    Hi all,

    My office network was knocked out of action today for about an hour. For some reason one of my XP Pro workstations 'THREE' sent a 'server announcement' over the network thinking it(workstation 'three') was the 'Master Browser? My Win2k Server should be the master browser! thinks were running so smooth too!!! errgggg!!!

    Here is the System log entry from my win2k Server: (MrxSmb - event 8003) "The master browser has received a server announcement from the computer THREE that believes that it is the master browser for the domain on transport NeBT_Tcpip_{F86F96321-C90E-49DB-99A}. The master browser is stopping or an election is being forced."

    My staff said all of the sudden the network just went down all at once. NOBODY WAS EVEN WORKING ON WORKSTATION "THREE" which appears to be the culprit??

    My server is isolated from the workstations and runs off a different hub which is 'uplinked' to the main hub. I originally thought that the server’s hub went out cause initially all the workstations could see each other (but not connect to each other) but I could not see/ping the server from any of the workstations. When I got on the server, I could not see/ping any of the work stations. A simple restart of the server did NOT work.

    I had to physically shut off all workstations, the server, and even unplug the power supply to the hubs, and then start things up in order: Server, Client "one", "two" etc. Finally I was back up.

    Any ideas why workstation 'THREE' sent out such a message? How do I prevent this from happening again? I done a google search and found only a few articles on this type of error.

    Any Help is, as always, greatly appreciated.

    i looked up your error at www.eventid.net. you should check out the site. click the "search events" item at the top of the page. enter your event id number(8003) and the source(MrxSmb). it gives you a registry fix for your problem. do it on all your machines EXCEPT your server.

    hope this helps
