Hello,
Did you also see error 53?:
Error 53 occurs when the client did get a DHCP address, but failed to get a response from a PXE server. A few things could cause this:
1) PXE server is on a different network segment from the PXE client and no DHCP Proxy or helper address is installed (on the router).
2) PXE Serer service has stopped (apperently not in your case).
3) Your PXE server and DHCP server are on the same server and your DHCP scope option does not include the option 60 that it needs for this configuration. Re-add option 60 to the scope with the value of "PXEClient". If option 60 is not available to add, re-install the PXE service by running PXE.EXE from the RDP CD.
4) No Boofiles were created during setup. Open BootDisk creator and check that you have atleast 2 bootfiles (a managed and an Initial). In 1.4 they are called defpxemg and defpxenc, respectively. In 1.3, the images were created, but did not appear in boot disk creator. Re-create them to be sure.
Cheers,
Westlander
