I'm having nearly the same problem as above only with the Election Polling Places App. Everything comes up fine (right extent, base map shows, my own polling locations show, etc) but when I enter an address it zooms to the correct address, highlights the precinct, but then just stays there with a swirling icon and "finding precinct" message (even though the right precinct is now highlighted in the map).
One note: In step 3 (defining the Application Pool) ESRI support walked me through this and because I have version 6 of IIS Manager, I needed to right click on the directory and go to "properties" then click on the "create" button, then OK. Nothing was said about the drop down Application Pool menu so it is still on DefaultAppPool instead of either of the other choices (ArcGISApplicationAppPool or ArcGISServicesAppPool). Do you think this could be the problem?
Thanks for any help you can give,
Leitha
