Cause

When .NET Service fails to load, it opens up multiple instance of the process and occupies the port / socket without planning to terminate.

Resolution

1. Access Denied:

Make sure the logon user for the .NET remoting service has full access rights to this directory:=
Ensure windows explorer can see hidden folders:
C:\Users\[User Profile]\AppData\Microsoft\Crypto\RSA

2. Pre-occupied port/socket.
   Kill the process to free up the port /socket. 
   Run command prompt as system administrator, then execute below two lines.

taskkill -f -im a4wnetMgrService.exe

taskill -f -im a4wnetsvHost.exe
