WDS - 2012 R2 Standalone - Client Fails to Initialise

I have a small environment with 1 physical server running 2012 R2 and WDS with DNS and DHCP, there is no AD in the environment, WDS is configured as Standalone.

If I create a VM on the physical server using Hyper-V, I can PXE boot and install my image with no issues.

If I try the same on any on the other physical servers I get the following message:

Note: DNS resolution from the PXE (PE) environment seems to be working correctly and I can ping the server by hostname and FQDN.

Here is a copy of the error log:

I have also tried disabling the windows firewall as well as putting in an any/any rule but it has made no difference.

Any suggestions on the cause?  Could it be RPC related?

Thanks
