Problem With Remote SQL Access
Jan 8, 2007
I installed sql 2005 (server) in two Win-Xp machines and tried to access each other, it was working fine, after that I tried to mirror the data base (I already installed SP2 in both machine) then I am getting an error saying,
"A connection was successfully established with the server, but then an error occured during the preloging handshake.(provider SSL,error:0 - The certificate chain was issued by an authority that is not trusted.)(microsoft SQl Server)"
After that I could not connect the the sql remot. If any body knows the slution pls reply me.
Thanks

- When I disable "allow remote connections to this server" from server properties>connection page, I can still remotely connect to the server from SSMS...so what is the impact of enable/disabling it?
- what is the impact of changing the remote query timeout (on the same page) from default value?

Hi
I have a web application and SQL database on separate SQL 2000 server. I have no admin rights to these servers.The ISP gave me a VPN connection and password to manager my database.If i run the application from my home computer WITH the VPN connected the application works fine.However if i disconnect the VPN or try to run the application from the remote server i get this error:SQL Server does not exist or access deniedI have researched this problem extensively and CANNOT find a solution. The application and SQL 2000 database server are on different computers. The SQL user id and password are different from the VPN connection's.My web config looks like this:<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="mappedname" value="username"/>
<add key="mappedkey" value="password"/>
</appSettings>
<system.web>
<globalization fileEncoding="utf-8" requestEncoding="utf-8" responseEncoding="utf-8" />
</system.web>
</configuration>
And the application connection string is as follows:Dim usersql As String = System.Configuration.ConfigurationSettings.AppSettings("mappedname")
Dim passsql As String = System.Configuration.ConfigurationSettings.AppSettings("mappedkey")
connectionString = "data source=xxx.xxx.xxx.xxx;initial catalog=databasename;"
connectionString &= ";user id=" & usersql
connectionString &= ";password=" & passsql
I am obviously missing something. Not sure what or how to pass the permissions on properly.Can some kind soul please help me with this problemThank YouJeff

Hi all,
I encounter a problem of unable to access Remote Server after i placed my web application into the web server.
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 connection could be made because the target machine actively refused it.)
So I googled and tried lot of different ways of connecting.By piped name, IP, trying instance which that server don't even have one :X.I also tried typing in cmd > telnet localhost 1433It appeared that the telnet fail, i tried it on other machine, it works. So is it cause by denied of access through that port?I checked at the sql client network, it show 1433, i check the server too, it show 1433.I also checked if there's any firewall, it appear there is no firewall at all.The sql server i trying to connect is SQL 2000, it run by Windows Server 2003
Any advise or more information you needed to help me solve this problem?Thanks

I'm using SQL Server to store session state. The Sql Server is on the local network but not on the web server. I use impersonation and use account credentials for the ASPNET worker process:
<identity impersonate="true" userName="domainuser" password="pass"/>
I'm able to access all resources and execute all pages without any problem.
When an object is added to session state I recieve the following error:
"Cannot open database requested in login 'ASPState'. Login fails. Login failed for user 'domainusername. "
Here is my web.config entry for using sql server (with modified connection string of course):
<sessionState mode="SQLServer" cookieless="false" timeout="30" stateConnectionString="Data Source=xxx.xxx.x.xx,1433;Network Library=DBMSSOCN;Initial Catalog=ASPState;Integrated Security=SSPI" />
I've checked and given the user i'm impersonating the ability to do everything. I've granted access on all necessary files, added them to the DB and made the user a db_owner of the ASPState table. I can log in to a machine as the user, then access sql server using the windows authentication. I granted 'act as part of the operating system', 'access this computer from a network', 'log on as a service', 'log on as a batch job' on both the remote computer hosting sql server and the web server.
The strange thing is i installed the asp session state tables on my development machine, using the same configuration file to run everything, and was able to add an object to session state without any problem. But when i specify the remote server, i'm denied.
Anybody have an idea?

Here is the connection string i used:
"Data Source=<IP>,1433;Network Library=DBMSSOCN;Initial Catalog=<dbname>;User ID=sa;Password=<pwd>;"
i use that to connect to the remote SQL server, which has status of port 1433 at "Stealth"... do i need to open the port complete, if yes how i do that ?
does the SQL Server must use SQL authentication ?
Your help is greatly appreciated.

Hi,
I have an MS SQL Server 2000 database running on a local area network. The database contains product info that I would like to use to populate a web catelog being hosted off site.
Can someone point me in the right direct regarding common practices for using this product database, which is updated on a regular basis, to update my Web catelog?
I was thinking periodically the Web server could remotely query my product database for new entries (this does not need to be real time).
What do you think...

My ISP provide MS SQL Server. I can create my database name, dbusername and dbpassword through control panel and then I can access the database in ASP using this connection string "Provider=SQLOLEDB;UID=dbusername; PWD=dbpasword".
Before, I could also use my enterprise manager to create a new sql server registration using my web url, dbusername and dbpassword. But now it seems that my ISP blocks the port or something and ask me do everything through the control panel.
Does anyone have some idea to connect to a remote server thorough enterprise manager based on the infromation I have?
It would be very helpful for your opinion!

