I've been trying to setup WDS on Server2012R2 and am having trouble with the PXE boot response from the server. My infrastructure is as follows - WDS on Server2012R2 is a virtual domain integrated server with no other roles or jobs, DHCP server on another server, we have vlan environment with HP2920 switches in a stack handling layer 2 networking, several different models of HP laptops (which I'm trying to setup for imaging on this new WDS server). When I PXE boot the laptops I get the PXE-E53: No Boot filename received. The WDS server debug logs show the MAC of the laptop communicating with the server but recurring Event ID 32769 information events showing the following - [WDSServer/WDSPXE/WDSDCPXE] Client ignored - Seconds Since Boot=8, Response Delay=15. The WDS Verbose event ID 24581 shows the following - [WDSServer/WDSPXE][WDSDCPXE] Reply Sent - Request:0.0.0.0:68 Dst:255.255.255.255:68 Len:280.
It seems like the server and the clients are not establishing communication. Based on WDS documentation I have not configured DHCP scope options (66 & 67) although I have tried that previously to try to manually connect PXE boot clients and this has failed as well. Any ideas?
