How to obtain an ArcIMS authorization file

There are several ways to authorize ArcIMS. You can visit https://service.esri.com to obtain an authorization file (by e-mail, fax, phone, or mail) before installing. You can also register ArcIMS using the post installation setup after installing ArcIMS (this is the recommended method). See ArcIMS Authorization Configuration for registration methods using the post installation setup. If the Internet is not available, you can contact ESRI Customer Service or your local distributor.

ArcIMS Spatial Server requires an ArcGIS authorization file for use. Each new version of ArcIMS requires a new authorization file.
