For my company, I created a ASP.NET web service that uses a 3rd party payment prcoessing engine to authorize credit card transactions.
The web service is hosted on a seperate 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)
