PXE boot not working in esxi 5.x VM

[mauser_]

Hello, i am having trouble with pxe-boot from a ESXI 5.x VM  (see this thread http://social.technet.microsoft.com/Forums/windowsserver/en-US/8199270a-b833-4063-9b8d-b88baf135a88/... )

Problem occurs NOT on physical-hardware but only in an esxi 5.5 VM.

I think there is something with TFTP/Variable Extension Windows from WDS that is not working correct in esxi.

What can be done to fix this?

Thx

Hi,

i am not sure if that has something to do with your issue, but check the following Microsoft kb.

"TFTP download failed" error message during a PXE boot on a client computer that connects...

Hi,

i have tried this already without result.

I do remember some option in registry in the WDS server about UDP portpolicy when I was working on a similar TFTP failed error message in one of my server.

Ah. here it is:

Just to make sure that you DO know what you are doing with registry

Hi,

i have checked your option.

UDPportpolicy is default on "0" in server2012R2.

So this isn`t the solution...

I am having similar issues with esxi 6, (Server 2012 and PXE boot not working)

I have set it up PXE with WDS, on a physical server (Server 2012) and I have no issue.  So it seems the issue is with the VM.

I have tried the E1000 driver with no luck.  Did you ever get this resolved?
