• Java
• Nfuse
• 32-bit Microsoft windows-based operating system such as
  • windows 9x
  • windows NT 3.51 or 4.0 (Workstation,Server)
  • windows 2000 (pro,server,adv.server,Data center)
  • citrix Metaframe 1.0 or 1.8
  • citrix Metafrmae XP
  • citrix Winframe 1.7 and 1.8

Client devices can use PN to :

• connect to remote applications without first configuring settings for the connection and application;
• access all the applications that are configured for their use by authenticating themselves on the network;
• access remote applications from the Start menu or the desktop of the ICA client device;

Application types

All ICA clients can connect to two types of applications :

1. Published
2. Server

1. start a specific application or server's desktop.
The administrator ,with CMC ,pre-configure applicatios and server desktops into published applications.
Can run on a single server or balanced to run on a multiple servers.
If the published application is load balanced ,the data collector determines which server should run the application ,based on the load balancing parameters specified for the XP servers.
Users of ICA win32 ,Java and Nfuse clients ,who have been given access to the application ,will see the application in their PN ,while users of other IcA clients need to add the published application to their Remote Applications Manager before they can use the application or use the ICA passthrough.

• published videos can only be run by ICA win32 clients that have windows media player installed;
• videos cannot be published on Metaframe XP;

2. start an application ,video or server desktop on a particular server.
This differ from a published application ,which is configured on a server does not require application-specific information from the user.

Types of users

Published applications can be run from two types of users listed below :

• anonymous user accounts : created automatically when XP is set up on the server ;by default 15 anonymous user accounts are created with Guest access ;don't need to enter a username or password.
  N.B.:anonymous user accounts cannot be created on domain controllers.
• explicit users accounts : created using Active Directory Users and Computers or User Manager for Domains ;allow administrators to control who can and cannot access and use a published application ;explicit users account must enter a username and password.

CITRIX PROGRAM NEIGHBORHOOD

PN is located on the desktop of the ICA win32 client device and can also be accessed from the Start/Programs/Citrix ICA Client menu.

• Custom ICA connections are configured by a user at an ICA client device.
  The user must select the server or published application to be started and then identify the executable for the custom ICA connection.
• Published applications are configured by an administrator to start a specific application or a server's desktop.
  Published applications can run on a single server or can be load balanced to run on multiple servers.
  

CITRIX PROGRAM NEIGHBORHOOD INTERFACE

Allow users to run appl. located on XP servers.

USING CITRIX PROGRAM NEIGHBORHOOD

If a user has rights to use a particualr application ,it will appear in the Citrix PN.

Defining a Default Set of Applications

PN contains the appl. sets that administrators define and the custom ICA connections the users define.
To use an application ,users open the folders containing the application and double click the appl. icon to start.
Its possbile to set an application set as default to reduce the number of steps to access a published applications ,a little mark is added to the icon of the application set ,so the next the PN is opened ,the icons within the default folder are displayed.

Starting an application

When users double click a program icon ,one of two things happen :

• The application will start if :
  • the application was configured for explicit user access and another application in the application set is already running.
    The PN caches the username and password.
    Only if permissions differ between applications in the application set will user hav elogn on again during the session ;
  • the Save Password option was checked during a previous logon.
    The save password option writes the password to the local disk.
    The PN retrieves the password when needed.
  • the application was configured for anonymous user access;
  • Use Local Username and Password (Pass-Through authentication) was selected for the application;

• The user will be asked to supply logon credentials if :
  • this is the first application in the application set to be started and the Save Password option was not checked during a previous logon ;
  • a custom ICA connection is being started.
    Each custom ICa connection requires a separate logon.
    Future logons can be avoided for a specific custom ICA connection by selcting the Sava Password option.
  • an encryption setting other than Basic is used by the application set or custom ICA connection.

Closing, Disconnecting and Reconnecting to an Application

Whe the user is done using an application in an application set, the application can be closed without affecting other running applications.
The connection to the XP server will exist until all applications in the application set are closed.
To close an application do one of the following :

• click EXIT in the system menu ;
• click EXIT or CLOSE in the first menu of the application ;
• click the X in the upper right corner of the windows ;
• click ALT+F4.

Not every application supports all of the above methods for closing an application.
If a user or a connection is configured to run in a disconnected state, a user can disconnect from an application, rather than close it.
In a disconnected state, the application continues to run and process information in a session on the XP server, but the application is not displayed on the user's device.
This happen until the timeout is reached ,or the user reconnect to the disconnected session.
To disconnect from an application, a user can do one of the following :

• press SHIFT+F3 ;
• double click the ICA Connection Center in the lower right corner of the windows taskbar.
  Select the server on which the application is running and click DISCONNECT.
  • using the Citrix Connection Configuration utility to configure a connection to run in a disconnected state (ON A BROKEN OR TIMED OUT CONNECTION).
    Use Active Directory ... or User Manager ... to configure users to run connections in a disconnected state.
  • applications running in a disconnected state continue to run and process information on the server even though the user is no longer accessing the application in the ICA session.

