Hi,

I had a fresh win2k Pro. I accessed the internet only this morning. i
was checking Reuters news site and oops my laptop shut down.


i thought the reason was windows automatic update installation. on the

evening, i used my laptop again, using google searching for answers to
some of my problem. Surprisingly, the access got extremely slow. it got

worse as the time went on. i typed netstat -n and for my surprise i
found a high number of requests sent from my laptop to neighbouring
computers.


How this can happen and how to cure it?
i have not downloaded any file and was not browing any suspicious site



any help to inspect the problem and how to cure it


i have used spydoctor and did not find anything


many thanks
 
Did you have a firewall installed and configured before you went on the
internet? It sounds like you got infected with virus or worms. Without
proper protection an unpatched Windows 2000 can be infected within
minutes of connecting to the internet. You need at least these patches:

You didn't tell us which service pack you have installed but you should
install SP4 if it isn't already installed.

Many thanks for your reply. I had installed SP4. I am surprised to see
my laptop affected while browing safe sites
 
What is a "high number" of requests? Do you recognize the IPs that the
requests were sent to? A PC is supposed to communicate on the network.

An unpatched Windows 2000 can be infected just being connected to the
internet, you absolutely need a firewall and have the installation fully
patched. Run an Antivirus scan on the machine. If you don't have AV
software installed I suggest that you do an online scan or an offline
scan by slaving the disk in another Windows 2000/XP machine or scan it
over a network. Installing Antivirus software when virus are already
present is a bad idea. You can try this:

Symantec Security Check

Other major AV suppliers have similar sites.
