For troubleshooting, group policy results may be useful.

For Awingu, only group policies applied in Remote Desktop sessions are useful.

When logged on to an RDS host, please perform these two procedures.
Adjust the paths to a location for which the user account has "write" permissions.

1. Start an elevated command prompt (Run as administrator)
2. Execute the following command:
gpresult /h C:\logs\gpo_machine.html /f
 

This GPO report contains details on all the group policies applied to the RDS host (computer object).

1. Start a command prompt (when using the affected user's credentials)
2. Execute the following command:
gpresult /h C:\logs\desktop\gpo_user.html /f
