NEW PXE / WDS Issue on Primary Site Server after Recovery


New Member
Hi all!

We changed our Site Server from Server 2012R2 to Server 2022 by using sccm recovery. This process was successful, exept our pxe isn't workling properly.

Our clients are visible in SMSPXE.log and WDS Event Logs, but after Msg Type: 5=Ask and successfuly transfered bootmgfw.efi they are sending a new Msg Type: 3=Request and loop this until Timeout and Error 0x102. I checked our internal firewall more than twice an can see that traffic is passed and done (wdsmgfw.efi is successfully transfered).

I've been investigating the issue for 3 days now and I'm starting to not know what to do next. Maybe someone here is having a good idea for me...
