 to allow remote connections, apparently, with no luck.
I always have this error message: Microsoft SQL Native Client: 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.
I've followed the instructions at this link -> http://support.microsoft.com/?kbid=914277&SD=tech, but I have been having the same problems.
I've already adjusted my firewall settings.
What should I do? 
Please help me...

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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) 
When am running the application from my laptop i am using the external IP and when I publish it in the same server i am changing the IP for the server name. The most interesting part is that the web can read but when it tries to insert is when am getting this error.
Any clue??' I can select, delete, insert using Microsoft SQl Server management Studio from my laptop, then the sql server accept remote connections.
I do not understand why the ASP.Net application works perfectly when runs from my computer but get this error when is publish in the server.

SQL Server 2000 Enable Remote Connections

Oct 4, 2007

Hi guys
Apologies if this is the wrong place to be posting this but I have posted on a few forums and have not had any usable answers to this question, so I am hoping you guys will be able to help me.
I have 2 servers that are on the same domain. My ASP.NET application is running off the first which has .NET 2.0 installed, and I have an SQL Server 2000 db on the other. Whenever I try to connect I get the following error: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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
The connection works when I run the project in VS Development Server on my work computer, but as soon as I upload to the server I get this error.
I have scoured Google but all of the sites I come across are for SQL Server 2005 and are just not suitable for solving the issue on 2000.
Any help would be greatly appreciated as I cannot continue my current project until this issue is resolved.

Default Settings SQL Server Does Not Allow Remote Connections

Apr 16, 2008

 
Please help a teacher at wit's end. 
I have created a site using Microsoft Expression Web.  The site includes a create user page on which I placed the create user control (wizard), and a login page (which houses a login control) .  When the site sits on my local host all works well and I render the pages on my browser locally: the first time a user is created the aspnetdb.mdf file is automatically created into my app_data folder, the new user information is saved and can be accessed on the login page etc.  However,  when I upload to my hosting server. (godaddy) I can navigate to each of these pages seamlessly but when I try to use the controls on either page I get similar errors:
 
Exception Details: System.Data.SqlClient.SqlException: 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)
I am not a programmer, and am just beginning to learn asp.net.  However, I need to solve this problem.  GoDaddy cannot help me, they say, because this is inside of EW and that is a MS problem.  They have on the several ocassions I have contacted them, suggested compatibility issues (since they use SQL server 2003 and 2008 not 2005, or suggest that I need to script something to ensure that the .mdf file is recognized by their server, or that it was a database problem and that I may need a database programmer. They did tell me that it is important to note that the databases are hosted outside their server. I have not found anything in the EW side of this equation since most forums and support etc, deal more with the design part, than the online publishing part.  I have tried to find a programmer locally that could help me, and have yet to find one.  I am so close to being able to publish a site that meets our small school's needs, but cannot jump this one hurdle.  Can anyone tell me what I can do?
Any help will be appreciated.

Installing SQL Server Express && Remote Connections On XP Home

Jul 6, 2006

My target market includes Micro-SMEs (i.e. 1 to 2 person business). This users often have multiple computers, but tend to run XP Home edition. Hence I need to set up a SQL Server Express on one of the machines and allow the other machines to access it.

So far I realise:

XP machines must be SP2ed (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=379560&SiteID=1)
XP Home machines need to be in the same work group (am I right?)
I have to Open up the MS Firewall on each of the machines for TCP ports 1433 and 1434 (see http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=511441&SiteID=1)
On the machine hosting the SQL Server Express instance, start the "Browser" Service (again http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=511441&SiteID=1)

I have several questions surrounding this.....

If I package SQL Express with my application is there away I can get the Browser to be started automatically? Do I need to write some custom code using the Microsoft.SqlServer.Management namespace?
My understanding of the SQL Server security model is that ideally I should ideally use Windows Authenticated users connections - how do I set up the remote XP Home user on the XP Home machine which is hosting the SQL Server Instance? I'm thing I may have to used Mixed Mode and pass the SQL Server username and password in the connection string. Am I right or can I use Windows Authenticated?
Are there any more resources other than http://msdn.microsoft.com/sql/express/default.aspx?pull=/library/en-us/dnsse/html/emsqlexcustapp.asp which I should look at for help on installing an app bound to SQL Server Express?

Thanks in advance

How To Allow Remote Connections To SQL Server 2005 Express Database

Feb 27, 2006

I've developed an asp.net 2.0 web app with vs 2005 and am using a SQL Server 2005 Express database. The app works fine locally, but after uploading to the remote web server the following error occures:
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)

How do I go about granting remote connections to SQL Server Express?

Does the web server have to have SQL Server Express installed in order to run apps that utilize SQL Server 2005 Express databases?

Do I grant access locally on my machine or do I have to be on the web server to grant remote connections?

I've been using .net 1.1 with access databases for the past couple of years, so this is all new to me.

Thanks.

Cannot Configure SQL Server Express 2005 For Remote Connections

Aug 15, 2006

Hello. I have SQLEXPRESS 2005 installed on my laptop running Windows XP Home Edition with SP2. I have an application that can connect to the local instance with no problem. The other day, I tried to configure SQLEXPRESS 2005 for a remote connection from my desktop. To date, I have been unable to figure out how to do this.

I have followed the instructions posted at various locations on the internet, but to no avail. While I can configure SQLEXPRESS 2005 to allow TCP/IP connections, I have been unable to restart the server.

