Maybe you were talking about if the user account I am using was a STANDARD account? That would make sense, but I thought I clearly stated that I was using a Domain Admin account (if not, then I'm still confused)...If this is the case, it means that your (standard) user token has Administrator rights over all of the computers in your network. You might as well disable UAC in this case - it's protecting your own computer, but not any of the other computers that you control...
My understanding is that when RemoteControl tries to connect to another computer, it uses the currently logged on credentials.
As I said, my current username is a Domain Admin.
But regardless of if I am using a Domain Admin account or not, I still want UAC active, so that if I'm browsing and some drive-by nasty tries to install itself, I'll get the prompt (and know to disallow it).
I love UAC, and when used correctly can give me the best of both worlds (protection as if I was a standard user, but convenience because all I need to to id click 'OK' when I am indeed installing something intentionally.
