Strange browser issue - due to svchste.exe? (dnscache?)
« on: July 30, 2009, 01:35:52 pm »
Hello.
Just registered here, obviously.
I've made use of the configurations pages several times in the past and appreciate them very much, but for some reason never noticed there was a forum.

Anyway, I've had this problem for some time now and tried numerous things to fix it, but still haven't managed and it's very frustrating.
Hoping somebody here can help.

And I hope you don't mind me pasting a link to the main topic I've been using on another site to try to resolve this, rather than trying to accurately summarize all of it in a single post here: http://if.invisionfree.com/topic/5048415/1

The basic problem is that multiple browsers just seem to stop loading pages, as if I'd lost connection, even though other programs accessing the internet like Winamp, instant messengers, World of Warcraft, etc. are uneffected.
There is also sometimes, but not always, a corresponding CPU usage spike traced to svchost.exe - NETWORK SERVICE >> DNS Client [Dnscache]

A couple primary questions I have regarding what came up in that topic are:

1) Is it advisable for me to disable the DNS Client service to attempt to resolve my issue, and is that more like treating a symptom instead of the actual problem?

 I had disabled it to try that out before remembering and visiting this site, only to find that DNS Client is recommended to be left on even in the "Safe" configuration, so I turned it back on for now.

2) Is it advisable to "overwrite the "svchost.exe" file with the "svchost.ex_" file from the Windows Installation Disc ... via the recovery console." and if so, could anyone give a simple explanation of how to do that, especially since svchost.exe would always be in use, wouldn't it?  :-\

Any other suggestions, links, etc. would be wonderful.

And, again, thank you very much for providing this site.  :-*

DNSClient is just a local DNS cache. It can save multiple trips to the DNS server, nothing more. If you think you have a DNS cache issue, you can always clear the cache with a "ipconfig /flushdns" command.
2) Is it advisable to "overwrite the "svchost.exe" file with the "svchost.ex_" file from the Windows Installation Disc ... via the recovery console." and if so, could anyone give a simple explanation of how to do that, especially since svchost.exe would always be in use, wouldn't it?  :-\

Definitely do not mess with this file. Svchost.exe is the container file for many DLL (Dynamic Link Library) files that load as services. There can be a number of these, and each one can host multiple services. You can get a complete listing by using the command "tasklist /svc"
