Ok so getting the error:
The attempt to connect to http server/powershell using 'Kerberos' authentication failed: Connecting to the remote server failed with the following error message: access is denied.
Rebuilt the virtualdirectory, verified the applicationhost.config file contained the correct path to kerbauth.dll and wsman.dll
Also the two user accounts Ive tried do have remote powershell enabled.
the kerbauth module in the powershell virtualdirectory does not have a path value, and it is listed as managed. I know that usually means that the applicationhost.config file has an incorrect path.. but i can assure you the path is correct. I even copied the kerbauth.dll file into c:\program files\microsoft\exchange\v14\bin (when my exchange install path is c:\exchange\v14
I also verified my ExchangeInstallPath env variable does say c:\exchange\v14 which is where my exchange is installed to.
I've ran iisreset /noforce multiple times before, during and after.
