Are you talking about running RAdmin and VNC (for example) on the same computer at the same time? If so, that's totally doable.

I have several clients' computers that have multiple remote access programs on them. As long as they're listening on different ports, they will all get along nicely. I've even run 2 different versions of RAdmin server on the same machine - v2.2 listening on port 4900, and v3.x listening on 4899!

Hope this helps!

Good point, Eugene. I had forgotten to account for the Mirror Driver; I can see where that could cause issues.

In fact, I encountered a Mirror Driver conflict not that long ago; I believe it was with the RDP based remote control built into Microsoft's beta Live Mesh software. I didn't care much for that aspect of Live Mesh (it was VERY slow), so I disabled it and all was well.
