MSD files fail to start when created, giving an error. However, MXD services start without a problem.
The possible error messages are as follows:
- "Server object instance creation failed on all SOC machines."
- "Unable to instantiate class for xml schema type:CIMDEGeographicFeatureLayer"
The XmlSupport.dat file in the <ArcGIS Install Directory>\bin folder is corrupted.
The solution to this problem is to replace the XmlSupport.dat file with a copy of one that is not corrupted.
