Re: [Condor-users] not seeing Windows 7 CPUs

As mentioned in a previous post, I have a similar problem, perhaps with different symptoms?  I haven't been able to reproduce Brad's observations.  I would like to preface my question with the fact that I have a number of windows 7 machines and half of them work without any problems.  The other half have always had intermittent functionality, but now seem to be "broken" altogether.  Condor is running, but no slots show up in "condor_status".  If I try a "condor_status -direct bad.hostname" I get an error indicating no startd was found.  Now, if I log onto "bad.hostname", and do the same command as above "condor_status -direct bad.hostname", I can see all of the slots for this machine and their status.  So, some how, startd is running, but the condor host doesn't know it.  I can ping the condor host from "bad.hostname", and the reverse ping works as well, so the machines see eachother.  I don't see anything abnormal in any of "bad.hostnames" logs, and I cannot find the ip address for "bad.hostname" in any of the condor host logs.  What's truly troubling, is that the condor, network, AV/Firewall, and OS settings are nominally identical between "good.hostname" and "bad.hostname".  I'm not really sure what else I can troubleshoot here.  Any ideas?

Restarting the service fixed the problem of the Windows 7 computer's CPUs not being recognized or used, ONCE. The CPUs appeared after following your procedure, but after seeing the CPUs listed and attempting to use them, I then restarted the master and repeated the stop and restart process and haven't been able to repeat the first
(partial) success.

However, the attempt to use the Win7 CPUs while they were recognized in the pool was not successful. While I saw the execute directories being generated and removed as the jobs were submitted to and supposedly run on the computer, the results files were not sent back to the master and my monitoring program waited "forever" for them to complete, but the directories were long since removed from the execute directory.
