I am getting issues while connecting to wireless networks. If I am trying to run Network Diagnostics and Repair then I can see a message that says "The dependency service or group failed to start", and after that I will get "Network Diagnostics cannot run because the Diagnostics Policy Service is not running." So after when I open Service Control Manager and try to start the service manually then I will get some message "Windows could not start the Diagnostic Policy Service service on Local Computer. Error 5: Access denied." After that I try to connect to Wireless Networks again then I am able to connect to the network but unable to access the internet. I am using only one admin account on this computer? Can anyone tell me how to solve this issue? Thanks.
