Users see all printers in Citrix XP

We have a Win2000 network with Citrix XP farm. When a normal user logs into a citrix session they see “all” the printers on the network instead of just the printers they setup. We have looked at Citrix website and see others having problem but no solutions. We have the latest service packs on Win2000 and Citrix XP. We thought maybe the profile was messed up so we picked several users and deleted all the printers in a Citrix session. When they wait for a while all the printers reappear again. Weare at a loss. Any ideas?
