If you are attempting to uninstall the Symantec Web Security Service Auth Connector and you receiving errors
The error is likely the result of the DHCP Client Service locking the Auth Connector file (BCCA.EXE).
Windows Server 8 Pro
Go into services and stop the DHCP client service. This allows you to finish uninstalling the service.
