You can add RDS servers to the list of computers in Remote Web Workplace, making them available to anyone with access to RWW. The process is simple, requires no reboot and is immediately active.

1. Fire up regedit.
2. Navigate to HKEY_LOCAL_MACHINE\Microsoft\SmallBusinessServer.
3. Add a new key called RemoteUserPortal.
4. Under the new key, create a MultiString value called TsServerNames. Edit the value and insert the name (FQDN or NBN) of your RDS server. If you have more than one, add them on separate lines.

Note that this will only work if your RDS server is inside the SBSServers OU or a sub-OU (i.e. you're allowed to create other OU's inside the SBSServers OU).
