Restoring an AD LDS instance

Active Directory Lightweight Directory Services (AD LDS) data and log files must be backed up regularly to ensure the continued availability of data to applications and users in the event of a system failure. When you restore a database to an existing AD LDS instance, you must stop the AD LDS instance before running the restore operation. In addition, we recommend that you move (or delete) the existing database and log files from the AD LDS instance before performing the restore operation.

To restore an AD LDS instance

Stop the AgfaHealthcare service.
Delete the files in the "%ProgramFiles%\Microsoft ADAM\AgfaHealthcare\data" folder.
At a command prompt, type
xcopy /os <location>\adamntds.dit "%ProgramFiles%\Microsoft ADAM\AgfaHealthcare\data\adamntds.dit"
where <location> is the path to the folder where the backup file was created.
For example:
xcopy /os C:\Backup\AgfaHealthcare\adamntds.dit "%ProgramFiles%\Microsoft ADAM\Agfa Healthcare\data\adamntds.dit"
Start the AgfaHealthcare service.
Restart Windows Server.
