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: 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.

Hi Roy, Only running rdp sessions are accessible, the server won't respond to any new requests, like rdp or smb, when we do a nslookup we receive a message that the host is not available on the network. We don't have any scheduled tasks running, because the server hangs and seems to be doing something it doesn't crash with a bsod and so we don't have a memory dump unfortunately. Because it's a production server we can't eliminate roles, we are however thinking about placing the shares on a different server, that's basically all we can move at the moment.

have you tried to rdp into the server when it fails? is there a scheduled task that coincides with the "hang"? do you have a memory dump you can post here and get one of the Microsoft weenies to review? have you tried eliminating roles one at a time to isolate a possible problem?

Hi Ben, If you could it'll be very much appreciated. By the way I looked up the support site of the server and unfortunately we're already running the latest videocard driver.

Hi Arthur, We already have the latest firmware and drivers installed including the latest windows updates. By the way, the problem we're having is on a Windows 2003 R2 Standard server and not windows xp. The server only hangs when in use, like three or four business days, in the weekend the server runs fine, the only thing running then are the backups. We ran a hardware check using HP SmartStart and everything came out fine, no problems with disks or storage controller, which was also a suspect.

I think I'm going to create a support ticket, last friday the server had a system hang so we rebooted, 45 minutes later it had another hang. We're now moving some of the shares to another server so people can at least go on with their business untill we find out what's causing the system hangs.
