FeatureClassNameClass.Open() Error, any ideas?

Question

This code works fine on my Windows 7 64 bit machine, but fails on the target machine, Windows Server Standard SP2 64 bit.

 public List<string> GetShapeFileFieldNames(string shapeFileDirectory, string shapeFileName)
    {
        shapeFileName = shapeFileName.ToUpper().Replace(".LYR", ".SHP"); 

        IWorkspaceName pInShpWorkspaceName = new WorkspaceNameClass() as IWorkspaceName;
        pInShpWorkspaceName.PathName = shapeFileDirectory;
        pInShpWorkspaceName.WorkspaceFactoryProgID = "esriCore.ShapefileWorkspaceFactory";
        IFeatureClassName pFCName = new FeatureClassNameClass() as IFeatureClassName;
        IDatasetName pShpDatasetName = pFCName as IDatasetName;
        pShpDatasetName.Name = shapeFileName;//this is your input file 
        pShpDatasetName.WorkspaceName = pInShpWorkspaceName;

        IName sourceName = (IName)pFCName;
        IFeatureClass sourceFeatureClass = (IFeatureClass)sourceName.Open(); //HERE IS THE ERROR
        IFields sourceFields = sourceFeatureClass.Fields;
        return GetFieldNames(sourceFields);
    }

Exception from HRESULT 0x80040351 at ESRI.ArcGIS.Geodatabase.FeatureClassNameClass.Open()

I converted the HRESULT into decimal, 2147746641, and ran it through Google

• 2147746641 ESRI
• 2147746641 Constants

No results.
