Is there a way to tell which feature class in a db was used to publish a service? I'm trying to clean up an existing database and there are feature classes with similar or duplicate names (ie cityaddress vs cityaddresses_1 vs city_address), I don't want to delete any of them until I can be sure they don't play a role in a running service. Any ideas?
If you have access to the ArcGIS Server machine, in the ArcGIS Server folder you should find a system folder and within that folder there should be an input folder. Within that folder inside the service folder of the service you are after, a copy of the MXD you use to publish the service can be found. Open that MXD to examine the sources that are used for the service.
Natalie,
Apart from the steps shared by Xander, there are few more methods where you can find the names of the feature class that were used for the map service.
