On Friday morning and on Sunday morning this week the Windows Deployment Services service on both our SCCM servers that service PXE requests broke and stopped responding correctly to PXE requests, and also started consuming significant amounts of CPU resources on the server.
This state led to machines not receiving PXE requests when rebooted (workstations configured to NETWORK boot as first boot option), causing some machines to stall at boot,
Stalled machines rebooted while the services were broken would most likely stall again.
In both cases, restarting the WDS services while in this state restored proper service. However, I am concerned that this behaviour is going to continue to occur. Any ideas what could be causing this? This was working fine for about 2-4 months, no patches applied in last week, we running version 6.3.9600.16384 for WDS,
Any ideas will be most appreciated
Thanks in advance,
