remote desktop services RemoteApp error on some users after licensing Remote Desktop Services

Prior to purchasing licenses for Remote Desktop Services (server 2008 R2) we tested an application using the "create windows installer" function in Remote Desktop Services .  All worked fine.  Now that we have purchased and installed Remote Desktop Services licenses, the app fails to open for some users.  The trouble follows the user, not the workstation.

The one and only server acts as both Domain Controller and Remote Desktop Services.



When opening the RemoteApp, the server records the following error for the failing users:

Level:         Warning
Keywords:      Classic
User:          N/A

Description:
The Remote Desktop license server cannot update the license attributes for user "username" in the Active Directory Domain "xxxxxx.local". Ensure that the computer account for the license server is a member of Terminal Server License Servers group in Active Directory domain "xxxxxx.local".
If the license server is installed on a domain controller, the Network Service account also needs to be a member of the Terminal Server License Servers group.
If the license server is installed on a domain controller, after you have added the appropriate accounts to the Terminal Server License Servers group, you must restart the Remote Desktop Licensing service to track or report the usage of RDS Per User CALs.

I have verified the membership of the DC is a member of the TS Group and Network Service is also a member, and restarted the services.

What completely baffles me is that it works fine on all workstations for one of the users, and not for the other four users on any workstation.

The users are all members of the same 3 groups - Domain Users, Office Staff, and Remote Desktop Users.
