In order to author metadata for map services, you must manually edit metadata and copy it to the appropriate virtual directory on the web server.
Create a virtual directory named Metadata.
Use ArcCatalog to create a template metadata file. Use this file to generate each metadata file for your ArcIMS services.
Create metadata files.
