@zaccx32 said in Pxe-Boot gets hung up on TFTP:
I did find a way to identify which machines are being affected by looking for extremely slow copy speeds when deploying files with PDQ. 4MB files will take over an hour to copy on machines that are being affected.
This here kind of tells me its network infrastructure. What I would do is look at the network switch port (hopefully you have a managed switch) and look at the port counters. See if you are having a lot of crc errors. Can you generalize and say all computers from area A have a problem but not from area B. If this is the case then the troubles may be on an uplink port between the area A switch and the next switch in line. Again the port counters might give you a clue to what is not right. IMO if you can duplicate the error with 2 different servers then its probably not the FOG server at fault.
I did notice something in your dhcp screen shot. Its not a problem with fog, but in your polycom scope, you should probably remove the undionly.kpxe boot file name. Its not relevant to a voip phone and may cause problems.
The other thing since your dhcp server supports profiles you might want to take a look at this wiki page to setup profiles for both bios and uefi booting: https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence#Using_Windows_Server_2012_.28R1_and_later.29_DHCP_Policy
