PXE-E55: ProxyDHCP service did not reply to request on port 4011

The error message can differ a bit as it is network card controlled. Unfortunately there is no single fix for this issue. There are a lot of causes for this issue. I will list solutions down here as I run into them.

Solution 1:

All approved and rejected devices are added to a database. If a device is rejected WDS will not respond to requests coming from this device. The best way to solve this is to clear the rejected and/or approved devices database. To do this log on to your WDS server and run the following command:

Wdsutil.exe /delete-autoadddevices /devicetype:rejecteddevices

Wdsutil.exe /delete-autoadddevices /devicetype:approveddevices
