Problem with ICS on client

Hi, I have a strange problem that I have not been able to
find the anwser to!
To start with I have a small network of five computer in
my office that all worked fine. I am hooked up to the
internet with sattalite service.
Some one tried to hook up their lap to to my network and
when it diden't work he disconected one of my clients to
try to get it working one-on-one with the lap top.
Well he never got it working but did succeed in messing
up the client!
When ever I turn on that client the internet shuts down.
The rest of the network works just fine between my
computers here in the office, it's just the internet. The
strange thing is all I have to do to restore the internet
is unplug the computer and wal-lah, all the others work
fine.
I first tried changing my TCP/IP settings to automaticly
get the IP and that helped.... for about ten min. then it
went down again. Then I changed it to a static IP that I
first made sure wasn't on any of the other clients. Same
thing. It will run for about ten min just fine and then..
kaput. Down again. I am not getting any error messages
like "IP conflict" or any thing of that sort. It just
says "DNS Lookup error" on my browser and the internet
stops working.
I am running XP Home on both systems.
This has been realy frustrating, I hope someone can help
me!
Thanks a lot, Jacob Bushnell
 
You will need to provide a little more info about how your network is set
up. Do you use ICS to share the satellite connection? If so, is ICS
configured on the client machine that breaks the network? If that is also
the case, disable ICS on the client machine (you can only have one ICS
server running on a particular network) and that should fix your problem.
If not, keep answering questions:

Does the client machine have more than one connection in the network
connections folder?
Are there any event log messages in the event log of either the client or
the ICS computer sharing the satellite connection (if there is one)?
Can you include the results of "ipconfig /all" from the computer sharing
your internet connection (if there is one), the computer that breaks the
internet connection when it is connected, and from a different client
computer both when the network is broken and when it works?

I think the error message is telling you where the problem is. It sure
sounds like a DNS lookup error. I suggest looking at the DNS settings for a
good machine and the rogue one. If different, set the rogue the same as the
good ones.

Good luck.

Click to expand...

I've seen the same behavior when a computer was infected with the
Blaster worm, which your computer might have picked up from the other
person's computer.

Run this Blaster removal tool:

If that doesn't solve the problem, run a full antivirus scan and run a
spyware remover such as AdAware or Spybot Serach and Destroy.
