Hello,

In order to enable Multiple RDP connections on Windows server 2008 , below settings need to be checked.

1. Start > Administrative Tools > Terminal Services > Terminal services configuration. On the properties of RDP-TCP , network adapter, you can set number of allowed connections .

2 .Start > Run , type gpedit.msc . Expand Computer Configuration > Administrative Templates > Windows Components > Terminal Services > Terminal Server > Connections > Disable Restrict Terminal services users to a single remote session. By default, this policy restrict terminal services users to a single remote session which causes the user being log off if the other person log into the server with the same user.
