WCF Service with vc++6.0 COM dll hosting in IIS RRS feed

  • Question

  • Hi,

    I am working on a product wherein when my main exe runs, I can get value in my specified dll. I had created a Service using WCF and I called that dll. When I’m running the project in VS2010 I can get the values from dll, but if I host in IIS the value returned by the dll is unknown (encrypted) like Â Ì.

    Kindly suggest the needful. Thanks in advanced.

  • Not sure what specific reasons cause this issue, maybe it is permissions problem, you could check whether the VC++ 6.0 com dll will check the caller crdential while WCF service calling this dll, if it is not the local system account of IIS, then it will return unknown encrypted value.
