Question

I have a PC with a WCF service localhosted, I can add a reference to the service in a C# program. However when I run the program, I get an Access Denied error. I get no other information apart from Access Denied.

Does anyone have any suggestions on what to do. I have another machine which looks the same set up but am able to connect to the localhosted version on the same machine. I’ve looked at other questions already posted but nothing seems correct.

Edited….

Answer 1

Found out what the problem was and quite laughable. Whilst I thought it was IIS or .NET the cause, I was as close to the problem as a bargepole. The problem was that the Windows Firewall was set to block everything including network traffic. Question was posted here because I thought it was .NET code.

Thanks Grzegorz, CodeCaster amd Shailesh for spending the time to read and provide suggestions.
