I run Win98se and I woke up to this:
whenever I try to run any application or internet browser othet than IE I get this message -
"Windows cannot find svchost.exe. This program is needed for opening files of type 'Application'". I ran two full on-line virus scans - I still suffer. Can't run 'regedit' nor 'msconfig'. After the boot Windows calls for missing 'SMSSxe.exe' and then serves me the message about 'svchost.exe'. I am stuck!
Any Ideas how to fix this?
Thanks.

i keep getting this warning pop up the last few days>> "generic host process for win32 services (svchost) is being contacted
from a remote machine 172.16.5.188 using local port 135 EPMAP location
service dynamically assign ports for RPC do you want to allow this
program to access the network" what does this mean, is someone trying to attack my computer?

Probably. It's probably someone who's infected with a virus and doesn't even know it's going on.

Guess there are many instances of this svchost.exe problem

bought a TV capture card. installed software.
after i log off, svchost.exe consumes 95% CPU.
doesnt consume CPU when i restart the system. only after i log off.

Followed instructions from this website:
windows xp home, so no tasklist. Installed ProcessXP. Noticed that the one of the svchost.exe is consuming the resource. The service tab shows only the RPCSS service.

Installed the patch from one of leo's links to microsoft. Ran Antivirus, Spyware and Ad-aware.Nothing useful.

Uninstalled the TV card software, didnt have the problem. Installed the software again, log off and logged in. The problem is just there.

Thanks for any ideas how to solve.

should I go for XP sp2 but I dont want to install it now after all the reviews, all remaining updates have been installed.

Click Start on the Windows taskbar, and then click Run.
In the Open box, type CMD, and then press ENTER.
Type Tasklist /SVC, and then press ENTER.
Try this

Hi, one of the system svchost.exe's on my computer is using a very large amount of memory. In addition, my computer can't connect to the internet but when I connect the ethernet cable to the computer it detects it. The taskbar is also not loading properly and explorer keeps freezing. What do I do?

I disabled the SSDP (might have spelled it wrong) service that other people mentioned. Explorer now loads properly but I still can't access the internet. Any suggestions?

Leo - Great job of explaining svchost, but unfortunately I think this service may be negatively impacted by xp sp2. I've installed sp2 7 times, from both the download and from the MS CD, and the results are always the same. The computer takes 10 minutes to boot, and then you wait 3 minutes every time you push a button (My Computer, Word, etc.). I can immediately gain my lost speed by using Task Manager to delete the second listing of svchost (Network Service). Unfortunately, this soon generates a RPC error and shutdown. This second listing of this file doesn't appear in sp1, only after installing sp2. Disabling the sp2 Security Center doesn't help. Microsoft's canned response is "you have a worm". Norton Anti-Virus 2004 (definitions up to date, MS's own Blaster removal tool, and Symantec's own stand alone
Blaster removal tool all say I don't. I'm not the only person who has installed sp2 to experience this problem. Aside from waiting for sp3, do you have any suggestions? Thanks

My first reaction is that perhaps you are not behind a firewall, and are under attack from the outside. It's hard to say, though. I did Google for "SP2 slowdown" and there are several instances, some which might apply to your situation.
