How Do I Modify my Connection String?

[cmcadmin]

I am getting this Error Message when I try to access my Forum:



Code:
---------------
Code is only visible to licensed users, and only when logged into the forums.
---------------



I posted the problem over on vB.com and I was directed to try posting over here.

My host is insisting that after a change they made to the server, that I need to modify my connection string with this:



Code:
---------------
Code is only visible to licensed users, and only when logged into the forums.

I have no idea where I need to make this change.

Help is Welcome...
