Hi my problem is STOP 0x100000d0 have 10WS all the same HW except CPU, this crash happen often, but probably only on this one WS, i add file with memory dump, screen shot of event viewer and details about STOP error. BIOS and drivers are up to date, but Updates from Microsoft are switched off, SP2 with some minor updates are there. i haw tried over google find solution but this error is nowhere to find... the dump file can send to email, or let me know where to upload.
