The Automatic Reconnection feature will automatically reconnect to the same session, without re-typing logon credentials, if the session is disconnected because of network problems. A maximum of 20 reconnection attempts are made at 5 second intervals.
When a client loses network connectivity, Automatic Reconnection informs you that it is trying to reconnect to the broken session. The session appears in grayscale, and you receive:
The connection has been lost. Attempting to reconnect you to your session.
Automatic Reconnection will count down the remaining reconnection attempts, starting at a default of 20 times.
When the connection is re-established, the Reconnecting window disappears. If the connection cannot be re-established, the session closes.
The Automatic Reconnection feature is turned on by default in Windows XP Service Pack 1 (SP1). You can use Group Policy or the Remote Desktop Connection tool to manage this feature in .NET Server, but you must edit the registry to manage it in Windows XP.
When you loose connectivity in Windows XP:
Your session appears in a grayscale.
A small blinking square icon with a computer network connection marked with a red X appears.
You don't see the countdown.
