How is Initial Extent set in Map Service

Discussion created by mkoneya on Mar 28, 2013
Once published, a ArcGIS Map Service has a Full Extent and an initial Extent property.    These two values don't match in our map services.    The Full Extent in the map service matches what I have set in the MXD data frame Extent at time of publishing, but I don't understand where the initial extent comes from.   

How is the initial extent property set for a Map Service,  and is it possible to change after publishing?
