Hi All

We have been having intermittent issues with authentication for the last few days and I have been digging deeper into the domain controllers.

I have noticed on two of the DC's the handle count for svchost -k DcomLaunch are between 60 - 80'000 on each DC, this seems overly high.

Looking at the services on Sysinternals process Explorer tab I see this is responsible for DcomLaunch, PlugPlay and Power.

Where do I go from here to determine actually what is causing this high number.

Thanks

If it is the memory leak issue , I recommand you to use RAMMAP sysinternal tool.

It exactly shows what is consuming more memory. It might so happen that , some processes don't release the memory . You need to identify those and see the web to get the resoultion or apply hot fixes for those.

See if below link help you

check if you can restart WMI service (if there is no dependency).
