Hi, At the beginning of the year we upgraded to Windows 2008R2 X64 Datacentre for our terminal server. We have been having regular server crashes due to suspected printer driver issues. Our terminal server has been crashing 2 - 3 times a day. Two weeks ago I installed NOD32 4.2.35 on all of our servers. Our print server and terminal server have been crashing frequently. The terminal server is stable for 5 to 30 minutes only. I figured that the terminal server was terminally damaged from 3 months of crashing so I rebuilt it from scratch yesterday. All was good up until the point where I reinstalled Nod32 4.2.35, the terminal server started hanging at 100% CPU. I reverted to Nod32 4.0.474 and all was fine. I spoke to our NOD32 rep and he suggested 4.2.40, this also locks up our terminal server instantly. My really question is... Could our print driver issues be caused by NOD32 AMON scanning? Does anybody out there do anything special for printer drivers? Is anybody else having issued with Windows 2008R2X64 terminal services and NOD32?
