    WDS PXE issue: PXE-E16: No offer received

    Issue Description:

    The problem server installed the follwing roles:

    • WDS
    • DHCP
    • WSUS
    • RRAS (Route and Remote Access Service)

    The WDS service is configured with Active Directory integrated, everything seems configed correctly. But a Hyper-V Gen2 VM client is not possible to boot with PXE. Message is "DHCP failed".

    If you redirect the vNIC and connect to the WDS server with a physical machine, you get a message “PXE-E16: No offer received“.

    Trouble shooting

    My steps to trouble shooting:

    1. I deploy a new WDS server with only DHCP and WDS service. This WDS service works fine.
    2. I capture the packages with WireShark for both WDS servers and compare the differences.
    3. The failed one has longer response time (8s) than the worked one (4s). (see Figure 1)
    4. If you look deeper into the failed version, there are more NBNS packages. (see Figure 2)
    5. Try disable NETBIOS one the failed server. (see Figure 3)
    6. Now everything works!

    Solution

    As mentioned previous, the solution is easy – just disable the NetBIOS from the TCP/IP seetings – WINS tab.

    After I disabled it, I tried again and now it works perfectly.
    Figure 4: It works now!
