Hi
Thank for both the replies, I tried both things and neither worked.
However, the issue has been resolved. We have something called 'Discover' a piece if software installed via SOLUS 3 which was not installed on any of the clients. Once this was installed it all started working!!! - Perhaps this is something very trivial that should have been done - SIMS technical people actually installed SIMS on our servers, so I had no clue. It was just a guess that worked.
I have had atleast SIMS tech support log into our servers several times, they never checked if Discover was insatlled on the clients.
Thanks again for the prompt replies.
