I created a ASP.NET web service that uses a 3rd party payment processing engine to authorize credit card transactions.
The web service is hosted on a separate application server and connects to the payment processing server via an ActiveX object (.ocx
extension). Lately, it has been generating a HRESULT: 0x80010105 (RPC_E_SERVERFAULT)
exception when I try to establish an connection to the application using an "IsAvaiable
" check.
Does anyone recommend an good place to start for researching this issue?
(I know contacting the vendor would be the first option, but I want to have my "ducks in a row" before we contact technical support)
