I think Windows 2000 and XP can run the Condor jobs even though the user 
is logged in. I haven't tested it with NT. I had Condor using the 
machines when the user is logged in. My main problem is if the user is 
logged in and he is using the main GUI which shares many DLL with the 
worker executables then I get 128 error. It took me a while to finally 
track that is the case since it is too random to know why this machine 
which run the job fine a couple of hours ago was now having error 128. 
May be you could check your nodes to see if the problem happens when 
there is a DLL your works executables share with the excitable running 
at that time.

That is exactly what is bothering me and the bad thing about it the 
randomness of it. It will be nice if there was a way to know if there 
was a user logged into the machine. Even though, it reduces the number 
of nodes that I have for computation, the resubmitting works since the 
user wouldn't even know that this happened, as far as he is considered 
the job is completed. That is one the good thing I like about Condor.

I think there is a solution for that,  I have seen an option to 
configure the negotiator not to send the job back immediately to the 
same node after a failure but I couldn't remember which option it is. 
May be Condors will enlighten us on this.
