Does anyone know of a simple method to patch multiple application exes installed on each workstion all connected to a server upon which I would like to simply copy the new exe to each workstation only when I have made a change to the source on the server when the user logs on...

I want to change the local exe (C:\windows\program files\appl.exe) with a new exe from the server... (o:\shared\sst\install\appl\appl.exe) when the server version exe is newer than the one on the hard drive of the users workstation.

Thanks,
Marc
