Dear friends, good morning!
We use a Windows Server 2008 R2 with Microsoft Fofront Threat Management Gateway (TMG) to concentrate some branch offices VPNs.
Today this server stopped working and rebooted.
I analyzed the MEMORY.DMP file and I noticed that it was caused by RASPPTP.SYS file while it was trying to release some memory buffer.
I'm pasting the MEMORY.DMP file content below.
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: 0000000000000024, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000001, value 0 = read operation, 1 = write operation
Arg4: fffff880035ce05f, address which referenced memory
