I upgraded my Netware 6.0 sp3 server to Netware OES 6.5 SP5 + a couple
patches about 9 days ago.

Ever since then the logs on my windows servers state that The Master
Browser has recieved a server announcement from the computer Server_W that
believes it is the master browser for the domain on transport NetBT_tcpip.

Why would upgrading my netware server cause this...its about once per hour
in the logs on 3 of my windows servers. And the name in the message is my
Server name plus the _W at the end of it.
