one of our site collection is getting locked once every few days, then i have to manually go to central admin and unlock the site, why the site is getting locked and how to resolve this issue.

Hi, Not sure this will help or not. http://blog.tylerholmes.com/2008/09/access-denied-for-site-collection.html Thanks

Hi Mimi up, I’m sorry I can’t get enough information about this issue from your description. Could you please give some more information about it? For example, what error message or notice it gave after the site was locked? Is it because of permission problem or other problems? Regards.
