On the 1.4 files - I had that problem once, but can't remember how I solved it :whathuh:
I know this may sound redundant, but just re-check ALL IP's, I know you more than likely did this loads of time already, but just to make sure. Also make sure the Server name is entered in all the right places and is Case specific. Server is different to server I think.
I'll give it some more thought and see if I can remember anything else.
As for 1.9, Once I was told about RegServer thing, and the 2 login gates I was fine. So I don't know how to help on that I'm afraid.
