Netware 5.1 SP2a, BENW latest Version.

After 5 Weeks of no Problems, i get the following error.
My masterserver says "Failed to connect to the agent accelerator" to all
my 3 agents. But the agent accelerator startīs without errors and is still
running. Use agent accelerator over IP is enabled. No Problem with the name-resolution
(i found a hint in the knowledgebase).

Thanks a lot for good ideas ...
