Can anyone help me? I cannot start the Windows Firewall. When i try to, it asks me if i would like to start the Windows Firewall/Internet Connection Sharing (ICS) service. When i click yes, it says it cannot start the service. When i try to start it in services and command prompt, i get an error: A system error has occurred. System error 5 has occurred. Access is denied. Is there a way around this or to fix this?
