I'm trying to capture a drive image of a windows xp pro machine. I've gone through the steps and resealed the machine.

When i try and network boot the PXE instantly gives the message "PXE-MOF" and ends.

I have managed to get network boot to work on this machine whenever XP is not resealed.

I have tried Multiple times to get PXE to work after resealing windows, but with no luck. As soon as i unseal it, PXE works every time.

I know PXE is supposed to work independent of what's on the hard drive. Is there any way that resealing windows could cause PXE to stop working.

PXE should work even if you unplug the hard drive. I have no idea what's going on here. – Shinrai Nov 12 '12 at 18:02
I know that was what i thought too. I thought it might be a DHCP issue, PXE seems not to get that far – zeocrash Nov 13 '12 at 8:57
What exactly do you mean by "resealed"? – Ramhound Nov 13 '12 at 11:39

also what's the negative vote for, this is a perfectly legitimate question. – zeocrash Nov 13 '12 at 11:52

this is very easy to trace with Wireshark follow the DHCP transaction, you have to see the client gets an IP and 2 parameters:

  1. TFTP server IP
  2. Name of the boot file (NBP).

sure it is a problem involving those DHCP parameters not provided correctly

The PXE doesn't seem to get as far as looking for a DHCP server, it exits before that. – zeocrash Nov 13 '12 at 11:54
the first thing a healthy PXE booting station does is performing a DHCP request... – Pat Nov 13 '12 at 12:29
