Cannot join UCS server to Existing Windows Domain

UCS - Univention Corporate Server
#1

Hi All,

I am new to UCS and I am trying to join this server th an existing Windows Domain. It’s a fresh install and I have never run UCS in the past.

It’s my intent to set this server up as a Member domain controller for my existing domain, but I assumed step 1 would be just getting it joined to the domain in the first place.

I run the setup, get to the initial setup screen, select to join an existing Windows Domain, and get the following error:

Internal server error during "setup/check/join_info (wizard)".
Request: setup/check/join_info (wizard)

I’m really not sure what to do from here because I cannot progress beyond this point. Normally I would set up a DNS entry and and AD object for the system ahead of time, and then try to join, but at this point in the UCS setup process I have not even yet been able to set a hostname.

Any help out there for me? This is pretty much out of the box setup and not working for me.

Thanks!

I had the same error when trying to install from vmware image.
Install from the ISO and use manual network setting, point to DNS of the AD and it should work.
Posting this just incase someone encounters the same problem.
