SYMPTOM

In User Manager, you receive the following error message:

The handle is invalid.

You are not able to perform simple administrative functions in User Manager at this point.

CAUSE

User Manager caches remote procedure call (RPC) handles on remote workstations. These handles are then used to do various operations on the remote machine. These handles are cached because of the relatively high cost of establishing an RPC session. Under some circumstances, these handles can become invalid. For example, if the domain controlling server goes down, cached RPC handles will no longer be valid.

RESOLUTION

To refresh RPC handles and restore any RPC sessions, do one of the following:

  • Change the focus to another domain by choosing Select Domain from the Computer menu. Then, change the focus back to the original domain.


-or-

  • Exit and restart User Manager.


-or-

  • Refresh connection information by pressing F5.
