I’m not exactly sure why but the first result I got from Google was actually the following forum post:

Server Manager –> Roles –> Remote Desktop Services –> RemoteApp Manager –> RD Session Host Server Settings:

Desktop launches – Allowed
Launching of non-published programs during client connection – Enabled
I was able to log into the server with a regular domain user account once the policy was modified.
**Note that a few users from forum post link I included earlier mentioned that the problem comes back after the server is rebooted but I did not experience this.
