DirectAccess 2016 problem with MSRA.EXE for DirectAcces Client

Hello

I installed DirectAccess 2016 in the dmz, with just a network card.

Almost everything is functional except the MSRA.exe command.

Let me explain:

When I try to offer remote assistance on a laptop that is in our infrastructure (AD) everything works fine. When the customer connects from home and I have to offer remote assistance to troubleshoot it does not work, there is a time out.

To work around this problem and for the moment, I have to go into the DNS server, removed the DNS entry corresponding to the ip address of the IPv4 client's laptop. Then I ask the client to restart his laptop. Once restart
I go back to the DNS and make sure the entry is in IPv6. From now on it works, the MSRA.exe command works and I can do my thing on the laptop.

On the other hand, when the client comes back with his laptop in our infrastructure, and if I have to offer him assistance remotely, I must first remove the IPv6 entry in the DNS server, then asked the client to restart his laptop. Once done, I make sure the entry into the DNS server is IPv4 and the offer of remote assistance works.

How can I fix this problem? Is it a DNS problem or a bad configuration of DirectAccess?


Thank you in advance
