I'm running VS 2015 and SQL Server 2008 R2 on a remote server.
When I try to connect to my database via SSMS, everything is fine. When I try to connect via Visual Studio Server Explorer, it also works fine, but when I do it through C# SqlClient, it times-out.
I'm always using integrated security.
Everything is running fine on my colleagues computer.
What can cause that? How can I debug it?
Error message :
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. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=1879; handshake=1
Simply deleted thee solution and re imported it from our version control and it worked (rebooting wasn't enough)
