I have been successfully using PXE Imaging on NBO servers for a few years
now, but based on ZEN 401, since upgrading our backend to ZEN701 I am
having trouble load DTS.NLM on the NBO.

PDHCP OK
TFTP OK
DTS AUTO FAIL
PMAP OK

We also load IMGSERV this is also AUTO FAIL but this could be because
DTS.NLM has failed.

Any ideas
