Enable multiple Remote Desktop connections

You can easily change the default configuration for Remote Desktop on Server 2008 R2.  I believe the same procedure will work on Windows 7 but have not tested it.

Open the Group Policy Editor (gpedit.msc)

Navigate to Administrative Templates \ Windows Components \ Remote Desktop Services \ Remote Desktop Session Host \ Connections

We are interested in two setting here: Limit number of connections and Restrict Remote Desktop Services users to a single Remote Desktop Services session.

Edit the Limit number of connections setting to allow unlimited connections by setting the value to 999999.

Disable the Restrict Remote Desktop Services users to a single Remote Desktop Services session setting.

Be sure to apply you changes.

That is it.
