Running a defrag on ntds.dit

I had a question running a defrag on ntds.dit. We currently have 2 domain controllers but are experiencing a weird problem. There is a delay in Active Directory Users and Computers. It seems to be intermittent but sometimes you will be browsing around and get hour glasses when click on objects or OU's. This happens even logged into the local server. I'm at a loss of what it could be and thought I may take a crack at running a defrag on the ntds.dit files. I had a question about the domain controllers. We have 2. AD1 and AD2, is it best practice to take them offline one at a time and run the defrag on each? Since the ntds.dit file is not located in sysvol or netlogon I did not think they were replicated between the two dc's. Any advice or suggestions is greatly appreciated. Thank you

Online defrag already happens every 12 hours   http://support.microsoft.com/kb/198793   all the offline defrag will do is reclaim space which is probably not that much in your environment.

Have you run perfmon or SPA   http://blogs.technet.com/b/askds/archive/2010/06/08/son-of-spa-ad-data-collector-sets-in-win2008-and-beyond.aspx

Any errors in your logs?

Thanks

Thank you I was not aware of that. I will look into those tools. I do not see any errors in the event logs anywhere. Thanks

After some additional research I think it may be related to a DNS zone. I have to dig into that and I will also run the perfmon tool. Thanks again for your help.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

ok, that is definitely a good place to look if you suspect issues.  DNS is the backbone of AD.

Thanks
