Hey, thanks all.
I actually found out how to do it. What I needed to do is the remotely install the same hot fix 5005 on the server, which does the trick for both ArchiCAD and BIM server programs.
Works like a dream now.
Thanks again.
Like with everything, it's the learning that takes up all the time. Once you get it, it is easy and fast.
Cheers.
