Laptop bluescreens when not in docking station

I've got an IBM Thinkpad T43 laptop running Windows XP that works just fine when it is in the docking station on the corporate network. But when removed & booted up, it bluescreens with a "IRQL not less or equal" message in NDIS.SYS. This just started happening - it was working fine before. No new driver or windows updates were applied.

Help!
Thanks.

I ran SIGVERIF and it reported some unsigned drivers - but only one was modified recently. A net adapter for VirtualBox that was installed back in June. Gonna try removing that and see if it behaves.

Any other ideas?

I didn't screw with my default NIC adapter yet. But after removing the net adapter for VirtualBox, I was able to reboot 2x without the docking station and it worked fine. The real test will be tonight from home, when trying to connect to my WAP at boot up.

Hi -
THANK YOU. I do hope the 15 minutes BSOD-free uptime has greatly increased by now.
