having problems with svchost 2

[takethapowerback]

hey guys, anyone ever heard of of a svchost error? About half the people in my department are getting it. It wont let you copy or paste and it takes forever to log on. Anyone know any solutions to this problem? We know what caused the problem, its a program called Webshots, Im sure most of you have heard of it, anyways......we uninstalled it and we still get the same error. I have replaced the svchost file with one that wasnt corrupted and it still gave the error. if anyone has any ideas it would be much appreciated.Thanks in advance.........

Usually occurs because of stack corruption. Problem should've been fixed with older SP1. Try latest Service Pack install. I'll check into this a bit more... please post if successful or w/ more information so that i might either continue or move on. Hope this helps. -md

Thanks....but I tried both service packs and still didnt fix it. Its up to you if you would like to research it more but it looks like Im just going to have to start reformating PC's till I figure this out cause I have people who arent able to get any work done. Its only 10 users so it shouldnt take to long, but I still would like to know how to fix it if it ever happens again....Thanks for your time.

SUMMARY
Svchost.exe is a generic host process name for services that are run from dynamic-link libraries (DLLs). The Svchost.exe file is located in the %SystemRoot%\System32 folder. At startup, Svchost.exe checks the services portion of the registry to construct a list of services that it needs to load. There can be multiple instances of Svchost.exe running at the same time. Each Svchost.exe session can contain a grouping of services, so that separate services can be run depending on how and where Svchost.exe is started. This allows for better control and debugging.

Svchost.exe groups are identified in the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Svchost
Each value under this key represents a separate Svchost group and is displayed as a separate instance when you are viewing active processes. Each value is a REG_MULTI_SZ value and contains the services that run under that Svchost group. Each Svchost group can contain one or more service_names extracted from the following registry key, whose Parameters key contains a ServiceDLL value:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Service



MORE INFORMATION
