W2K server broadcast proble!!!

[bigdan]

First of all note that i'm a newbie to W2K...

I recently install W2K server on a IBM PC for a web and ftp server.

My problem is that after a period of time or after a request on ftp or http, my server initiate a bunch of http connection ( like he is broadcasting) and my router is shutting down the WAN port.
I have installed a sniffer and the protocol is HTTP.

What can cause this?

The only services that I installed are IIS (ftp and web) and active directory.

Any help will be very appreciate.

Thanks

Dan

Check your DNS settings, esp. forwarding and lookup zones.
