Check if a remote desktop connection is active in Windows 7

Question

As part of a business solution we are offering several remote desktops to a user base. Currently the users must go system by system attempting to connect and find one that is not already being used. I'd like to see if there is a command that can be run to quickly query an IP and see if there is an active remote connection already.

I've run across a 'wmic' solution already, but this only seems to work if the person running the command has admin access on the destination machine. I don't need a username returned or any information other than if there is a currently in-use remote connection.

Any idea's?

Researched solutions that didn't pan out listed below:

wmic /node:IP ComputerSystem GET UserName ---Returns only if requestor is an admin

qwinsta /server:IP ---RPC is not enabled on all machienes

eventvwr IP ---Too technical and time consuming for end users

Thanks in advance

Solution

query session /SERVER:servername
