MS DNS servers are out of sync, and the following errors can be found in POA Agent logs (C:\Program Files\SWsoft\PEM\Logs): [14/07/07 19:35:25] DEBUG: PEM_PleskD:
[processHostOps/.\HCLProcessor\Win32\HCLtoMPF.cpp:273] Thread (3780) Mpf error
response (Invalid pointer [<response><errorContext description="Object
reference not set to an instance of an object." code="0x80004003"
executeSeqNo="1"><errorSource namespace="DNSManager"


Such issues can arise when the WMI infrastructure of the MS DNS server is broken.


As a workaround, one can do the following:1. Log in to the failed MS DNS server
2. cd %windir%\system32\wbem
2. For %i in (*.dll), do RegSvr32 /s %i
3. Restart "Windows Management Instrumentation" (winmgmt) service
These steps should repair the WMI infrastructure.
