Window Server2012 r2 joins the domain and the network and share center display "unknown"

Hi, I am currently experiencing a problem and hope to find help, as follows:

I deployed alwaysOn, and the machine environment is "window server 2012 r2". I added the machine TEST01 to the domain AD (TEST01 and AD are two different network segments)

Open the network and sharing center of my machine "TEST01", display "unknown", the service for monitoring the status is disabled

At present, I already know that opening the following two services can solve the problem:

Network Location Awareness NlaSvc

Network List Service netprofm

But even then, every time I restart the server or run for a while, it changes back to "unknown".
In response to this phenomenon, I have made the following solutions:
1. Change the above two services from the original "automatic" to "automatic (delayed start)". After restarting, it still does not work and cannot solve the problem.

2. Open domain controller AD and machine TEST01 open port 389. After restarting, it still does not work and cannot solve the problem.

3. Set the default gateway. After rebooting, it will still not work and will not solve the problem.

This problem has been bothering me for a long time, and the current alwaysOn failover will also prompt me that the server connection timed out. What should I do to solve this problem? my English is poor:(
