When I test my web service through the XML Web Services tab in the VP8 task pane manager, I get the following error:

Error: 1429 - OLE IDispatch exception code 0 from Client: Client:An unanticipated error occurred during the processing of this request. HRESULT=0x800A13BE - Client:Sending the Soap message failed or no recognizable response was received HRESULT=0x800A13BE - Client:Unspecified client error. HRESULT=0x800A13BE..

This web service does work on my development PC, but on the production server, I get above error.

Also, we are running 2 production web servers on a Network Load Balancer. I have created the identical virtual directories on both PC's and copied and registered both DLLs on both PCs.

What can cause this error?

Thanks,
