I was recieveing a connection error on several of my modules. This is the reply I posted in another forum, when I found out what the solution was.Leupold thank you for pointing me in the right direction. I was using a straight text editor, and didnt notice that the legacy section for MSSQL 2005 was commented out! Therefore even when I replaced the string, it didnt take affect.
I checked the update version of the 4.5 Install and release.config comes with this section commented out Those of us with Server 2000/2005 need to make sure we move the close to the comment section.
