We have a situation where we have services that are pointing to an old geodatabase and when we go to server where the .mxds reside that created the services the source cannot be found (red exclamation point) OR the .mxd's no longer exist. I'm trying to understand how that's possible? I feel like all of the services should contain nothing and when an app is opened it should only show the basemap. Granted the services are showing old data, but how are they showing anything at all. If someone can help me understand how that is working like that I'd appreciate it. Please note, we are in the process of updating all of our services to fix this issue but it's been like this for a very long time.
