Default svchost.exe

Hallo, this is the problem I have: at every Windows start, when I try to launch eMule it doesn't appear, but emule.exe starts and I can see it in Task Manager. Such situation may last even 2-3 hours.

I notice a svchost.exe [PID 1896, but it can be 1900 or other] blocked on 23-25% of CPU usage: if I terminate this process, eMule appears in a few seconds, but audio doesn't work anymore (I can hear only Windows sounds, not audio files like mp3s and waves; I can watch Avi files but not hear any sound).

I prompted TASKLIST /SVC and these are the Services running under PID 1896:

AudioSrv, BITS, Browser, CryptSvc, Dhcp, dmserver, ERSvc, EventSystem, FastUserSwitchingCompatibility, helpsvc, HidServ, LanmanServer, lanmanworkstation, Netman, Nla, RasAuto, RasMan, Schedule, seclogon, SENS, SharedAccess, ShellHWDetection, srservice, TapiSrv, Themes, TrkWks, W32Time, winmgmt, wscsvc, wuauserv, wzcsvc

Is there a way to kill these services one by one, so I can identify the problem without killing the entire Svchost?

Greetings from Italy ;-)

Hi, does anyone have a fix or troubleshooting option for the svchost.exe
application? It sometimes goes crazy on some systems and takes up the CPU's
resources, both network and system can keep the processor maxed. This
application appears to have something to do with IE.

SVCHOST is a Windows system component that acts as the "host" for
running a large number of services. It is normal to have 5 or 6
instances of it running.

It is possible that some malware item has infested your computer and
is running as a service under SVCHOST. In order to diagnose this
further you need to do some investigation:

1. If you are running XP Home edition then you need to download the
TASKLIST utility from
http://www.xmission.com/~comphope/download/winxp.htm
and install it. TASKLIST is included with XP Pro.

2. Bring up the Windows Task Manager (Ctrl+Shift+Esc) and go to the
processes tab. Identify the PID number of the SVCHOST instance that
has the high CPU usage and make note of it. If you click twice on the
CPU column header the list will sorted based on CPU usage with the
highest usage at the top.

3. Open a Command Prompt window and enter the following command:

TASKLIST /SVC

Locate the problem instance of SVCHOST by its PID number and make note
of the names of the individual services that are running under that
specific instance of SVCHOST. Post those names back here.

Good luck

Hi, Ron, I assume that the steps are different for XP Professional?

Hi
Take a look at your hard drive if you clicked on the link that is on my page
you probably already downloaded it.
Look for a file, ProcessExplorer.zip unzip it and run the exe file.
Otherwise, here you go,
