DR Probs with actual nightly builds

[Komposer]

hi,

im using the actual nightly build for maya 2009/X64 - XP64.

since weeks, ive the prob, that when I use DR the slaves renders the first job perfect.
But at the end of renderjob they dont close DR session imidiately.
It needs 1 minute or more to be ready for next DR job.

the errMesage on the slaves is "currently busy with 0.0.0.0" !!
And, the slaves show the message, that they receive job from host 192.168.0.100!
But this host doesnt exist in my farm!
The master machine has .102 !!! and not 100..

btw, when I use RT and in the next moment DR, its the same prob...
waiting for closing session from host .100.

What can I do?
Any news on this prob?

thanks

sorry - I think I found the prob...

a few weeks before I made some tests with automatic IP adress!
and I had forgot this!
so my master host had the adress .100!!!!!

no I switched it back to .102 - manual IP and everything works perfect!!!!!

dont know, why the automatic IP made these probs - manual IP works!!

thanks gys
