Hi
I'm having the problems with my Windows 2000 web serwer (aspx platform).
Could You help me. Please.

The server sametimes work properly for 1 months, and sametime reboot 10 times in one week:-(

The Error code in the event log are:
ErrCode: 0x000000d1 (0x0000002c, 0x00000002, 0x00000000, 0xbea8121b). Microsoft Windows 2000 [v15.2195].
ErrCode: 0x0000001e (0xc0000005, 0x804d9e25, 0x00000000, 0x00000004). Microsoft Windows 2000 [v15.2195].

I have also Windbg Bugcheck Analysis (of the last memory.dmp file):

!analyze -v

BugCheck D1, {2c, 2, 0, bea8121b}

Probably caused by : TDI.SYS ( TDI!CTEpTimerHandler+b )

kd> !analyze -v;r;kv;lmtn;.logclose;q

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: 0000002c, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation
Arg4: bea8121b, address which referenced memory
