DRIVER_IRQL_NOT_LESS_OR_EQUAL crash after SP3

[David Ellis]

Since installing Service Pack 3 to Windows 2000, I get frequent
bluescreen stops:

STOP: 0x000000D1
DRIVER_IRQL_NOT_LESS_OR_EQUAL
wanarp.sys

Sometimes the system reboots by itself, and sometimes it hangs on the
bluescreen and has to be powered off and on.

This never happened before installing SP3, and installing SP4 has not
helped. I have also installed a fresh TCP stack, every critical patch
on Windows Update, and all drivers that might be even remotely
relevant. No relief.

It was suggested that these errors might be caused by faulty RAM, so
I installed and ran RAM-scanning software, but there appear to be no
memory problems.

The currently installed copy of the wanarp.sys driver is version
5.0.2195.6601. Would it be helpful to go back to the version that
existed before SP3 (5.0.2195.4874)? Or would that destabilize the
system even further?

My sysadmin says my only choices are to live with the crashes or wipe
the entire disk and reinstall the operating system, applications and
user data. Any better ideas?

Hi David,

I have seen this specific stop error in the past, with these parameters
when some specific software is installed on a machine. I have seen this
when a Cisco VPN client is installed on the machine. If this is installed
you can try uninstalling or disabling this. In some cases it has required
removing the Filter Driver from the registry.

Otherwise you could try debugging the dump file that is created and trying
to determine the root cause of the dump. You can get the debugging tools
here:

Please be aware that setting up the debugger and learning how to debug is a
bit of an art form. Setting the debugger up can be fairly difficult if you
are not familiar with the tool.

Thanks,
