I have this old asp.net application that I've been using for years, for some reason after I press the login button I get this error:
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)
The funny thing is that the login routing ends well but this errors keeps appearing, so I made a new clean web project (vs 2010), get into the login screen, enter a fake user name and password, press login and it keeps loading for a minute apparently looking for some server, and after that I get the error.
If I look for the specific error in Google I get lots of forums on it, but they are for the real symptom when you're actually trying to connect somewhere, since I'm not doing and connection its really hard to find a solution
