Performance Issue - 'NT Kernel & System' using 50% CPU

Discussion in 'Windows Home Server' started by ThomasAJ, Mar 15, 2009.

    Server 2008
    In Task Manager: Image Name = System, User Name = SYSTEM, Description =
    NT Kernel & System.

    So I have had a hunt around using Google but very little info.

    A thread in Experts Exchange said to right-click on the process and then
    Properties for more details. Have done so but Proprties does not pop up.

    Not all the time but it went on for at least half an hour while I was
    watching it and hoping it would disappear so I posted the question - it did
    eventually.

    I am also seeing this process running on my computer with suspicious
    behaviour. I run a bandwidth monitor program so that I can watch how
    much ISP bandwidth is being used since my ISP degrades my bandwidth rate
    if I exceed a certain monthly limit. A number of times I have seen the
    bandwidth monitor showing large transfers in progress when the computer
    should be idle. On Windows Vista I then run perfmon (which comes with
    Vista) which will show the system cpu, disk, network, etc. utilization,
    and which will show the processes using the network utilization and the
    addresses they are transferring to. The NT Kernel & System process is
    always the one doing the transfer, and it has connections to addresses
    outside my local subnet, and it also has connections to other computers
    in my house and is actively transfering data between the computers. I
    don't have any programs running which should be transfering data between
    my computers that I know about. This seems very much like a virus and/or
    spyware spreading itself.

    I had the same problem. Surprisingly I pressed "End process" and now it
    is ok!

    I had the same problem after I put the computer to sleep, after I woke
    it up the processor was going at 56% Going into Task manager and
    ending process did not work. So I don't put it to sleep or lower-power
    state. It works for me. Also I have set the computer not to go into
    sleep automatically. Control panel/power options ever put the computer
    to sleep. Works for me.
