About every hour or so, 99% of our servers are
disappearing out of Network Neighborhood. By rebooting our DC with PDC emulator FSMO,(we still call it the PDC) the following is logged in system log:
Event ID: 8015
The browser has forced an election on network
\Device\NetBT_Tcpip_{F14D830F-DA96-4858-99EE-DE2ECD13648C}
because a Windows 2000 Server (or domain master) browser
is started.
It appears that another device is assuming domain browsing responsabilites away from the PDC even though it is still up and functional, but I may be wrong. There is no event message stating that the PDC has lost domain browsing rights. Again, a reboot of the PDC temporarily fixes the
problem, and generates the above event.
This has just started recently, over the past few days.The only thing I can think of that has changed, is the decommission of a DC that was a WINS and DNS server, and a recommision of a DC on new hardware, and an update of remaining servers to sp4.
Info:
Flat LAN, no routing
Win2k AD Native mode
14 DC’s
All servers(DC and member)are Win2k sp4, or Win2k Adv server sp4. One WinNT4.0 server sp6
hub/spoke WINS topology
PDC is hub, with 7 subordinates in a push/pull replication with the pdc only. They do not rep with each other.
Help!! this is really frustrating.
