Hi everyone, this is quite urgent. I have Windows 7 installed on this laptop and everytime this laptop is on, it will freeze/hang my two desktops. Event ID: 8003 Source: Browser Description: The master browser has received a server announcement from the computer <Windows NT client> that believes that it is the master browser for the domain on transport <NetBT>. The master browser is stopping or an election is being forced. The best I can find to resolve the issue is from this link. http://support.microsoft.com/default.aspx?scid=kb;en-us;135464 To stop the 8003 error messages, make sure the routers on the network are not forwarding UDP broadcasts, keeping browser elections on NetBT local to each subnet and enable WINS or lmhosts on the network for netbios name resolution. Note Switches that are configured for VLAN's (virtual segmentation) have to be configured on a per VLAN basis to prevent UDP broadcast propagation. ---- However, I have no idea what that means or what to do on my router to resolve the issue. I am running Tomato 1.25. Please help me. Thanks a lot.
