what is Property ID?

I have enabled auditing of the IIS Metabase. Now when a change is made, an
event similar to the following appears in the Security event log:

Event Type: Success Audit
Event Source: IIS-METABASE
Event Category: Object Access
Event ID: 4505
Date: 2008/04/14
Time: 4:06:18 PM
User: DOMAIN\jeremiah
Computer: SALESWEBMACHINE
Description:
Metabase Set Data.

Primary User Name: jeremiah
Primary User Domain: DOMAIN
Primary Logon ID: (0x0,0x3D8A88A2)
Path: /LM
Property ID: 6269
Property Name: -
Old Value: -
New Value: 4660
Caller PID: 3444
Caller Image Path: \Device\HarddiskVolume1\WINDOWS\system32\mmc.exe
Result: 0x0

How do I interpret what was changed? I cannot find documentation on
"Property ID" and "Property Name" is blank.
