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

[Guest ThomasAJ]

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.

Tom,

Do you mean it is at 50% CPU all the time?

You could get hold of Process Monitor from sysinternals, restart the

computer, start Process Monitor and see what is happening,

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/never put the computer

to sleep. Works for me.
