There are 4 svchost.exe( LocalServiceAndNoImpersonation) running that are causing network resources to constantly peak. What are these used for and are they need or can be turned off some where?This is a fresh install on a intel qaud core Q6600 system with 4gigs of ram.

Run Task Manager and go to the Services Tab, it will tell you. Ned Pyle [MSFT] - MS Enterprise Platforms Support - Beta Team

dnt tell me if you need it or not

Not a very good answer. LocalServiceAndNoImpersonation kills my pc for 10 to 15 minutes anytime I start or restart. I analyze the wait chain and wmpnetwk.exe is waiting on LocalServiceAndNoImpersonation. Anyone have any idea why it does this and how can it be fixed. Thanx!

here's a starting pointLocalServiceAndNoImpersonation is related to Windows 7 Media Center (networking and extenders).

....and it's probably been turned on (check Windows Media Player) and looking for network extenders. Something along these lines. You can always query the services it is relating (sc qc SrvName)

Thanks for the information. I am havng the same problem and this gives me a good starting point. You should write up your answer and submit it to Microsoft because the Tech Ned Pyle didn't have a clue as to what was going on and gave a pretty ignorant answer.

I have the same issue, after setting up xbox360 as a windows media player extender it seems the WMP service is pulling a steady 25-30mbps of traffic down via the network adaptor. Wouldn't usually be a problem, but the adaptor is actually a tether interface to my android and i'm seeiong a few mb every 10 mins being downloaded by the phone - eating up my data.... this isn't cool. What the hell is it doing?? Rob