Here is the pertinent snippet from the error log:

<time> Server A self-generated certificate was successfully loaded for encryption.
<time> Server Error: 26024, Severity: 16, State: 1.
2006-08-14 21:02:27.18 Server Server failed to listen on 'any' <ipv4> 0. Error: 0x277a. To proceed, notify your system administrator.
<time> Server Error: 17182, Severity: 16, State: 1.
<time> Server TDSSNIClient initialization failed with error 0x277a, status code 0xa.
<time> Server Error: 17182, Severity: 16, State: 1.
<time> Server TDSSNIClient initialization failed with error 0x277a, status code 0x1.
<time> Server Error: 17826, Severity: 18, State: 3.
<time> Server Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log.
<time> Server Error: 17120, Severity: 16, State: 1.
<time> Server SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.

I have a feeling this problem is due to the way my system is configured, not necessarily how my SQLEXPRESS 2005 is configured. My laptop and desktop are connected via a wireless router, and both machines are running Norton Anti-Virus 2006. I've added sqlserver.exe and sqlbrowser.exe to the exceptions list for the Worm protection on the laptop, i.e., the server machine. There's not a setting at the router that would prevent the server from re-starting, is there?

Any help is GREATLY appreciated!

SQL Server 2005 Rejects Remote Internet Connections

Sep 27, 2007

PROBLEM:


SQL 2005 rejects connection from an ASP.net test webpage (shown below).

CONFIGURATION:

Internet > Concast Cable > Router > Sever01 Nic1 > Server01 SBS 2003 & SQL 2005 > Sever01 Nic2 > Switch > Local Area

Linksys Router WRV54G( Firmware Version: 2.39.2): Port Range Forwarding TCP 1433 and UDP 1434

Small Business Server 2003 Premium (Server Name: Server01)

Two network cards: Internet Ionnection and Local Area Network
Ran: Configure E-mail And Internet Connection Wizzard
Ran: Remote Access Wizzard (disables access to Windows Firewall)
Note: Remote workplace, Outlook Web Access, Sharepoint, etc, on ports 443,444, 3389, 4125 All work remotely - so Linksys router and RRAS port settings are working.

Routing And Remote Access(RRAS) >NAT/Basic Firewall > Internet Ionnection > Services And Ports

Added TCP Incoming Port 1433, Private Address 127.0.0.1, Outgoing Port 1433
Added UDP Incoming Port 1434, Private Address 127.0.0.1, Outgoing Port 1434

SQL Server 2005 Standard Edition version 9.0.3042 (installed on same machine, default instance ID MSSQLSERVER)

By default: TCP protocol is enabled and local remote connections are enabled on standard Edition. Also by default: MSSQLSERVER automatic/started/running and SQL Server Browser automatic/started/running

Ran: SQL Server 2005 Surface Area Configuration to confirm MSSQLSERVER instance settings are running.
Using: SQL Server Authentication: Login and Password
"sa" is a default account that works locally.


SQL Server Configuration Manager:

MSSQLSERVER protocols: Share Memory and TCP/IP enabled
TCP port 1433 by default (confirmed listening by ERRORLOG)


Microsoft SQL Server Management Studio

Database Engine lists SERVER01 (instead of SERVER01MSSQLSERVER - the default instance is not named explicitly)

Created database "Test" under SERVER01 > Databases.
Created table "tblCategories" in "Test" (included some fields and data)


Server-Side Successful?


netstat -ano | findstr 1433
TCP 0.0.0.0:1433 0.0.0.0:0 LISTENING 2004

Client-Side

Ping Successful

ping <xxx.xxx.xxx.xxx>
Telnet Successful (blank screen)

telnet <xxx.xxx.xxx.xxx> <port#>


TEST ASP.net Web Page Button Sub

I have this button on a page at Godaddy.com connecting to an instance of MS SQL provided by Godaddy and there is no problem connecting to that SQL Server.

Public Sub TestSQL_Click(Sender As Object, e As EventArgs)

Dim rdr As SqlDataReader = Nothing
Dim conn As SqlConnection = new SqlConnection("Data Source=tcp:xxx.xxx.xxx.xxx; Initial Catalog=Server01 blCategories; User ID=sa; Password=xxx")


conn.Open()

Dim cmd As SqlCommand = new SqlCommand("SELECT Category FROM tblCategories;", conn)
rdr = cmd.ExecuteReader()

rdr.Close()
conn.Close()
End Sub


ERROR:
The follworing error occurs or variations of it depending on different connection string configurations:

Occurs at: conn.Open()

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: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)


THOUGHTS

Possibly a bad connection string or Microsoft security issue.

I've attempted many other connection string formats such as:

Dim conn As SqlConnection = new SqlConnection("Data Source=xxx.xxx.xxx.xxx,1433;
Network Library=DBMSSOCN; Initial Catalog=Server01Test; User ID=sa; Password=xxx")


But I continue to receive connection failure messages (or invalid connection string errors for incorrectly formed connection strings).

I've tried disabling RRAS and Windows Firewall and the same errors resulted.

Any feedback would be appreciated.

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.

Jan 22, 2008

My site works fine in VWD2008 express, but I get this error when I try to use it on my live website.
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. 
According to this article: http://support.microsoft.com/kb/914277  I am supposed to:




1.
Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration.
Ok, there is no such program in this folder.  The only thing in there is "SQL Server Error and Usage Reporting"...
 The other thing I am greatly concerned with is this:  All is want is for my webpages to be able to access my database for user authentication.  I DO NOT want to grant the internet rights to remote connect to my database.
