Environment
Novell GroupWise 8
Situation
If the GroupWise Windows client is running on a VMware virtual
Machine, an 8503 error might be returned when trying to proxy
another user's mailbox or display a Multi-User calendar.
Resolution
To eliminate this problem, the VMware adapters will need to be
disabled on the workstation:
- Right-click My Network Places, then click Properties
- Right-click each adapter, then click Disable
