Re: [HTCondor-users] maximum of 9 dynamically allocated slots on Windows?

[Peter deVoil <peter.devoil@xxxxxxxxx>]

Folks,

Just so you know, we have a few windows 7 (enterprise sp1/x64) boxes
running 8.0.6 that have made 12 slots fine

Though a windows server 2003 sp2 domain controller refused to create
condor users at all. No big loss.
