Objective
This article explains how to configure Automatic Client Re-connection.
Access Citrix Workspace. The first time you open Citrix Workspace, input 'citrix.engr.illinois.edu' without quotes in the server address field and click 'Add.' If you encounter an error, disconnect from the Cisco VPN, select the '3TunnelAll' profile, and reconnect to the VPN. Select 'Finish' on the success screen.
Instructions
Users can be disconnected from their sessions because of unreliable networks, highly variable network latency, or range limitations of wireless devices. With the Auto Client Reconnect feature, Receiver can detect unintended disconnections of ICA sessions and reconnect users to the affected sessions automatically. When this feature is enabled on the server, users do not have to reconnect manually to continue working. Receiver attempts to reconnect to the session until there is a successful reconnection or the user cancels the reconnection attempts.
Configure Auto Client Reconnect using the following policy settings:- Auto client reconnect. Enables or disables automatic reconnection by Receiver after a connection has been interrupted.
- Auto client reconnect authentication. Enables or disables the requirement for user authentication upon automatic reconnection
- Auto client reconnect logging. Enables or disables logging of reconnection events in the event log. Logging is disabled by default. When enabled, the server's System log captures information about successful and failed automatic reconnection events. Each server stores information about reconnection events in its own System log; the server farm does not provide a combined log of reconnection events for all servers.
Auto Client Reconnect incorporates an authentication mechanism based on encrypted user credentials. When a user initially logs on to a site, the server encrypts and stores the user credentials in memory, and creates and sends a cookie containing the encryption key to Receiver. Receiver submits the key to the server for reconnection. The server decrypts the credentials and submits them to Windows logon for authentication. When cookies expire, users must reauthenticate to reconnect to sessions.
Cookies are not used if you enable the Auto client reconnection authentication setting. Instead, users are presented with a dialog box to users requesting credentials when Receiver attempts to reconnect automatically.
Note: For maximum protection of users’ credentials and sessions, use SSL encryption for all communication between clients and the server farm.Disable Auto Client Reconnect on Citrix Receiver for Windows by using the icaclient.adm file. For more information, see the Receiver for Windows documentation, in eDocs.
Settings for connections also affect Auto Client Reconnect.

Configure connections for Automatic Client Reconnection
By default, Auto Client Reconnect is enabled through policy settings at site level. User reauthentication is not required. However, if a server’s ICA TCP connection is configured to reset sessions with a broken communication link, automatic reconnection does not occur. Auto Client Reconnect works only if the server disconnects sessions when there is a broken or timed out connection.
In this context, the ICA TCP connection refers to a server's virtual port (rather than an actual network connection) that is used for sessions on TCP/IP networks.
By default, the ICA TCP connection on a server is set to disconnect sessions with broken or timed out connections. Disconnected sessions remain intact in system memory and are available for reconnection by Receiver.
The connection can be configured to reset, or log off, sessions with broken or timed out connections. When a session is reset, attempting to reconnect initiates a new session; rather than restoring a user to the same place in the application in use, the application is restarted.
If the server is configured to reset sessions, Auto Client Reconnect creates a new session. This process requires users to enter their credentials to log on to the server.
Automatic reconnection can fail if Receiver or the plug-in submits incorrect authentication information, which might occur during an attack or the server determines that too much time has elapsed since it detected the broken connection.

Let's say that you have a session running and it gets dropped for whatever reason. If you have auto client reconnect set, when the farm is trying to reconnect:- the farm has the session marked as disconnected, and
- the user sees that the session has disconnected, and an attempt is being made to reconnect.
If Session Reliability is in play:
- the farm has the session marked as Active and
- the screen freezes on the last frame during the attempted reconnect process, without any indication to the user.
