I had the following problems with the unattended XP with SP2 CD.

1) Cannot run WMIC on the command prompt. It always show:

Please wait while WMIC compiles updated MOF files.

Parsing Mof File: C:\WINDOWS\system32\wbem\Cli.mof(Phase Error - 3)

Compiler returned error 0x80070005

2) System Information (msinfo32.exe) has this error:

Can't Collect Information

Cannot access the Windows Management Instrumentation software. Windows Management files may be moved or missing.

3) On Dell machine, the processor information is missing, only the total memory is shown. As such the OMCI software that come with Dell do not work!!

I don't have such issue on XP with SP1 unattended CD.

Has anyone faced this problem before?

Maybe you should make ISO again or you should make the unattended XP CD again..

because I have not faced these problems.
