Hello I have a client who has recently been having some explorer windows hanging. I think I have it narrowed down to when there are over 15 people on the server and someone try's to print a larger file explorer and application become unresponsive for 15-45 seconds for almost all users. Spoolss.exe spikes up to maybe 50% for the time. This happens on either of the 2 servers in the environment. They are currently running Win2k sp4 , MPS XPE sp3. Hardware in HP server with Dual 3.6 and 4 Gigs of ram They have some of the Windows post sp4 patches installed. I am going to suggest they consider the upgrade to PS 4.0 or at least Sp4 for XPE and the few post SP hot fixes. Has anyone else seen a similar issue? Thank You Brian Rota,
