WDS PXE issue: PXE-E16: No offer received

作者: lesca 分类: Windows 发布时间: 2016-12-25 21:16

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 configured 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“.

My network environment is simple: the two VMs are connected via vSwitch only, no VLAN tag. If your situation is similar to mine, please move on.

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 on the failed server. (see Figure 3)
  6. Now everything works!

Figure 1: Compare the two versions of packages

Figure 2: Many NBNS packages


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!

    1 待测机器两个网口现象一样
    2 IPV4可以正常启动,IPV6不行
    3 提示PXE-E16:NO offer received;或者PXE-99:Unexpected network error.
    4 Server端选择Disable NetBIOS over TCP/IP问题没有解决。
