On having a look in the event viewer - system I have a regular error message concerning service control the event number is 7023 which applies to the IPSEC services. I then went to the Services page and saw that IPSEC services was set to Automatic but it had not started, I clicked on it and got the following message 'Could not start the IPSEC services service in local computer Error 1747. The authentication service is unknown. Do I have a problem here please and what action if any is needed. Thanks.
