How to fix DCDIAG errors on windows server

After running DCDIAG in one DC I found some bunch of error. I am not sure how to troubleshoot the same. The first test has give out error like frsevent. This is somewhat related to shared items. But now the errors are increasing. I am having more domain controllers in my network. I need some easy to way to deal with this errors. I do not think I will be having time to troubleshoot each of them one by one.

I do not think there is any automated service that can do this job. You have to post each of those error one by one and fix them. You an go in Event Viewer where you will find more description on the same. On the basis of that you can search Microsoft help articles on the web and use it for fixing the problem. It looks you had performed this test after a very long time.
