I have Visual Studio C# application that for years has worked fine. Recently it stopped working and what I found out was that they had replaced servers. The new server has been assigned the same IP address as the old server. The error message leads me to believe that my application is trying to connect to the server via named pipes. We do not use named pipes it should be using TCP/IP. Unfortunately there is an application on the server that uses named pipes. I have an ini file that is read containing the connection string. Is there a way in the connect string to specify to use TCP/IP? I specify the IP address in my connect string and the old server has been taken off line.
