NT SBS server boot problem

[unit512]

We have WT Small Business Server 4.5 with SP6.

The c: drive is NTFS (SBS must be NTFS boot) with 2 gig. The d: drive is NTFS 10 gig.

The server is a Dell Poweredge 2300 with a raid array.

The system was working fine.

Now when I reboot I get:
"PAGE_FAULT_IN_NONPAGED_AREA
0x00000050 "

The system does a memory dump to memory.dmp and cycles for a reboot. I get the same error.

I CAN reboot into VGA mode, however. Everything seems to work.

I tried deleting and recreating the pagefile.sys file.

I tried restoring the files and registry from tape. Same problem.

Does anyone have any input?

thanks,