I am having issues with MSAccess and MS SQL for a new client. It worked in the past, but I cannot talk to the old computer guy?!# Here's the scoop. It uses an Access front end and ODBC to conect to the MS SQL 7.0 server. In the office they use a system DSN named DATA to connect using NT authentication. I've got the firewall configured for the two employees static ip addresses to goto the MS SQL server. On the remote machines, I have added a system DNS named DATA as well that uses MS SQL authentication. I setup the remote user accounts on the MS SQL server. Now heres the problem. I can test the ODBC from the remote omputer and it works.At first I could not get into teh database at all. I went in and updated the Access file connection strings to include a username and password. Now I can get into the Access front end and access the main page. (IT has a couple of buttons - Shpping, Inventory, Management, etc.) I can even click on these buttons and pull up the next page. (For example I can click on the management button and pull up a list of new buttons- one of which is Auto Exec Bob) NOw when I click autoexec bob or any of the others it takes a while and then give me an error. (SQLState 28000 MS SQL error: 18452 Login failed for user null. Reason: Not associated with a trusted SQL Server Connection.) If I click ok then I have a box that lets me uncheck the use trusted connection and sign in using my remote username and pass that I setup. Eventually I can access everything - one step at a time.Each time it tries to connect to the database it takes about thirty seconds to time out, then gives me this error message and I can log on again. Any help to sort this out would be greatly appreciated. Thanks in advance.

Version SQL 2012.
Exec sp_configure remote access running values is "1" by default. If set the value "0", what will be impact on both server and client side?
1. Client side: remote access option value is "1", it mean to allows executing stored procedure in remote client side by using SSMS. server itself does working all SP which was passed by through application(remote application server even SQL port enabled between application DB and App servers).
Impact: value is "0" developer does not able execute SP their Client SSMS side after connecting established in DB server.
2. Server side
Impact: Does it working Linked server if value is "0?

Hi,
I use a VS2005 application with a sql database. All is working well over a local network but I now want remote access to the system via the internet.
Is this possible? I have a fixed IP address & am wondering if I can just use the ip address as part of the connection string? (And if so - how!)

the error comes:
"An error has occurred while establishing a connection

(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.)"
AFTER IT WHEN I TRY TO ACCESS NETWORK FROM ANY MACHINE,
IT FAILS TO ACCESS WITH FOLLOWING MESSAGE:

I'm writing a piece of software that is designed to access data from SQL server. The office's server has SQL server version 7 installed. The software works perfectly when running on a computer on the network in the office. I however am trying to work out how to use use the software from my home computer and connect to the SQL server database remotely. I've never done this before and I'm finding it hard to find the right information.
Firstly, is it easy to do this? What do I need to do with the server in the office to allow this to work? Do I need any extra hardware/software? How will my software connect to SQL server? Is it as simple as changing the connection string to something like the server's ip address and sql server name?
I'm writing the software in Visual Studio 2005 professional and programming in VB.
Many thanks.

Hi,
I have written a VB program using an SQLExpress database on my machine, and I want other users to remotely access it. From what I have read, all I have to do for the Client machines is load on SQL Native Client and install the EXE. I have also enabled TCI/IP etc and setup the exceptions on my firewall. My connectionstring is
"Provider=SQLNCLI.1;Integrated Security=SSPI;Persist Security Info=False;Database=<mydata>;Data Source=<machinename>sqlexpress"
When I run the EXE on the client machine, I get the following error...
Cannot open database <mydata> requested by the login. The login failed.
I am totally new to SQL and would appreciate any help in getting this setup. Do I need to put my login details into the connection string so other PCs can log into my database..?
ACCESS was never this hard to deploy, but I really want to learn SQL.
Thanks in advance

I'm creating an app that will connect to a central sql server 2005 (hosted on a Win2003 server with Windows Firewall on). I added sqlservr.exe and sqlbrowser.exe to the firewall exceptions to allow for remote connections. Now, an admin I know is telling me that this is not secure and we must configure those 2 exe's to only be accessed by certain IP addresses. I want to make sure the database is very secure, but this sounds like overkill. ??
Questions:
Is this necessary (to limit access to these 2 exe's to certain IP addresses)?
How would I be able to distribute my application to different users if this is so?
How can I make sure that the SQL Server won't get "attacked" or "hacked"?

I have my normal SQL 2005 database....and another database (on the same machine) that is the default aspnet database. I use that for authentication of course. Everything is working well except now I need to (for a SP I'm creating) access the UserID field in the Users table (without the customer logged in). I know this isn't the best way to do it but....Can someone tell me how to programatically (from an existing SP) access the aspnet database? So I can just check something against the UserID (providerkey) I already have? The customer isn't logged in at this point. I have their UserID from somewhere else. Here is what I am trying to use now. IT Works in Query Manager but throws an error (...in this security context) when I run it in ASP.NET...SELECT @UserName=(select UserName from [aspnetdb].dbo.aspnet_Users where UserID=@UserID) Thanks.
