When attempting to overwrite and restart existing ArcGIS Server services, the following error is returned:
Error: The system cannot find path specified. Probable cause: The file is inaccessible to Server.
This issue occurs if the machine contains two ArcGIS Server directories. The existing services folders are not transferred to the new 'arcgisinput' folder commonly located at:
The services' folders store all MXDs that are used to publish the services. Without the MXDs, the server is unable to overwrite or restart the existing services.
Note: This issue does not occur when publishing new services.
To resolve this issue, navigate to the old arcgisinput folder, copy the existing services' folders, and paste the folders in the new arcgisinput folder location. Once the folders are transferred, existing services can be overwritten and restarted.
