I am on ZCM 10.1.3 with single server implementation (regular DHCP service is not on the same ZCM server).

I don't use PXE boot everyday. However, many times when I tried to do PXE boot to access the ZENWork Imaging menu, I have to restart the Proxy DHCP service on the ZCM server. Otherwise, it will not be able to contact the Imaging server.

As soon as I restart the Proxy DHCP service and then do PXE boot, I can connect and reimage the device.

Any suggestion for troubleshooting if I get the same issue?

Thanks in advance.
