I have a problem trying to sync 2 of my servers with the DC's. Every time I try to start the Windows Time service I get an error saying the logon service is not running, however it is. This a problem on 2 of our servers and is starting to cause problems as the backups are failing and one the machines is our file server. I have searched the net and found nothing so any help would be appreciated. I've tried various w32tm command and they return errors, I think because the service hasn't started. Please have a look at the screen shots below and let me know what you think. Regards
