Slowing over time PXE boot to WDS Server 2012 r2

Absolute mess of a setup.
WDS services on physical Server 2012 R2 inplace upgrade from Server 2008 R2.
DHCP and DNS services on a Server 08 R2 Hyper-V guest.
Same network, same subnet.
Symptom: PXE boot to Windows boot manager menu slow, gets slower over time. Leasing of DHCP address by client in PXE environment slow, contacting WDS server takes forever. After starting an install image after going through the windows boot manager session errors will randomly kill the install process.

Tried restarting WDS services and the entire WDS 2012 r2 server, this makes no improvement.
Restarting the 2008 r2 Hyper-V guest server running DHCP and DNS make no improvement.
The only thing that makes an improvement is restarting the entire 2008r2 Hyper-V Host server. - Why?
After this I get about a day of super fast PXE boot into WDS performance. No session errors. Network copying down/up is super fast at all times, even when PXE is slow.

I went through the steps to enable tracing logs on the 2012 r2 WDS server here: enable-logging-windows-deployment-service




Nothing show up in the tracing directory though.

I do have some data in the event logs.

I'm just not sure where to start troubleshooting since I can't even seem to get tracing logging working. There are plenty of errors in the event viewer though.

Any help or direction will be appreciated.

Hi ,

For slow performance issue, we need to trace and monitor logs to analyze the cause. Tool such as Network Monitor and Process Monitor can be considered .However, analysis of log is beyond our forum support level and due to forum security policy, we have no such channel to collect user log information. So we recommend you open a case with MS Professional tech support service, they will help you open a phone or email case to Microsoft, so that you would get a technical support on a one-to-one basis while ensuring private information.
