Re: There are currently no logon servers available by Meinolf

Hello Ovidio B.,

To have logon functionality you need a Global catalog server available. So
if DC1 is down and DC2 is no GC, which i assume, then nobody can logon. Make
DC2 GC and also if not done i would use Active directory integrated zones.
Also the clients ofcourse need both DNS server ip addresses in the NIC config.

Best regards
