We are no longer experiencing a slow down or crash over time more what we would call a significant slow down for the amount of users vs hardware on the servers. DL380 G6, 36GB of Physical Ram (34 available to windows) Dual Intel Xeon 2.8, 16 Cores, x5560 Windows 2008 SP2 Problem We are seeing server instability around 50 users, 45 seems to be the limit. With servers of such huge specs does any list legend have any further ideas what we could be doing wrong? Any suggesitons would be very much appreciated!!!!! Thank s in advance for any assistance or even reading this Cheers James OTHER INFO Could it be BIOS settings?
