Why is GUID present in the response.

[RickeyTom]

I was using the find command against the ArcServer that has the millers ranch published to it.


[ATTACH=CONFIG]34650[/ATTACH]

http://localhost:6080/arcgis/rest/services/MillersRanch/MillersRanch/MapServer/find?searchText=4444&contains=true&searchFields=Objectid&sr=&layers=4&layerDefs=&returnGeometry=false&maxAllowableOffset=&geometryPrecision=&dynamicLayers=&returnZ=false&returnM=false&gdbVersion=&f=html

The results are supposed to display all the attribute related to feature 4444 on layer 4 (attribute related information)

# results : 1

4444
OBJECTID: 4444
SHAPE: Polygon
PID: 2161400000006000
ADD_HOUSE: 00000
ADD_DIR:
ADD_STREET: WARNER PARK RD
ADD_CITY: MANHATTAN
ADD_STATE: KS
ADD_ZIP: 66503
SHAPE_Length: 9710.937489
SHAPE_Area: 3804691.848966
GUID: Null


But I also get this GUID. Where does this come from.
When I execute this same command against another ArcServer, GUID does not appear.
This implies some kind of server setting.
