Description of the Forefront Client Security Offline Asset Removal Tool
Article ID: 2272146 - View products that this article applies to.
Computers in a production environment are commonly rebuilt or go offline. This may result in orphaned records in the Forefront Client Security (FCS) database. Client Security TechNet documentation
(http://technet.microsoft.com/en-us/library/bb432633.aspx)describes steps for permanently removing computers and discovery rules from the database, but these steps cannot be done in bulk for a large number of computers. Removing a large numbers of computers incurs administrative overhead.
The Forefront Client Security Offline Asset Removal Tool utility described and available through this article is designed to automate the bulk remove of computers and discovery rules from the Client Security database.

Client computers go offline for many reasons, including decommission, re-tasking, and re-imaging. After a day, these computers are shown in the "Not Reporting" section of the Client Security console. After 30 days, these computers are removed from the statistics in the Client Security console, but will still be visible in the Connectivity report as well as in the Operations Manager Administrators console.
The Forefront Client Security Offline Asset Removal Tool is a supported command line utility used to remove both MOM computer objects and the discovery rules for those computers. The utility must be run on the FCS Collection server (MOM 2005 Server) because it uses the MOM data access service (DAS) configuration to locate the OnePoint database. It has the following usage:
/RemoveOlderThanDate <date>: parses the date provided and removes all computers with a last contact date prior to that value
/RemoveOlderThanDays <#of days>: removes all computers with a last contact date prior that number of days previous to today
/RemoveOrphanDiscoveryRules [/RunDiscovery]: removes discovery rules without an associated computer object. The RunDiscovery switch is optional, if you would like to initiate computer discovery after removal
/InputFile <filepath>: locates the file passed and uses it for input. The file can be of the format exported from the MOM Admin console or a list of computers on each line
/LogFile <filepath>: full file path where logging information should be stored. If the switch is not present, logging information will be written to the local directory. If the specified file exists it will be appended to, if it does not exist it will be created.
/DoRemove : actually deletes the MOM computers or rules from the database, without this switch the computers to be removed are simply listed
The /DoRemove switch enables a report-only mode so that you can see what the application will delete without it actually doing so. If removal is performed, offline computers removed will continue to appear in historical reporting for the duration of the reporting retention interval.
The /InputFile switch consumes the export from the MOM Administrators console or a file containing computer names on each line, or a computer and then domain name separated by a tab or space.
The /RemoveOlderThanDays switch was designed to be easily used in a scheduled task created by an administrator to regularly remove offline systems. For this reason, most of the output of the utility is written to the output log file and not to the console.
When computers are removed from the FCS database but their associated discovery rules are not, Client Security administrators see the offline computers return with a 'Pending Install' action in the MOM Administrators console. Using the /RemoveOrphanDiscoveryRules deletes the discovery rules associated with these removed computers and eliminates the 'Pending Install' status during the next time computer discovery runs. There is an optional /RunDiscovery switch which is used to trigger computer discovery immediately after these rules are removed, and eliminates the 'Pending Install' status more quickly. The /RemoveOrphanDiscoveryRules switch also operates in a report-only mode unless the /DoRemove switch is also used.
The utility is designed for use with the Microsoft Operations Manager 2005 database used with Forefront Client Security. The utility will not operate when used in an environment without FCS, including an Operations Manager 2005 installation used for computer health monitoring. The utility must be executed as a user who has permission to invoke the MOM DAS libraries, typically a member of the MOM Admins or Administrators group.
