About the Unique Identifier Value for a Resource
Applies To: System Center Configuration Manager 2007, System Center Configuration Manager 2007 R2, System Center Configuration Manager 2007 R3, System Center Configuration Manager 2007 SP1, System Center Configuration Manager 2007 SP2
In Configuration Manager 2007, the Configuration Manager unique identifier property for a new resource class is optional. If you report inventory data for the resource, you must include this property. The Configuration Manager unique identifier value must be unique — it relates your resource discovery data to your inventory data (SMS_G_xxx). Typically, hardware resources use a GUID to uniquely identify individual resources.
The format of the Configuration Manager unique identifier value is as follows.
<ID Type>:<ID Value>
For example, Configuration Manager uses a GUID to identify Configuration Manager clients.
GUID:4976DCD4-CAAE-11D2-8E00-00104BCC3648
You can use any <ID Type> and <ID Value> values to identify a new resource. However, when discovering data for an existing resource type, you should follow the convention that is used by that resource type.
