Hello:

Hoping someone can help. I have a desktop PC running Windows 2000 and IE 6.0. I also have a laptop computer, and both are connected to the Internet via a Netgear router and Motorola cable modem (Comcast is my ISP).

I have no problem getting on the net and staying connected using my laptop. My destkop, however, is a different matter. I can get online and stay online for 1-5 minutes and then ulimately my connection gets dropped and/or I can access any pages. My workaround is to reboot the desktop PC and I always get back online, but again, for a few minutes only.

The error message is this (when I right the properties:
res://C:\WINNT\system32\shdoclc.dll/dnserror.htm#URL

1) I have bypassed the router with both computers and get the same result: consistent connectivity with my laptop and consistent drop off with my desktop.

2) I have ruled out bad cable wires and ports.

3) I have used Ad-Aware SE, AdAware Spy and PC MightyMax.

I just downloaded and used HiJackThis (incidently, I couldn't download the program from my desktop PC...kept getting 'page could not be found' error), and ran it. Here is the log file:

Hi DC. Welcome to GTG. <_<

You may wish to print out a copy of these instructions to follow while you complete this procedure.

Please save Hijack This in a permanent folder (i.e. C:\HJT). This ensures backups are saved and accessible.

Please go offline, close all browsers and any open Windows, making sure that only HijackThis is open. Scan and when it finishes, put an X in the boxes, only next to these following items, then click fix checked.

-> When finished, mark everything for removal and get rid of it. (Right-click the window and choose Select All from the drop down menu and click Next).

Please delete your temporary files by deleting all files and folders that are in those folders (do not delete the temp folder itself) like for example
C:\WINDOWS\Temp\
C:\Temp\
C:\Documents and Settings\username\Local Settings\Temp\
Also delete your Temporary Internet Files, be sure to also select delete all offline content.
