One of the pre-requisites that we need to have is WS Management 1.1 component so that we can manage non-windows machines. And most of the time, we just need to download the update and install and voi'la it works.
Not today ... I am working in a customer site which all the servers are hardened. So when I tried to install the update ... it gives me error ... Access Denied ...
Never in my mind that installing an update using Domain Administrator account will give me Access Denied.
After an hour of troubleshooting, I find the culprit. The permission for the registry entry for
only gives Read rights for administrators hence I cannot register the WinRM service into the server.
After getting permission from customer, I set the permission to Full Control and the installation of the update works without any problem.
