There are several requirements that are needed by both the Helper and the Novice in order for Remote Assistance to work. These requirements include the following:
· The Helper and the Novice computers must both be running Windows XP
· In order to receive an acceptance notice of the invitation, the Helper must be connected to the Internet
· Depending on the Invitation delivery method, the Novice will need either Windows Messenger, a MAPI Email program, or a means of delivery for a file
· If the Helper or Novice is behind a firewall, the firewall will need to be configured to allow Remote Assistance traffic via outbound TCP port 3398
· Proper configuration of Remote Desktop properties must be set if remote control is required
· A strong password is needed by the Helper to establish the initial connection to the Novice
Although the requirements are few, a connection can be difficult to create if either the Helper or Novice is part of a corporate network. End-users behind a corporate firewall may require help in setting up remote assistance. This is due to the level of security needed to ensure data integrity in the enterprise. If Remote Assistance is necessary and your users cannot establish a connection due to current firewall settings, you will need to make sure that the firewall allows port (3398 Outbound TCP) from the client in order to successfully establish a connection.
