Thanks Sorin, that might be a clue - all the computers are in Workgroups, 6 different ones in total. Bit silly if you ask me! The XP Home computers can't join a domain so we'll have to stick with Workgroups, but I'll maybe try them all in the same one. -----Original Message----- From: Sorin Srbu [mailto:Sorin.Srbu@xxxxxxxxxxxxx] Sent: 17 November 2003 09:45 To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Re: Windows XP causing broadcast storm on network I might have an idea. XP home uses workgroups only. I've also seen that xps in workgroups chatters incessantly to each other... Joining them to a domain quiets them down quite a bit. THis might be your problem too? HTH. --Original Message Text--- From: Kevin Alexander Date: Mon, 17 Nov 2003 09:30:38 -0000 Windows XP causing broadcast storm on network I'm hoping someone has an idea of whats causing this annoying problem! We have a 20 user Windows 2000/XP (about 50:50 mix) network that ran with no problems until someone bought in a laptop with XP Home installed. The moment it connected to the network all connections and internet connection went down. Pinging any PC on the same switch worked, but not to a different switch. Looking at the lights on each switch in the path from this laptop to the router, the lights were flashing like mad. Disconnecting the laptop got the network back within 30 seconds. We took the laptop out of the network and thought no more about it until we put some new computers in. We now have 3 XP Pro PCs and 2 XP Home laptops that are doing the same thing. They seem to set each other off - 2 of the PCs were fine for a few hours until the other connected, now any of the 3 cause the network to stop working. All systems are using DHCP from a Netgear FR114P router, which then NATs to a broadband connection. Sounds a little like a virus, but we installed Norton, with updates, and it picked up nothing. Any ideas anyone? I haven't got a traffic sniffer, but if you know of a good free one that might give some clues.
