We upgraded all of our Server 2008 R2 servers with WDS to new OS 2012 R2 with WDS. After upgrade WDS no longer works, all computers will not get an IP address from DHCP after server was upgraded. We are not using DHCP Options since at this time we have added IPHelper address on each VLan The only change that has been done was a upgrade from 2008 R2 to 2012 R2
Any help would be greatly appreciated
