Hi
Please be advised I have managed to resolve this issue. The problem was mine, after many hours of troubleshooting I discovered a typing error, sigh ............
I am getting a error message of 'Object reference not set to an instance of an object' when trying to map a drive. I have done some research and it appears it may be an IIS issue.
I installed HAP as per youtube clip HAP+ Windows Server 2012 Setup
I look forward to any an all troubleshooting tips to get this resolved.
