Over the past few weeks I have started to have issues with servers hanging at logon and users freezing up while working in PS4. When the server is restarted the problem goes away. When I try to logon to the affected server the logon screen will hang at "Mapping Client Drives", or "Restoring Network Connections". Nothing obvious appears in the event viewer (some crashed applications but I think this occurs after the problem starts). So on a hunch I tried to stop the print spooler service. The Citrix Print Manager Service can't be stopped and errors "The Citrix Print Manager Service service could not be stopped" and "System Error 1051 has occurred". The service then shows "stopping" in the MMC but never seems to stop. The most recent printer installed was the HP LJ 4250dtn which is on the HP compatibility guide for Citrix and I confirmed the version is correct according to the HP guide. My current environment is PS4 Advanced on Windows 2003 with SP1. PS4 hotlist fix is, PSE400R02W2K3001, PSE400R02W2K3002, PSE400R02W2K3004, PSE400R02W2K3006, PSE400R02W2K3010, PSE400R02W2K3018, PSE400R02W2K3027, PSE400W2K3R02.0.1. I'd appreciate any suggestion on how to pin down the cause of this intermittent hanging. The hanging seems to occur on any of the servers in the farm (3 in the farm) and is happening almost once per day on one of the servers. Until recently the farm had been very stable and no major changes have been made. Does the "Citrix Print Manager Service" failing to stop conclusively indicate this is a printer related issue or is this just a symptom of the problem? Any suggestions would be most welcome.
