Okay, so I'm trying to use Microsoft's new-ish Remote Desktop app from the Mac App Store to control my work Mac Pro from my Macbook Pro. We use a domain controlled server and in order to use this from home, I'll obviously need to VPN into the network to gain access. Which I have done already. Now the Apple Remote Desktop app works fine, but other users do not want to spend the $80 for the Apple alternative when the Microsoft one is free. Please advise on how to set this up using the Microsoft option. Thanks!
