Dear all
1 Physical host: W2k12R2, 1 Hyper-V virtual switch.
1 Hyper-V VM with W2k12R2 DC with DNS, DHCP, WDS.
1 Empty Hyper-V VM Generation 2 UEFI booting from network.
Problem: Error "PXE-E16: No offer received" on the empty Hyper-V VM when trying to Uefi boot from WDS in AD integrated mode.
I verified that it works when WDS is set-up to standalone mode. See also: https://social.technet.microsoft.com/Forums/windowsserver/en-US/ceca6149-bedd-4860-8a7f-a1c83bf99aa4/wds-efi-bios-wont-pxe-boot-into-efi-mode
PS: Switch to standalone mode: On the WDS server: wdsutil /verbose /uninitialize-server /server:<servername>; wdsutil /verbose /progress /initialize-server /server:<servername> /reminst:C:\RmInst
Cause (found by Netmon IP traffic monitoring):
The Client asks for the TFTP Server on UDP port 4011.
The TFTP Server takes more than 8 seconds to reply on port 4011.
This seems to be due to NbtNs (Netbios name search) broadcast queries searching for 1C Domain Controllers.
Solution: ???????
Any help is much appreciated.
