pxe-e55 proxydhcp service did not reply to request on port 4011

[TConn]

I am having problems with this error. pxe-e55 proxydhcp service did not reply to request on port 4011. 

This is Deployment Server 6.9 SP5 running on Windows 2008.  The DHCP server gives me an IP.

When running Deployment Server 6.9 SP2 on Windows 2003, the same Blade and  IP, I had no problems.

It was not upgraded, it was a clean install

I have done the following.

1- Added port 4011 and 402 to the Windows 2008 Firewall - rebooted server

2- Disabled the Firewall - rebooted server

3- Checked the PXE.ini to make sure it was correct

4- Checked the PXE Configuration and all is good

Any help would be appreciated.

Cheers,

Terry
