IT people, I need your help! ***WARNING: Tech jargon!***

Computer A = your own desktop running Win7
Computer B = a server running Windows server 2003 or newer

OK, this is something that I cannot wrap my head around. What happens if you RDP into computer B from computer A, then from within computer B, you VNC BACK into computer A?

Does this create an infinite loop?
What desktop do you see?
Would this cause some kind of feedback loop?
Would this create a space-time singularity? or a super villain maybe?

WHAT WOULD HAPPEN?! I asked the network manager, and all he said was "I don't know, but don't do it on my network."

I may have to try this on my test network at home tonight...

Am I the only one here who is seriously perplexed by this? I HAVE to try this tonight, or I won't be able to sleep. Maybe I'll record the whole thing on video... I'll have to use a third computer running wireshark, and monitoring the switch's load to really see what happens.

Not sure if using VNC will cause the same effect, but I recall seeing this way back. Had to google to find the link, but here's something from 2009. (May not apply to Win7)

Remote Desktop Feedback Loop - Jon’s Diary

Hmmm. looking closer that's an Apple OS. Well the one I recall seeing was Windows and looked pretty much the same.

I didn't think you could RDP into a machine that already had an active RDP session, or if you did, it would just create a new session with a new desktop. Same thing with VNC. But... That does look really cool and if those are the results, I'd love to have a screenshot and use it as a wallpaper.

True but in this case you'd have RDP going in one direction and VNC going the other way so I'd think that it would work.

Yea, it wasn't terribly exciting... It created the infinite window within a window effect. I didn't see any jump in network traffic or even spike in CPU or RAM load... No micro worm hole, no super villain, and my switch didn't blow up. Dang...

It's interesting. Is it a perfect loop? Most feedback loops you'll have interference due to analog signal loss, what about here? Will this loop go forever without decay?
