You get an error in SQL Server 2005 like:

A connection was succesfully established with the server but then an error occurred during pre-login handshake(provider SSL ,error:0)………………

Most likely you cant connect to management studio. In this scenario sometimes you can make remote connections from another client. The easiest solution is to run “cliconfg.exe” network utility and remove the force encryption option and enabled protocols should contain both “TCP/IP” and “NAMED PIPES”.

Hope this helps.
