Bobtran,
Gotcha. Sorry, I was not aware of that limitation. Well, Microsoft is in the business of generating a profit. Just because you use Windows Home Server does not automatically turn on the RDP functionality that they ripped out of Home based versions of the client Windows operating systems.
I think it's sad that RDP is not just enabled on all versions of Windows. Seems very useful for helping to remotely troubleshoot systems and home users likely need that more than anybody else. Clearly the Windows Home Server product is reliant on the RDP functionality, and it's inclusion in the client OS is based on the version of the client computer and is not based on the server software used.
