msm 765 AD Join

[Neonium]

I have a msm 765 (5.7.0.3-11516). I did try to bring in a 2008 Domain. I always get the error message ERROR: Unknown domain. (149)
I do not know what I'm doing a mistake. As an example test.test-company.de

Domain NetBIOS name: test
Windows Domain: test-company.de
Check Active Directory access with attribute: Disable

user: username
password: password

Where is the mistake?
