I have this problem where my workstations can't boot to PXE. After aprox. 2 to 3 minutes they get an IP address from the DHCP server, but then give me:
ProxyDHCP service did not reply to request on port 4011. Here's the facts:

- Zen7 is installed on OES2 (SLES10-SP1) with no firewall running.
- DHCP and PDHCP are on different machines (DHCP is on windows) so no option 60 is set.
- Workstation and server are (for now) in the same VLAN.
- TFTP, PDHCP and Prebootpolicy services are running and are configured throught their conf files to the best of my knowledge.

I do remember that when I installed zenworks it encountered an non-fatal error on the PXE installation. It does seem to be running, though.

The questions are:
Is there a way to verify that the all services are OK?
Have I missed something?

All help appreciated. If anyone of you needs to look into config files I will be happy to post them here.
