Hello everybody!

I need your help. I installed the SolidWorks Enterprise PDM 2012 on my network andiinstalei Server SQL Server 2008 R2 and the file server, database server and Web server!

Passwords that was put:

Login: sa

That was just for testing!

What happens to my machine that is in the same network when I try to add a server, itsays:

The user name or password entered is incorrect.

Why is this happening?

Can anyone help me?
