Win 2003 SP 2 DC, running DHCP for 6 months, today DHCP suddenly stopped working and none of my XP workstations can obtain an IP with DHCP. If I go into DHCP it indicates that it is NOT CONNECTED. In the Event viewer I see errors with MRxSmb event id 8003, saying that a workstation believes it is the master browser. I've since taken 3 of these workstations offline and another just takes it's place as soon as I re boot my DC. What on earth could be going on? I'm totally stumped. Thanks.
