I suppose you have a counterfeit hardware for an original Ncomputing software built-in. The only solution to that is NOT TO UPDATE YOUR WINDOWS XP SERVICE PACK 2. Once you updated your Windows XP, your PC Station users cannot connect to your SERVER anymore.
If you have done the updates, just UNINSTALL the updates.
