What are the requirements for Windows Remote Assistance over Teredo?
- by Jens
I try to get the Windows 7 (or Vista) remote assistance feature to work, without using UPnP on the novices computer.
After enabling Teredo on the expert's computer (that is in a corporate network, and therefore has teredo disabled by default), I tried to connect to the novice both using Easy Connect and the invitation file with no success.
My triubleshooting included the following (so far).
A connection to the novice from my home pc was successful, hinting at a misconfiguration on the experts side.
Both computers have a "qualified" connection to the Teredo Server.
Both computers have a valid Teredo IP, access to the Global_ PNRP cloud and can resolve names registered with PNRP on the other computer.
The expert can resolve the PNRP Id automatically generated with an Easy Connect help request
Both computers can ping the other's PNRP name.
Both computers can ping the other's Teredo IP Address using ping -6
Now, I am a little stumped. I expected Remote Assistance to work at this point, since my corporate firewall has no Teredo filtering. What could RA cause not to work in this setting?
Thanks in advance!
