SYMPTOMS
When multiple Systems Management Server (SMS) sites share the same Microsoft Windows NT domain, Windows clients may begin to deinstall the SMS client software after performing Windows Networking Logon Client Installation or Discovery. This problem can be sporadic, with clients appearing to reinstall the SMS client during a future logon.

When you check the primary domain controller's Smslogon share, the Sites\ folder for one or a number of sites that share the logon point may be missing or empty. Additionally, the Sitescfg folder on the logon point is missing the _cfg.lcf files for one or more sites.

These symptoms are more likely to occur on a Windows NT domain in which domain controllers exist across slow links.



CAUSE
During an SMS_NT_LOGON_SERVER_MANAGER polling interval performed by one of the sites sharing the SMS Logon Point, connectivity to the domain's primary domain controller (PDC) was lost for a short period. During the period of communications loss, the SMS site server was unable to read the configuration files in the PDC's Smslogon\Sitecfg folder. This can cause a site server that is not currently the senior site to assume the role of the senior site, and perform a domain deinstallation of all sites for which it is unable to find a _cfg.lcf file.

You can consider the domain deinstallation process performed by Logon Server Manager to be the same as if Windows Networking Logon Installation or Windows Networking Logon had been disabled for some sites in the domain. As part of this process, the Sites\ folder on the SMS Logon Point is removed from the PDC and the Logon Point configuration is replicated to all other domain controllers in the domain. Any clients that run the SMS logon script for any of the deleted sites are unable to find the configuration files for the site on the SMS Logon Point. The SMS client, being unable to determine the site boundary from the site's Netconf.ncf file, begins the deinstallation process.



RESOLUTION
To resolve this problem, obtain the latest service pack for Systems Management Server version 2.0. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
