Have a Server 2005 network that we added two new computers to. The new computers are windows 7 and Primary is set up as a Raid1 with it's own network of server 2012. Computer2 was connected to Primary and a new reporting program functioned correctly. Once installed into the 2005 server, computer2 and another computer already in the network will not run the reporting system and return error 26.
I have already enabled sqlbrowser.exe, sqlserver.exe, and placed exceptions for ports 1433 and 1434 into both firewalls to ensure it isn't those issues.
Any other comments/tips that would clear this issue, besides it being a connection string in the program. The program was written solely for this Company and I am working with that code writer to see if any code issues.
