domainwindows-server-2012
I’ve just installed a Windows 2012 server for the first time, and would like it to join our Univention Corporate Server domain, so we have the same LDAP users as on all systems.
The error message (translated – unfortunately, the install CD did not permit switching the language to English) roughly said that the domain was unavailable / not found.
We’re running Univention 3.2 currently.
"The server currently has IIS8, MySQL (both can not be removed), Sharepoint, TFS, and the Project 2012 Plugin. The Idea is to run an exchange server on this server and to run an exchange you need IIS, MsSQL and a DC."
That's definitely the wrongest possible approach to a domain controller, which should be this and nothing else. Infrastructure roles (DNS, DHCP) are ok, but web services (and especialy SharePoint and Exchange, which assume to have full control of a the server) are totally not ok.
I strongly advise against installing all of this on a DC.
If you really want to go down this route, you should first promote the (empty) server to DC, and only later install anythjing else. Installing lots of things on a server and then attempt a DC promotion is a recipe for disaster.
By default Windows Server 2012 R2 doesn't show a language bar, it shows an indicator in the tray area:
You change between input languages by pressing WIN+Spacebar. If you want to get rid of the indicator do the following:
Taskbar tab click Customize...Turn system icons on or off link.Input Indicator to Off:

I hadn't heard of Univention before. It looks like it's a distribution of Linux and Samba with some "baked-in" management tools.
It looks like you can install either Samba 3 or Samba 4 (per this screenshot. There appear to be known issues with Windows Server 2012 joining a Samba 3 domain, so that may be your problem.
I'd compare the DNS settings on the Windows Server 2012 machine to a known-working machine. DNS problems are typically the cause of issues joining Active Directory domains. If you haven't, work through the domain join troubleshooting document from Univention.
Edit:
In a Samba 3 environment, which emulates a Windows NT domain environment, a couple of defaults in Windows Server 2008 (and newer) need to be changed. The following registry merge changes the default behavior to allow for joining an NT-style domain:
