[Condor-users] Windows executor nodes loose communication to Linux CM after its restart

[kschwarz@xxxxxxxxxxxxxx]

Hi all,

When I restart the Condor Central Manager
machine (linux), I loose communication to Windows executor nodes that are
in other subnet. Executor nodes on same subnet refresh their communication
to the CM.
Login in the executor machine and stopping/starting
condor service restores communication. This is not supposed to be the common
procedure.
No local firewall is enabled (Windows
Firewall is off and Firewall on CM machine is also off).
See MasterLog file attached. 

Is there any guideline to avoid loosing
the connection?

Thanks, Klaus
