Maybe i'm kicking in a open door but after several hours of searching on the web I didn't find the right solution for configuring RemoteApp on a 2008 R2 RDC Host box.
We have a single server standalone Windows 2008 R2 RDC Hostserver in Workgroup Mode on which we want to use RemoteApp. I followed the (config)Tutorials from MSTerminalServices.org about how to configure Remote Gateway, Terminal Services and RemoteApp. We also installed a multi-domain certificate from Comodo and made the corrections in public DNS. Until this everything works just fine, RDC connections thru Remote Gateway (SSL) and RDWeb works fine but clicking on a published app in RemoteApp the server cannot be found!
All services reside on a single serverbox and further investigation brought us to the RemoteApp Manager where a exclamation mark is at the section "Distribution with Web Access Computers Group is empty". According to Technet documents I should populate the TS Web Access Computers Security Group doing the following:
On the RD Session Host server, click Start, point to Administrative Tools, and then click Computer Management.
In the left pane, expand Local Users and Groups, and then click Groups.
In the right pane, double-click TS Web Access Computers.
In the TS Web Access Computers Properties dialog box, click Add.
In the Select Users, Computers, or Groups dialog box, click Object Types.
In the Object Types dialog box, select the Computers check box, and then click OK.
In the Enter the object names to select box, specify the computer account of the RD Web Access server, and then click OK.
Click OK to close the TS Web Access Computers Properties dialog box.
But there is no Object types "Computers" available! so I can't add anything to this group!
Does anyone have a solution or a walktrough for me to enable RemoteApp on a RDC singleserver in Workgroup Mode?
