Cause

Attempting run a Direct Connect through ArcIMS to a Microsoft SQL Server database requires the Microsoft SQL Server datasource name in the AXL file as a addendeum to the instance name. In other words, the Microsoft SQL Server datasource name should be appended to the instance name in the AXL file. If the correct instance name is not provided in the AXL file, the error listed above is returned in ArcIMS Administrator.

Solution or Workaround

1. Add the correct datasource name. A default installation of Microsoft SQL Server will name the datasource as your machine name.
   
   Edit the AXL file and change the instance parameter for the SDEWORKSPACE tag and append the Microsoft SQL Server datasource name to the instance name. In this example, the machine name is "ganges". To find more about Microsoft SQL Server datasource name, please refer Microsoft SQL Server documentation.
   

   Code:
   <SDEWORKSPACE name="sde_ws_0" server="ganges" instance="sde:sqlserver:ganges" database="data" user="" encrypted="" password="" geoindexdir="" />
