Vista - vpn and ndiswan

Hello all,

I suppose I should have seen this one coming. I installed a copy of Vista
Home Premium on Tuesday on a Gateway m285 laptop. For the most part, it works
just fine. However, I have a reoccurring problem when I try to connect to the
VPN at the University of Nevada, Reno.

I can establish a wireless connection and establish the VPN. Shortly
thereafter the computer crashes to a blue screen. The error message at the
top of the screen reads IRQL_NOT_LESS_THAN_OR_EQUAL_TO and at the bottom of
the screen there is an entry for NDISWAN followed by why I think are some
hexadecimal numbers.

I think I've resolved the problem by disabling the modem in the system
device manager. However, I'd like to have my computer up and running with all
the parts I paid for.

Does anyone have any suggestions?
