I am using ArcGIS Desktop 10 SP1 and trying to reverse geocode some tornado sirens. The locator that I want to use is through a published service (by a third party) but I can't figure out how to enter this locator into the "input address locator" field in the "Reverse Geocode" tool's dialog. Whenever I try to browse to it through my "GIS Servers" folder or copy and paste in the web address, I get an error stating that the locator doesn't exist or is not supported. I know this not to be the case because I can connect to it and search for addresses just fine outside of this toolbox tool.
I don't do a lot of geocoding, and I have very little experience working with ArcGIS Server services, so I may definitely be doing something wrong, but I really don't know what. Does anyone have any ideas?
Thanks.
