14-11-2004, 12:27 AM
Hello there,

Turned my computer off for the weekend and when I arrived home iturned it on as per usual. The computers going fine, no other problems other than the dialup connection.

Basically, I connect to the net fine icon comes up. When I open up firefox/IE/IRC/MSN/FTP or anything that uses the net I get DNS errors. do a dns on anything other than the network and loopback and i get timing out msgs. My received and sent bandwidth isn't rising so the packets arent going to the big wide world.

As you can probably guess i have no idea whats going on. Can'
t say i have heard of htis problem before and definately never had it myself before.

Tried redoing the dialup connection properties, removing and readding the connection, uninstalling and even removing the modem and readding. But can't see anything out of the ordinary.

I'm honestly lost so please help so I can get my gateway back! lol
Thanks in advance,

>> Richard

P.S. OS is win2000

Grab Spybot Search & Destroy, as well as the latest AVG. Check and make sure your firewall isnt playing up.
Check Add/Remove programs for anything in there you dont recognise.

Now, Click start --> Run --> cmd
Now type:

Now, type:
ping pressf1.co.nz

Next, type:
ping pressf1.co.nz

Post back with the results

u legend :P

seems I had a DSO exploit that mustv only been activated upon a reboot (these machines rarely shutdown) looks like its an old exploit that I never patched. ( I go on the basis that using MS patches causes even more problems) and given that these are only personal boxes, patching isnt one of my highest concerns. Obviously, I don't go into porn sites and sites with applets on them unless i trust them, but my flatmate did use this computer and looking into the history, seems hes been to a few untrustworthy sites and am assuming thats where the exploit came from.

Thanks for your help, its much appreciated. Interesting, as an advanced computer user, the most simplist thing slipped my mind. Thanks again :)
