DUMP DATA on WS2K3 servers w/Citrix

Having a heck of a time with several servers getting BSOD's during the nights and early mornings. It seems that they're all fine while under load, and this only happens during off-peak hours. It appears to be some sort of driver issue, but I can't make heads or tails of this, and have the data dump in hopes that someone will be able to help. Note: These Windows 2003 boxes have NO service pack applied.

Thanks!

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: ffffffff, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation
Arg4: 804faeb5, address which referenced memory
