Wireless Display stops working after joined to domain

Now there are many variables as to what could possibly cause the wireless display to stop working on your computer after joining it to a domain. Let me tell you my story about the recent encounter I had with wireless display and Group Policies.

Like I stated earlier, there are several variables as to the exact reason why wireless display stopped working after joining a computer to the domain. But in this particular case I did a lot of troubleshooting and I finally found what Group Policy Object caused wireless display to stop working. Internet Connection Sharing (ICS) was the Group Policy Object that caused wireless display to no longer work after the computer was joined to the domain.

If you read the help section of the Group Policy Object, which by the way the full path to the GPO is:
Computer Configuration > Policies > Administrative Templates > Network > Network Connections
The setting title is Prohibit use of Internet Connection Sharing on your DNS domain network set this to Not Configured or Disabled.

I had to read the Center for Internet Security (CIS) benchmark document to find out that this setting affects Miracast.

Hopefully this helps somebody!
