Error Event ID 8003 Source MRxSmb

[Jmann]

We are running windows 2000 ad. One of the workstations
is causing an error in the events log. It just recently
began. The error indicates that workstation is attempting
to become a master browser.

 

[Tom Ausburne]

If a Windows domain spans more than one subnet and the TCP/IP
protocol (NetBT) is used, each subnet will have a Master Browser. If
a Master Browser receives server announcements from another computer,
claiming to be a Master Browser, an election is forced to ensure that
there is only one Master Browser per subnet. These browser elections
cause the 8003 message to be recorded.

If the routers on the network are configured to forward UDP
broadcasts to UDP ports 137 and 138, then the election broadcasts
that are intended to remain in the subnet are forwarded to other
subnets.

This problem also may occur if the subnet mask of the client computer
is incorrect or different from the DC. The client computer attempts
to promote itself to the master browser of the subnet and fails.
