Hello,

I have a problem with the network in my office. The problem has just
started in the last few days. Before that it has been working fine for
months.

I have about 10 machines .. all xp and one 2000 server.
Netgear Router and Netgear Switch.

The problem is whenever I plug the switch with all the computers on it
into the Router the internet connection slows down to almost a halt.
It still resolves names but it runs about like a 56k modem.

Whenever I unplug the network switch and plug a computer directly into
the router it is very fast again. I have treid narrowing it down to
one pc causing the problem but have not had much luck. I can reset
everything and for a while and it will run fast. But then after a bit
traffic on the switch goes nuts (activity lights blinking like crazy).

I thought I had found a machine with a NIC blowing packets and
disabled that card but about an hour later it started again.

Any Suggestions on what could be causing this? I am stumped.

No new software or equipment has been installed lately so I am not
sure what else to look for.

Thanks For any Help you can give me!

How many nics in the server? Does the ipconfig/all from the clients show
that everything is pointing to the server-IP?
Does DNS point to the server-IP as well?

There is just one nic in the server..

The netgear router does dns and dhcp .. it is turned off on the 2000
server....

Let the server do the DNS and DHCP-serving. Will make life much easier for
you.