To reconnect to a disconnected session, do one of the following :

• double click the program icon in the Citrix Program Neighborhood.
• double click the ICA Connection Center in the lower right corner of the windows taskbar.
  Click the server on which the application is running and click Reconnect.

Configuring Global Settings

Custom ICA Connection and the application set folder have global settings that affect the custom ICA connection and the applications within them.
To customize this settings : right clicking the 'Custom ICA Connections' folder and clicking 'Custom Connections Settings' and right clicking an application set folder and clicking 'Application Set Settings'.
This is possible using File menu items or Settings icon in the toolbar too.
The settings for a custom ICA connection override the global settings.
The settings for individual applications within an application set cannot be changed, but can only be altered as a group by changing the application set settings.

The global settings for the Custom ICA Connections folder have two tabs : 'Connection' and 'Default Options'.
The global settings for an application set have three tabs : 'Connection', 'Default Options' and 'Login Information'.

THE GLOBAL SETTINGS FOR CUSTOM ICA CONNECTIONS

THE GLOBAL SETTINGS FOR APPLICATION SET

CONNECTION TAB

• Always Use Network Protocol : specifies that the network protocol selected in the Server Location field of the application set should be used.

N.B.: application set settings only

Network Protocol : identifies the network protocol that the custom ICA connections and applications within the application set should use.

If multiple protocols are installed and an application is published with multiple protocols, the protocol to be used will be selected in the following order :

• TCP/IP : auto-locates a server in the server farm if UDP broadcasts are enabled.
  Requires that a server's address be specified in the address list if UDP broadcasts are not enabled or ICA clients are in a different subnet than the data collector.
• TCP/IP+HTTP : auto-locates a server in the server farm using the XML service.
  Requires a server's address be specified in the address list if the server farm is set to mixed mode.
• IPX
• SPX

FINDING NEW APPLICATIONS SETS

When an administrator publishes an application this is added to an application set.
If a user has access to the new published application within an application set, that application will appear automatically in the user's citrix PN.

Find New Application Set allows a users to locate and add applications sets from other server farm to their Citrix PN and uses the following info to find and configure the application set :

Specifies how the XP server will be accessed :

• Local area network
• Wide area network
• Dial-up networking (PPP/RAS) connect using a modem through a remote access server.
  ICA Dial-in is not available for application sets, it can only be used to connect to custom ica connection.

Users can change the settings for the Custom ICA Connection in the PN by clicking the custom ICA connection's program icon and the Properties icon.

CUSTOMIZING APPLICATION SETS AND CUSTOM ICA CONNECTIONS

This feature allows users to have the applications that they use set up specifically to their liking.

Placing Application Icons on the Desktop : If a particular application set or ica connection is used frequently,a user might want to add the icon to the local desktop.
There are two methods of adding an application icon to the desktop :

1. desktop shortcuts
2. desktop integration

1. are created by :

• dragging an icon from the PN to the desktop;
• right clicking the icon and using Create Desktop Shortcut;
• clicking the icon of the application to be placed on the desktop and clicking the File --> Create Desktop Shortcut;

N.B: desktop's shortcut are not deleted automatically must be deleted manually.

2. are created automatically for an application in an application set if Add Shortcut to the Client's Desktop was selected when the application was published.
If Add to the client's Start Menu was selected the application name will appear in the client's start menù.

Users at client devices can disable desktop integration (desktop and start menù) by changing the settings of an application set to Turn off Desktop Integration for this Application Set.
After this feature is disabled the icons are deleted automatically.

N.B.: Desktop shortcuts can be distinguished from a desktop integration icon by opening the properties of the icon, on the shortcut tab there is /DI parameter.
N.B.: Custom ICA connections cas use desktop shortcuts, but not desktop integration icons.

Deleting Custom ICA Connections : deleting an icon does not the application from the XP server.
To delete a custom ica connection, use the File --> Delete menu items, use the Delete icon in the PN toolbar or by right clicking on the icon and select Delete.

N.B.: deleting a desktop shortcut does not remove the program icon from the Custom ICA connections folder or an application set folder.

Renaming Application Sets and Custom ICA Connections : application sets receive their name from the name of the server farm on which they were created.
To change the name of a custom ICA connection or application set, use the File --> Rename menu items or right click the item and click Rename.

N.B.: users cannot rename the Custom ICA Connections folder or individual applications within an application set.
N.B.: users can rename an application set.
However, when they refresh or restart the PN, two copies of the application set will appear.

Duplicating Application Sets and Custom ICA Connections : users may want to customize an application set or custom ICA connection without affecting the properties and settings of the original can duplicate them.
To duplicate use the File --> Duplicate item menu or right click and click Duplicate.

N.B.: users cannot duplicate the Custom ICA connection folder or individual applications within an application set.

Copying a Published Application to Custom ICA Connections : to copy a published application from an application set to the custom ica connections folder use the File --> Copy to custom connections menu items or right click and click Copy to Custom Connections.

Changing Properties of Individual Custom ICA Connections : users cannot change the properties of individual applications in an application set.
