[vetter <vetter@xxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

we have a problem in the negotiator. For some reason it can not 
communicate with the scheduler on the clients. 

negotiator.log:

There is no firewall running.

The last change was, that i moved the NIS server from another machine to 
the central manager. 

Any hints?
