I have a VFP8 application that is using SOAP to make requests to a VFP8 COM server running under IIS6.

One particular request that instigates a lengthy process in the COM server fails at the client with the following message:

-----
OLE IDispatch exception code 0 from Connector: Connector:Connection failed or server refused connection (request might exceed MaxPostSize). HRESULT=0x800A151E - Client:An unanticipated error occurred during the processing of this request. HRESULT=0x800A15
-----

The strange thing is that the process runs to completion without any problems in the COM server. The IIS logs show no errors. As far as the COM server is concerned everything ran successfully. For this request, almost nothing in the way of parameters is sent across, so the MaxPostSize shouldn't be an issue.

The error indicates that the connection had problems, but it doesn't appear to be the case since the process in the COM server was instigated and runs fine.

The SOAP ConnectorProperty("Timeout") value is large (1200 seconds) and I've tried adjusting the ConnectorProperty("ConnectTimeout")> to a large value (1200 seconds) as well. While this solved the problem on the WinXP clients, I'm still get the error message on the Win2000 clients.

Does anyone have a suggestion for what can cause this error or how to solve it?

Thanks,
Scott
