Recently our server hangs after a few days of use, it becomes totally unresponsive. When you try to physically log into the console the login screen is missing, you only have a blue background and you can move the mouse cursor. The disk lights keep blinking so it appears it's still doing something except when you try to rdp or you have an existing session the desktop doesn't seem to respond to mouse interaction or keyboard input and also the taskbar is missing. We have monitored cpu, memory, network and disk usage using perfmon, everything seems normal as far as we can tell and nothing is logged in the event log when the server hangs. The only way to get the server running again is by hard resetting the server. I have found the following KB article:http://support.microsoft.com/kb/969289 Which seemed to fit the bill, except the hotfix that is available for download is a much older version than the one that's installed on the server, the last update on the mrxsmb.sys is dated april 2011. The server has win2k3 r2 standard x86 with latest service pack and patches, it has the following roles, DC, DNS, DHCP, WSUS, WDS, File & Print server. We thought defective hardware was the culprit but after swapping the hardware the problems reappeared. We've been struggling with this issue for awhile now, any help would be appreciated. On a side note we have considered the anti-virus software but the virus scanner isn't logging anything strange.
