Client tries to connect to slave server instead of master

Hi all,

we have a master DC on one location A and a slave DC on a location B. Both are connected via (slow) VPN. Now we have a third location C which is connected to location A via another VPN and we’re trying to logon to master DC from here. Although the DNS entry of this client points to master DC the client always wants to connect to the slave DC, too (which fails since there is no VPN between B and C).

Any idea how to fix this except for adding another VPN between B and C ?

Thanks - Martin

What client OS are you running? Linux or Windows?

I‘m using Windows 10 pro.
