Windows 2000 server kills the network

[Guest]

Hi, this is my problem

We have 5 machines (2 win xp pro and 2 MACs) connected to the internet in
the office via biteport router (covad), the router is managing the DHCP and
all works just fine. Now im adding an extra machine with windows 2000 server
as the OS because I want to use that as my staging server for our websites
whe have hosted in a dedicated server we have in texas.

Every time I connect the windows 2000 server to the network, in mather of 4
or 5 minutes the whole network gets killed, all the machines, including the
server 2000 lost the connection to the internet. I have to unplug the server
from the network and manually reset the router to have all up and running
again

I dont want the server to manage the DHCP because I'll be restarting it
several times during the day (it will be a staging server). The DHCP
managares is no installed. I've assigned the ip manually to test it and
didn't worked

I dont know what to do

I'll appeciate any help

mmmmmmm;

I got the same once with a laptop.
Look with a networkprogram like Ethereal to the networktraffic and see if
the server is trying to connect a website on internet. It is probably a
backdoor-virus. I finaly found it by scanning the laptop online with
Trendmicro. But could only remove it with Hijackthis. The virus was trying
very fast to connect a site called greekpimp and was also asking on network
who has some ip-address many times per second. That was why the router frooze
up.

Good luck.
