OK, I posted a very similar error about 10 months ago for this server. I updated the Dell Poweredge 700 Windows 2003 32-bit Std with the latest drivers at that time and ran a memory check overnight.
This morning I got the system error category 102 event ID 1003:
Error code 0000000a, parameter1 00000044, parameter2 d000001b, parameter3 00000001, parameter4 8083d05e.
Looking at Minidumps, it looks like it is occurring every 2 months or so. Mini100211-01.dmp
