PROBLEM
Starting a map service or creating a new service after upgrading to ArcGIS 9.3.1 when also using ArcGIS Server ArcPad 8.0 Extensions returns the following error:
"Unable to Start service.
Error (Server object instance creation failed on all SOC machines. Server Object instance creation failed on machine <machine_name>. CLSID for Type MapServer is not registered)."
However, map services with ArcPad 8.0 Server capabilities do operate without problems and without error. This behavior did not occur prior to installing the ArcGIS 9.3.1 upgrade.
Installing ArcGIS Server ArcPad Extension 8.0 on an ArcGIS 9.3.1 configuration results in corruption of existing ArcGIS Server map services. All map services are stopped and are unable to be restarted. New map services cannot be published.
