Strange Issue

[garethEds]

We are seeing a weird problem with our WDS server. This is the scenario:

 

WDS/MDT2013 running on a 2012R2 server

DHCP running on a 2008R2 server

Same IP range

Same Subnet

All going through the same 48 port switch which shows no errors.

 

My room - 27 machines. Half the room recognizes the WDS server straight away and continues into MDt2013 and onto the image (success)

 

The other half of the room refuses to do anything and instead we are getting the following:

 

(After seeing the DHCP server)

 

Downloaded WDSNBP from 10.180.8.8

 

WDSNBP started using DHCP Referral

Contacting Server: 10.180.8.8 (Gateway: 0.0.0.0)._

 

The process then fails.

 

pXE drivers are all present and correct.

 

If anyone has any ideas I would love to hear from them.

 

Regards

even though they're on the same subnet and switch, have you tried setting dhcp options 66 and 67?

Yes - they have been set on the DHCP server since Day 1. The annoying thing is that nothing has changed. Absolutely nothing. It works on 50% of the machines in my room whilst the other 50% do not. What I Have noticed is that the pXe bit is suddenly a lot slower seeing the DHCP server - but eventually it does.

Well - after spending an afternoon and most of this morning reading through things on Google I finally found the answer myself.

 

WDS was the issue. I found a list of 10 machines that were in the AD Prestaged Devices area. (Don't ask me why.... - I have no idea).Anyway I deleted them from there and BOOM the machines started rebuilding. They must have been there for a while as they were referencing an older server.

 

Crisis over.
