I setup Anywhere Access (Remote Web Access) for accessing desktops remotely. Even if the remote user selects "Use all my monitors for the remote session," it still only comes up single monitor. I've even tried editing the .rdp file to force it to dual monitors and it won't work. It's almost like it's being forced to a single monitor through some sort of a group policy, but all of the group policies for "computer config\admin templates\windows components\remote desktop services\remote session environment" are "Not Configured." I've also checked the GPs for Remote Desktop Services under User Config group policies and they are all Unconfigured.
I did not setup Remote Desktop Services, I followed the wizard to config Anywhere access. I'm not sure if it's using different policies. But, it looks like that method still configures Remote Desktop Services. I see Remote Desktop Services, Remote Desktop Gateway and Remote Desktop Web Access listed under the Roles and Features in Server Manager
Server is Windows server 2012 R2 Clients are Win 7 and 8
Update: Even if I access another computer internally (on the local network) using RDP and not going through Remote Web Access, I get the same problem. So, I configured another client in a workgroup, not on the domain, and that computer will only come up with a single monitor. That sort of rules out a domain group policy.
