%11SMS NDS Logon Server Manager failed to read the site control file. Error %1.%12

Possible cause: Low disk space on the drive containing the site control file.
Solution: Make more space available on that drive.

Possible cause: The file is being written to a remote computer that is not accessible.
Solution: Ensure that the remote computer is running and accessible.

Possible cause: Something other than SMS has changed the permissions or attributes of the file or the directory containing it.
Solution: Restore the file's permissions or attributes so that this SMS service can access the file.

Possible cause: The site control file is corrupt.
Solution: Restore the site control file from a backup copy (kept in the \Sms\inboxes\sitectrl.box\history directory on the site server), or run SMS Setup and reset the current installation.

If you ignore this problem, SMS will probably fix it and complete this operation later. If this error occurs repeatedly, refer to your SMS documentation or the Microsoft Knowledge Base for further troubleshooting information.%0
