Schema Extensions

Hello,

Apparently the Schema extensions in Active Directory by SCCM (SMS) have been changed.

Executing query (&(ObjectCategory=MSSMSRoamingBoundaryRange)(|(&(MSSMSRangedIPLow<=174742319)(MSSMSRangedIPHigh>=174742319))))
Executing query (&(ObjectCategory=mSSMSSite)(|(mSSMSRoamingBoundaries=10.106.80.0)(mSSMSRoamingBoundaries=RRH)(mSSMSSiteCode=SRV)))
LSGetAssignedSiteFromAD 

How could I do:

- List of extensions used by SMS

- Last Modified Date

Thanks,
Dom
