Bug: The projection elements FILTERCOORDSYS and FEATURECOORDSYS are not available through the Author interface
** This issue is addressed in ArcIMS 9.0 Service Pack 2 (SP2) **
A. If FEATURE/FILTERCOORDSYS are missing from the PROPERTIES section of a map configuration file, SERVICEINFO does not return projection information.
B. If a custom projection string was used in the map configuration file, there isn't a valid EPSG value.
If unable to download ArcIMS 9.0 Service Pack 2, refer to the article listed in Related Information, below, for a workaround.
