we have following issue on our fresh installed CU1 (Migration from Exchange 2007):
At install the creation of the edb files failed on failure:
An Active Directory error 0x51 occurred when trying to check the suitability of server <dc without gc role> Error: 'Active directory response: The LDAP server is unavailable'....
The install trys then two more times (other names for db) so that in the AD Configuration there are three entries for this second cas 2013 Server.
With the other cas which we have also installed yesterday everthing went fine. The difference between the two instalations is that the good one uses only one dc (config dc and global catalog) and the bad one has used one dc which has no gc catalog in it as config dc and the other dc as global catalog (which it has in it).
So everytime we try to finish the install process we get the error that the database doesn't exist (which is correct no folder with such edb). An error occurred while preparing to mount database 'Mailbox Database xxxx' (Active Manager)
which is the best way to get out of this miserable installation?
