I have a .Net web service that runs a custom ArcToolbox model. It works fine when running from the .Net IDE. But, when I publish the web service and run it from a browser, the GP.Execute call fails. Any ideas why this fails once the web service is published?
The error message is
Error HRESULT E_FAIL has been returned from a call to a COM component.
Private Sub TestCustomGPModel()
Dim GP As ESRI.ArcGIS.Geoprocessor.Geoprocessor = New ESRI.ArcGIS.Geoprocessor.Geoprocessor
Dim pResult As ESRI.ArcGIS.Geoprocessing.IGeoProcessorResult
Try
Try
GP.AddToolbox("C:\mySimpleToolbox.tbx")
Catch ex As Exception
Throw New Exception("Can't find toolbox.")
End Try
Dim parameters As IVariantArray = New VarArrayClass()
Dim strToolName As String = "mySimpleModel"
Try
pResult = GP.Execute(strToolName, parameters, Nothing) ' *** Error here
Catch ex As Exception
Throw New Exception("Error executing tool.")
End Try
Catch ex As Exception
Throw New Exception(ex.Message)
Finally
GP = Nothing
pResult = Nothing
End Try
End Sub

I gave the ASP.net and IIS guest accounts Admin permissions and this also made no difference.
Please, any other suggestions would be greatly appreciated.

I am not sure how to do it but one idea would be to see if you can have your web service run using your interactive account. I am not suggesting that you deploy this way but merely implying that if it works then you have more information.
To give an example (not IIS specific), many times services run using the System account. The System account is very powerful on the local machine but has no priviledges to access information on the network.
