Remote Assistance en firewalling
Remote assistance relies on full network connectivity between the expert user's computer and the novice user's computer over the following network ports:
- TCP port 135
- TCP port 3389
- All TCP ports that are greater than 1024
If port filtering exists for any of these ports between the two computers, Remote Assistance will not work.

Zie ook DCOM voor het vast instellen van de gebruikte poort boven de 1024.
