This morning, one of my development machines died unexpectedly from a BSOD. I haven't been able to find any information from Google, so I'm posting my experience here for others to find.
The culprit seems to be ipnat.sys, which is interesting because even though I have a complex network setup, Windows doesn't handle the NATing. I'm running XP SP3 on this laptop, with ipnat.sys 5.1.2600.5512, modified Monday, April 14, 2008, 12:27:16 AM. The OCA failed because I had the minidump open in WinDbg at the time (oops).
Detailed network setup at the time of crash (10 adapters total):
- 1394 (FireWire) port - disabled
- Builtin wireless - disabled
- Dialup connection via physical modem - enabled but phone line not plugged in
- USB wireless - active, with Internet access
- NIC - active, local access only
- PCMCIA cell tower wireless ("dialup") - enabled but not inserted
- VMWare VMNet1 for virtual machines - enabled but not active (no virtual machines were running)
- VMWare VMNet8 for virtual machines - same
- VPN virtual adapter for OpenVPN connections - disabled; no longer used
- VPN virtual adapter #2 for OpenVPN - same
VMWare and OpenVPN both handle their own NAT, and adapter #4 is *not* shared over the network on #5, so I don't know why Windows was doing something with NAT.
Anyway, here's the WinDbg analysis:

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: 003a003e, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000001, value 0 = read operation, 1 = write operation
Arg4: ed878886, address which referenced memory
