hi,

we are getting frequent dump error in my Windows 2000 server with SP4 which leads to unexpected shutdown.

For this I tried to analyse with memory dump with windebugger and i got the below output for analyze -v

Please guide me what makes my system frequent reboot

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
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 kernel debugger is available get stack backtrace.
Arguments:
Arg1: 4c494600, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation
Arg4: f643c932, address which referenced memory
