[Samba] setting up RDS on a windows 2019 member server

[Stefan G. Weichinger]

I run a 2019 member server in a samba-domain with 2 samba-4.19.4 DCs

I have to setup Remote Desktop Services on that machine and that fails:

something around adding the broker to the management server  (error 
messages are in german, so that's a loose translation ...)

One thought is that maybe ports 80/443 were already used by some 
adressbook service: disabled that site now in IIS.

Another thought is that maybe RDS needs some DNS-entries and for some 
reason can't add these to the Samba-based DNS servers?

Does someone know more about this?

(I can only test in the next maintenance window if disabling that IIS 
site maybe already helped ... )

thanks!
Stefan
