Description
The server-side publishing tool failed to determine the service's input folder name. This can happen if the folder was renamed or deleted after being registered with the server.
The input folder is used when you publish services and service definitions. For each service that you publish, a folder containing the GIS resource is created in the input directory. If you selected to include the data referenced by your service when publishing, the data appears within the same folder as its parent document. This input folder is necessary for the service to run properly on the ArcGIS Server site.
This server system tool is invoked by the publishing client (for example, ArcGIS Desktop) when you create a service.
Solution
Verify that the server's input folder exists and is properly registered with the server.
