Found this for you,
Keep-Alive Connections - This policy is found under Computer Configuration\Administrative Templates\Windows Components\Terminal Services and is useful in environments where a Terminal Services user's network connection is unreliable, for example when a remote user is connecting to a Terminal server over a WAN link. What happens is that when you enable this policy and specify a keep-alive time interval, the Terminal server periodically checks to make sure the user's session is still connected. Then if the network link is determined by the server to have gone down, the server puts the user's session into a disconnected state so that when the link comes back up the user can reconnect to their session and continue their work. What might happen if you don't enable this policy is that the network link could go down and leave the user's session in an active but orphaned state, and then when the link comes back up the user won't be able to reconnect to their session on the server because it is considered active (in use) and not disconnected. The user may then start a new Terminal Services session, leaving the orphaned session still running on the server and consuming resources that could be used for other users.
