When I'm troubleshooting issues I find in Event Logs, one of the first places I head to is, http://www.eventid.net.  When you go to the site you can enter an EventID and you'll get back a list of EventID's that match along with the various "Source" entries they apply to.  Once you find the issue that matches your event there's a link to click on where you will find a comments and links from others who have encountered the same issue.  This in itself is a great resource, but for a very reasonable fee you can sign up for an account that will allow you to have one-click access to any links referenced in the comments, the ability to set notifications when/if there are updates, no ad banners and more.

The next time you get stuck check them out and if you find value in the site, signup and help them keep it going.
