I faced a problem in Terminal Services Configuration

I faced a problem in Terminal Services Configuration

Dear Ahmad,

However, it is not supported to install the Terminal Services role on the SBS2008 server due to security, performance, and reliability purposes. Even though the installation of the Terminal Services role will not fail, you will receive the error (above u mention) in Terminal Services Configuration when attempting to change the licensing mode from Remote Desktop for Administration to any other mode:

In addition, the SBS Console will crash if you attempt to open any of the following links:

• In the Users tab: "Purchase additional client access licenses"
• In the Computers tab: "Purchase additional client access licenses"
• In the Networking, connectivity tab: "Manage Router" (several locations under properties)
• In the Shared Folders tab: "Browse any of the shares"

If you are experiencing any of these issues, you must remove the Terminal Server service from the SBS 2008 standard server (or Server #1 in SBS 2008 Premium) to regain proper functionality of the SBS console.  You can do so by opening Server Manager, expanding Roles, and selecting the Terminal Services role. On the right hand side pane, select Remove Role Services and uncheck the Terminal Server role, click next and Remove to complete the wizard. 

If you wish to deploy the Terminal Services role in your SBS environment, we recommend purchasing SBS 2008 Premium, which comes with a copy of Windows Server 2008 standard to install on a second machine. It is fully supported to install the Terminal Services role on this second machine.

Hope this Helps you!
