Citrix MetaFrame Checking

Overview
The program Logonchk.exe is the logon authorization program. There are two recommended ways to invoke this program, automatically on NT, 2000 and XP based machines as setup by SBSetup.exe and manually, usually as part of a logon script. Even though you would typically launch and run Logonchk.exe only at logon via the NT logon script or other startup script, you can run it at any time. For example, you could run it in a batch file whenever you need to check logons before allowing the user to proceed. Specify the NT logon script in the users’ profile if you want only certain users to be authorized. Logonchk.exe will run on all 32-bit Windows.
 

NOTE: Users are authorized in the following order:
 

Citrix MetaFrame / WinFrame Authorization
The MetaFrame/WinFrame authorization feature set provides the ability to use ServerBoss tools on Citrix MetaFrame and Citrix WinFrame Servers. This feature set uses the Citrix API in addition to NT APIs to provide the best level of ServerBoss performance and stability on Citrix server platforms.  No client-side configuration or software installation is required for Citrix authorization.
 

NFuse and Program Neighborhood
Logging into NFuse or Program Neighborhood does not create a persistent session. There is no way for ServerBoss to determine when these API type logons are executed and Winlogon is not invoked on a server. Therefore, you cannot directly restrict by NFuse or Program Neighborhood logons. You can provide the same effect using logon checking and/or application checking as long as you understand how NFuse and Program Neighborhood work in terms of creating new sessions.
 

When you use Program Neighborhood or NFuse to connect to your application set you will have one session for every server you connect to. For example, say you have two Citrix servers, Citrix1 and Citrix2. Citrix1 is publishing C1Outlook and C1Project. Citrix2 is publishing C2Word and C2Excel. When you open Program Neighborhood or NFuse, you will not have any sessions. If you then run C1Outlook, you will have one session on Citrix1. If you then run C1Project, you will still have only one session and will be running both apps in the same session. If you then run C2Word, you will have a session on Citrix2 as well. If you run C2Excel, you will have one session on Citrix1 and one on Citrix2. Even though you have all four published applications running at the same time you will only have two sessions, one on Citrix1 and one on Citrix2.

The exception to this rule is publishing a desktop. Connecting to a published desktop will always create a new session that can’t be shared by another other published apps.
 

Integrating with ServerBoss
If you want to authorize your users for a certain number of launches of any given application you should use application checking and publish the renamed SBAppChk.exe (see application checking installation). Using the information above you may also be able to use logon checking to fit your needs. If you have any questions or would like help configuring ServerBoss to work in your scenario please contact ServerBoss support by calling (800) 878-0790 or emailing support@serverboss.com.

NOTE: Either MetaFrame/WinFrame or Terminal Server authorization feature set is required in order to purchase and use the application authorization feature set. 

NOTE: LAN checking is not required for Citrix or Terminal Server authorization, even when the remote clients are on the same LAN. No client configuration or software installation is required for Citrix or Terminal Server authorization.
