DNS lookup very slow

Hi. When I try to open any new page, it takes forever for IE 6 to look up a
domain name. Eventually it resolves it, and I can surf fast within a
particular domain. But when I want to switch to another one - its slow again.
Example: 1st: www.google.com - slow
2nd www.google.com/smthing - fast
3rd www.yahoo.com - slow

Any suggestions how to resolve it?
Jim
 
Try this - go to Start...Programs...Accessories...Command prompt.
Type in "ipconfig /flushdns" (no quotes), hit Enter.

If no joy, then contact your ISP to see if they are having any problem with
their DNS servers. I've run into this problem intermittently, albeit
rarely, with Road Runner sometimes. In those instances, I temporarily
switch to alternative DNS servers.

If still no joy:

This may be caused by spyware/malware that's gotten installed on
your system. Use Ad-Aware, MSAS and/or Spybot Search & Destroy to remove
it.

Microsoft Anti-Spyware (beta)

Ad-Aware: http://www.lavasoftusa.com/
Spybot: http://www.safer-networking.org/en/index.html
Good sites on how to install and use Spybot -

Also download a winsock repair tool, to have just in case cleaning up
anything found breaks it -

Winsock repair tools:
LSPFix- all versions of Windows http://www.cexx.org/lspfix.zip
Winsock2 Fix- Win98, ME
http://www.bu.edu/pcsc/internetaccess/winsock2fix.html
LavaSoft- all versions of Windows-

More information here:
http://www.spywareinfo.com/
http://inetexplorer.mvps.org/Darnit.html
http://www.doxdesk.com/parasite/ - runs a little script when loading page to
check for common parasites

If no joy, in IE go to Tools...Internet Options...Advanced tab, Browsing
section, uncheck "Enable third-party browser extensions", click Apply, click
Okay, reboot. If that solves your problem, then more troubleshooting is
needed to find out exactly which program, or Browser Helper Object (BHO) is
causing this problem. You don't want to leave it at that, as some BHOs are
useful or necessary - like Adobe Acrobat for reading .pdf files or an
essential component of Norton AV. Get BHODemon -
http://www.definitivesolutions.com/bhodemon.htm - read all about BHOs.
Disable all items, and then gradually replace one or two at a time to narrow
down the culprit.

Or if you have IE 6 SP-2 you can do this within the browser:

If all the above fails, then the problem could be something new that the
spyware cleaners above don't have in their databases yet. In that case....

Thanks. Tried everything didnt work. One piece of info I forgot to mention:
Netscape and ALL other browsers like Firefox, work perfectly fine!
And it stoped working AS SOON AS I installed SP2.
Do u know why this problem is so special to IE 6.0?
 
Do you have a network running by any chance? I have the same problem
and it appears that IE6 is looking everywhere for the page including the
machine on the network. I haven't been able to fix it either and now
use Firefox as my default browser.
Cheers,
Larry

Try deleting your TIF and History files completely:
http://www.mvps.org/winhelp2002/delcache.htm

If no joy, then with this problem being associated with SP-2, I would
suspect a third-party issue - such as a BHO or malware. Did you go though
all the malware cleaning steps I suggested? Did you run HJT and post a log
to one of the expert forums for analysis?
 
Yes i ran all the programs Jon recommended. Moreover I also deleted all the
history, cookies and off line files.
Any other suggestions guys? What is a difference between ALL other browsers
and IE6? why all others work?
