System is Zen 6.5 SP1

When trying to remote control XP workstations that are registered in the
tree, I get the following errors depending on workstation:

- RCCONSOLE MFC error
- error 1489
- The workstation is not imported into the tree
- The directory mode of authentication is unavailable

I've tried both Zenbrowser.exe and remote control from within C1.

This is not good. Any ideas?
