VPN: specified domain either does not exist or could not be contacted


I have setup SSTP via Windows 2016 Essentials.
Everything works fine: connection is ok. However, when the connection is made and I try to rdp to the (domain joined) machine which is making the VPN connection, it says
"specified domain either does not exist or could not be contacted"

Please advise.

Make sure VPN DNS points only to your Corporate DNS, and for user name use  internal_domainname\Username

That's all done. Also "use default gateway on remote network" in TCP/IP settings is unselected.

Correction: filling in DNS servers did the trick!

One more thing. My Outlook sometimes pops up asking for credentials, then shows the credentials for the SSTP. Any idea what that might be (I guess something in my adaptor settings)?
Rob WilliamsCommented:
Outlook can ask for credentials for a variety of reasons, if you google there are dozens, but most often it is unable to find the server.

As for showing the SSTP credentials, and possibly why the pop up;  go to  control panel | Internet options | connections | and see if the VPN connection is in the list.  If so, I would remove it unless you want all Internet traffic directed through the VPN.
