I am using windows 2003 professional operating system. I deployed my asp.net web application on it. It generated an error. I provided you a snapshot of it.
===============
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. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: 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. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Source Error:
public virtual businesslogic.tlinksme.ShoppingCartClass.Cart SCart {
get {
return ((businesslogic.tlinksme.ShoppingCartClass.Cart)(this.GetPropertyValue(&quot;SCart&quot;)));
}
set {
===============
Actually, I am using Custom Profile for shopping cart as Binary.
I did not get where is the error. I googled many web sites, but I did not get the exact answer.
For your information, my SQL server 2005 has been configured correctly. SQL server 2005 names instance is running, and a web browser is also running. I have enabled TCP/IP as well as enabled remote connection.
One surprising thing is that when I deployed another server like XP, it is working well. No error at all, but when I deploy on windows 2003, an error is generated for network interface.
I need your help.
Bye.
Thank you. </description> <content:encoded><![CDATA[<p>Hi.</p><p>I am using windows 2003 professional operating system. I deployed my asp.net web application on it. It generated an error. I provided you a snapshot of it.<br

I deployed my asp.net application in one server and my application database is on some other server.
When I try to connect to the sql server datbase from my application then i got following Error Message.
&#8220;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. (provider: SQL Network Interfaces, error: 26 &#8211; Error Locating Server/Instance Specified)&#8221;
I googled on this Error.I checked the Configurations on sql server like
sql browser is running. allowing remote connections go checked and tcp/ip enabled.All Configurations are correct.
Still i got the same problem.
Please Some one Help to solve my problem. </description> <content:encoded><![CDATA[<p>Hi,</p><p>I deployed my asp.net application in one server and my application database is on some other server.</p><p>When I try to connect to the sql server datbase from my application then i got following Error Message.</p><p>&ldquo;A network-related or instance-specific error occurred while establishing a connection to SQL Server.

isPermaLink="false">http://helpdeskgeek.com/?p=4759#comment-30602</guid> <description>I have a windows service written in c# that tries to connect to a remote SQL Server 2005 via ISA Proxy Server. The server on which windows service runs has ISA Proxy Client installed. The required firewall settings allow connection to the SQL Server on port 1433. We have tried creating a DSN and also tried using &quot;telnet  1433&quot; commands to verify connectivity. The network guys tell us that the application should be completely proxy server agnostic and that is what it is. However, they are telling that when the application tries to connect to the SQL Server, it is directly trying to go via the ISA Proxy Server rather than via the ISA Proxy Server Client (which encapsulate the network packets before forwarding to the ISA Proxy Server) which results in exactly the same error.
The windows service also consumes some WCF webservice services and normal SOAP web services within the domain.
The peculiar thing is that I created another light weight windows service which does just what the regular windows service does in terms of SQL connection and that seems to work without any issues. Both windows services run on the same server with the same credentials. </description> <content:encoded><![CDATA[<p>I have a windows service written in c# that tries to connect to a remote SQL Server 2005 via ISA Proxy Server.
