UCS can offer Active Directory (AD) services for Windows computers. Is the network architecture drawn below correct? DNS settings are ok?
At System Diagnostics on a Slave machine:
The following KDCs were unreachable: tcp dc-site_x.office.intranet: 88, tcp dc-site_y.office.intranet: 88 etc.
samba-tool drs showrepl` returned a problem with the replication.
Inbound ‘CN=Configuration,DC=office,DC=intranet’: error during DRS replication from Default-First-Site-Name/DC-SITE_X (WERR_SEM_TIMEOUT)
Inbound ‘CN=Configuration,DC=office,DC=intranet’: error during DRS replication from Default-First-Site-Name/DC-SITE_Y (WERR_SEM_TIMEOUT)
Is VPN required between UCS Slave?
