Is there a MS equivalent of VMWare View?

Hi,

I want to virtualize desktops in my company -- small business. If possible, I'd like to use MS solutions from the server to the client. Is there a MS equivalent of VMWare View?

I like VMWare View's ability to allow user to continue working even if network connection is not available e.g. during a business trip, an employee can continue working during a flight from NY to LA.

Thanks, Sam
