Troubleshooting Remote Assistance
Remote assistance can be problematic for numerous reasons. The following will break down the most common problems in to categories and will provide a starting place when looking for solutions. Users should be educated on these issues.
No connectivity: If a connection cannot be made between the Novice and Helper, there are several components to look at.
Firewall If there is a firewall, the Remote Assistance connection may not be possible due to the current security policy. Check with your friendly Network Administrator to see if it is within the security policy to allow a Remote Assistance connection.
Network Down As with all networks, it is possible that yours is down. You can test this by trying to make a connection via the Windows Messaging service.
Slow connectivity: If the connection between the Novice and Helper is lagging, there is not much that can be done. Fundamentally, it will be due to inadequate bandwidth. Whether as result of an overloaded network or a low bandwidth connection, there is not much that can be done other than to demote the audio settings if they are enabled. This setting is adjusted using the Settings button on the Remote Assistance window on either the Novice or Helper side. In addition, you can ensure that all other Internet based programs are closed or disabled.

Remote Control Fails If you cannot establish a Remote Control session but you know that you are connected, you will need to ensure that the Remote Desktop settings are correct by right clicking on My Computer > Properties > Remote > Remote Desktop frame and ensure that the Allow users to connect remotely to this computer option is checked.
