I checked my ArcGIS Services today and observed that All of my services were gone. Then, I tried to recovered them. In my first step, I opened the mxd that was used before and wanted to re-publish it as a map service. However, the process failed due to 'Feature service requires a registered database'. In this mxd, the map layer is sourced from a gbd file. What should I do to fix the problem? Thanks.
