Cannot connect from DC Slave MS Server 2012 R2 to UCS Master after AD Takeover


#1

the primary DC was joined into the UCS Master via AD Takeover.
AD entries in DNS created, so existing win + linux clients can connect without changes and new clients can join to the UCS (AD) without problems.

In the inital DC config some secondary DC´s exists. One of them should now be included in the UCS AD domain also as a backup DC (there is running a special win prog).

Starting this MS DC is no problem, because all DNS entries are copied to the UCS Master DNS.
In Tab “Server Manager” I added the UCS Master but I couldn´t connect to the UCS Master.
Error msg is “no access to the destination server”.

Any idears ?
