Windows 7 Using "Offer Remote Assistance" from Windows 2003 server to Windows 7

We are rolling out Windows 7 and need a way to remotely take over machines. We have a Citrix farm running on a Windows 2003 server environment and would like to publish an "Offer Remote Assistance" icon for our techs. Can we use 2003's Offer Remote Assistance to connect to Windows 7 machines? I've been looking but haven't found a definitive answer. Thanks...
