256986 Description of the Microsoft Windows Registry



SYMPTOMS
When logon points are shared by multiple sites and one domain is removed from logon installation and logon discovery, Logon Server Manager (LSM) tries to remove the site from the logon points. This succeeds, but the domain entry in the site server registry and site control file are not updated and removed. Because of this, Logon Server Manager (from that site) continues to try to connect to the primary domain controller (PDC) of the appropriate domain during each scheduled update interval and repeatedly tries to uninstall.



WORKAROUND
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To work around this problem, delete the domain in the following site server registry key:

HKEY_LOCAL_MACHINE/Software/Microsoft/SMS/Components/SMS NT Logon Server Manager/Domains

After the registry key is removed, the entry is removed from the site control file.



STATUS
Microsoft has confirmed this to be a problem in Systems Management Server version 2.0.



MORE INFORMATION
Excessive network traffic and site server processing are experienced as each site that wants to remove the domain continues to retry during each logon point update cycle. By default, this occurs once per day. Logon Server Manager connects to each domain controller in the target domain during each update cycle whether or not it is the senior site. Networks with hundreds or even thousands of domain controllers, many of which are using slow connections, are the most effected. The only way for this cycle to end normally is when all sites have removed the domain. When this occurs, each site completely removes the domain from its site and never tries to connect to it again. This happens for senior sites as well as junior sites.
