Modifying Configuration.mof file on SCCM 2007 Server

To change the frequency of Client Access License (CAL) collecting data in Asset Inteligence in SCCM 2007, Configuration.mof has to be modified. Configuration.mof file is located on:
C:\Program Files (x86)\Microsoft Configuration Manager\inboxes\clifiles.src\hinv

Example:

// CAL tracking server side configurations and policy
[Singleton]
class CCM_CALTrackConfig
{
uint32 CALCollectionType;
uint32 CALCollectionFrequencyDays;
uint32 CALCollectionFrequencyMinutes;
uint32 CALCollectionTimeWindow;
string CALCollectionSupportedWindowsVersions;

};

instance of CCM_CALTrackConfig
{
CALCollectionType = 3; //0-Disabled, 1-User CAL, 2-Device CAL, 3-All
CALCollectionFrequencyDays = 2;
CALCollectionFrequencyMinutes = 60;
CALCollectionTimeWindow = 90;
CALCollectionSupportedWindowsVersions = "5.0,5.2,6.0";

};
