Re: master Brwser



Event ID 8003
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.

Explanation.
The message usually means that some machine can't see the master browser, so
it tries to force an election.

Possible causes (typical problems causing this):
a) Multihomed Windows machines, such as domain controllers and RRAS servers.
b) Routers on the network are configured to forward UDP broadcasts.
c) IP subnet masks are not consistently set on all the systems on the
subnet/network i.e. there is more than one logical IP subnet sharing one
physical subnet. This is common on networks that use DHCP superscopes.
Subnet mask on problem machine must be verified to be the same as the the
subnet mask on the PDC/PDC emulator. Browsing is based on IP subnets, and
the server and the clients need to have the same subnet mask.
d) Incorrect static WINS entries. Ensure the entries for the 1B domain name,
the PDC's NetBIOS name, and the subnet master browser's NetBIOS name are
correct and consistent on all WINS servers on the network.
e) Switching configuration issues. i.e. switches should be consistently set
to full-duplex but not half-duplex. Additionally all clients should be set
at that consistent with the switch, either full-duplex or Auto.
