Question

What should be done if the Unknown ArcIMS Service error appears in the viewer?

Answer

If you have upgraded from ArcIMS 3.1/4.0 to ArcIMS 4.0.1, there is a possibility that you will receive the error "Unknown ArcIMS Service" when trying to view your Web site.

One solution to this problem is to delete your existing serialization files (ArcIMSFolders.sez and ArcIMSSite.sez) and allow ArcIMS 4.0.1 to re-create them.

A. Open ArcIMS Administrator and record the following information for each Map Service that was previously created, since each Map Service needs to be re-created:
- Name (Case Sensitive)
- Map File Location
- Virtual Server

B. Navigate to the directory <drive>:\Program Files\ArcGIS\ArcIMS\AppServer and delete or rename the following two files:
- ArcIMSFolders.sez
- ArcIMSSite.sez

C. Open the Windows Services panel and stop the three ArcIMS Windows services in the following order:
- ArcIMS Tasker
- ArcIMS Monitor
- ArcIMS Application Server

D. Open the Windows Services panel and start the three ArcIMS Windows services in the following order:
- ArcIMS Application Server
- ArcIMS Monitor
- ArcIMS Tasker

E. Open ArcIMS Administrator and re-create each Map Service that was recorded in Step A above.
