How do I resolve a Map Service that is not drawing in ArcMap?

 
If an MD iMAP hosted map service is not drawing in ArcMap, it is likely a cached map service that has been updated recently and ArcMap has created its own local cache of the data.

To resolve this issue:
  1. Remove the service you are having issued with from your ArcMap MXD.
  2. In ArcMap, from the menu bar, click on Customize and then ArcMap options, under the Display Cache tab, click Clear Cache.
  3. From your Catalog window, right click on your connection to MD iMAP Services and click Disconnect and then click Refresh.
  4. Double click to reconnect and then add the service back into your ArcMap MXD.
