Windows 2008 R2 SP1 WDS Server will not start in a timely fashion

So today was interesting and it is true you learn something every day… I deployed a domain controller yesterday with DNS and WDS (Windows Deployment Service) to support my Microsoft Virtual Machine Manager 2012 deployment in the lab. However I hot an issue where the WDS server would not start, it popped up an error saying “The service did not respond to the start request in a timely fashion.” NICE!!

The event log was not much help, just giving me a Event ID 257 containing Error Information:0xFFFFFBB3

After a little head scratching, I ran the below command to disable the WDS server from listening on port 67 which is the port DHCP would use and as it is on the same computer it would cause some conflict.

wdsutil /set-server /UseDHCPPorts:No /DHCPOption60:yes

Still not luck and finally I found this blog that shows someone else hitting the same issue.

The server this is installed on is also fitting with two six core processors with hyper threading, providing 24 cores to the host OS. There appears to be a bug where the maximum number of processors is 20 before the service will not start.

To resolve:

Change the number of used processors used :

From a command prompt run the below command and reboot

bcdedit /set {current} numproc 2

Just like magic it is all up and running Smile

To revert the changes back:

bcdedit /deletevalue {current} numproc

 

Now I can continue……….

    While the article hasn’t been updated in a while, I figured I’d post this up for future googlers and the blog author to perhaps change it. Microsoft has released a hotfix for this problem:

    http://support.microsoft.com/kb/2121690

    It is not necessary to change the number of processors or disable physical CPUs in the BIOS as a workaround for this problem.
