First CPPM Server Error joining Domain

I have stood-up our first CPPM VM server and it is up and running, on the network, and pulled down all updates and patches.

 

When I attempt to add it to my domain, I receive the following error:

 

Failed to join domain: failed to lookup DC info for domain
'ROCKWALL.GENESTA.COM' over rpc: NT_STATUS_CONNECTION_RESET
INFO - Restoring smb configuration
INFO - Restoring krb5 configuration file
INFO - Deleting domain directories for 'ROCKWALL'
ERROR - CP01 failed to join the domain ROCKWALL.GENESTA.COM with
domain controller as dc02.rockwall.genesta.com

Join domain failed

 

The DNS server is correctly configured and I am using either my account, which is an Enterprise Admin account or the domain administrator account.

 

I cannot find any info on this error and I am at a lost at this point. Please Help!

Are the appropriate firewall ports open between ClearPass and your domain controllers? 

Also try using your FQUN instead of just the username. 


Thanks,

Re: First CPPM Server Error joining Domain

My ClearPass resides on the same subnet as my DC, so firewalls are not an issue there.

 

I am using my username@domain as I read in the instructions.

Can you try pointing it at a different domain controller?

Re: First CPPM Server Error joining Domain

I would have to stand another one up on my network as that is my only Domain Controller at this point.

 

Do you have any ideas what that error is?

Is the time set correctly? You might want to set NTP to use the domain controller.

Hello!

Have you find a solution for the problem?  I have this problem too.  We trying to change our AD server.  Then I leave the old one and I'm not able to join the new server.

THanks
