A Windows NT primary domain controller (PDC) and a Windows NT clientcomputer reside on the same physical subnet and the same domain. The clientcomputer can connect to a network share on the PDC. In the Windows NT PDC,the following system event appears in Event Viewer:
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.
In the Windows NT client computer, the following system events appear inEvent Viewer:
Event ID: 8009 Description: The browser was unable to promote itself to master browser. The computer that currently believes it is the master browser is <PDC>.
Event ID: 8019 Description: The browser was unable to promote itself to master browser. The browser will continue to attempt to promote itself to the master browser, but will no longer log any events in Event Viewer.
This problem occurs if the subnet mask of the Windows NT client computer isincorrect or different from the PDC. The client computer attempts topromote itself to the master browser of the subnet and fails.
To correct this problem, change the TCP/IP protocol configuration to thecorrect subnet mask.
