Windows Server 2008 – How to Fix Event Id:8003 The Master Browser Error

windows-event-logwindows-server-2008

I receive the following error on Windows Server 2008 the last a few days.

event id 8003

The master browser has received a server announcement from the 
computer computername      that believes that it is the master 
browser for the domain on transport 
NetBT_Tcpip_{DE9119B3-7798-4ACB-9D0A-7CBFBBB471E6}.
The master browser is stopping or an election is being forced.

Has anyone encountered this?

cheers,

I'd investigate the computer named in the event for failing network connectivity or bad network drivers. This has occurred, in my experience, when a single computer or portion of a network is being temporarily disconnected from the rest of the network repeatedly. The isolated computer or segments performs a browser election while disconnected, then causes these events to be generated when it subsequently becomes reconnected and the master browser announcements are "seen" by the real master browser.
