We are rolling out Windows XP with Zen 6.5. Most users have Zen Mngt
Agent installed, but some have the Agent that came with Zen
6.5 install. We also have not applied any patches to the Zen 6.5 server
yet (we are very busy with XP rollout).

Periodically we will get the following error when attempting to Remote
Control a workstation:

1489: The workstation is not imported into the tree. The directory mode
of authentication is unavailable.

Searched - found no TIDs that help me. Any ideas?
