SUMMARY
Included in Systems Management Server (SMS) 2.0 Service Pack 2 (SP2) is a change to the way in which SMS_NT_Logon_Server_Manager (LSM) handles inactive sites. LSM is the SMS_Executive thread that is responsible for creating and updating SMS logon points. LSM in SP2, by default, does not remove any other site's files (Smslogon\Sites\
xxx) from the primary domain controller (PDC). In earlier versions, LSM removes other site's files from the PDC if there are network issues that prevent other sites from updating the PDC; if a site does not update the PDC logon point, the site is marked as "dead." A new registry value in SP2 is set by default to prevent sites from being automatically removed from logon points. The new value is located in the registry at the following location:
HKEY_LOCAL_MACHINE\Software\Microsoft\Sms\Components\Sms_nt_logon_server_manager\Always Active
The Always Active value is set to 1 (enabled) by default. If you want LSM to automatically uninstall sites that have not updated the PDC, set the value to 0. Microsoft does not recommend enabling automatic uninstallation if you have many sites that share logon points.
By default in SP2, if a site is taken off of the network without Windows Networking Logon Client Installation and Discovery being disabled first, an orphaned folder for that site remains on the logon points. Clients may attempt to install to nonexistent sites if their files are left on logon points. To delete such a site from all domain controllers, delete the site's logon configuration fie (LCF) file from the Smslogon share on the PDC.
