I keep hearing all these great things about ArcGis 10.x and geocoding. Gotta give it a try some time...
All serious aside, unless things have radically changed in 10.x from 9.3.x and earlier, you should be able to access the locator from ArcCatalog or ArcMap. Take a look at this link for ArcCatalog connections. It's pretty straight forward.
In the good old days of ArcMap 9.3 (which is where I live, work and play) one simply goes to the Tools menu, and selects Geocoding/Address Locator Manager. Then use the add button to navigate to the connection you've already set up in ArcCatalog. See attached image.
Hope this helps.
Well, I just added a published locator service to a 9.3 ArcMap session using the geocoding tool bar and everything works. Don't know why it doesn't work for you.
You have no problem reverse geocoding through ArcMap but you get an error when you add the locator to the "Reverse Geocode" tool? Can you try to connect to ArcGIS Online?
The link below has information on how to add the locator to ArcMap.
That's correct. I was able to use the locator at the link you provided in ArcMap and with the Reverse Geocode tool with no problems.
So, I tried the same procedure in the Reverse Geocode tool with the locator published by our county GIS office and I got "ERROR 000732: Input address locator does not exist or is not supported." But, just like before, I can add this county locator to my Address Locator Manager in ArcMap with no problems, and use it with the Geocode Toolbar to search for addresses.
