I have an odd problem. I have a site where I'm able to resolve ad groups that no longer exists. I can see them if I search in the people picker or I can type it in and resolve it just fine.
If I try the same in another site collection (central administration) I can't find them using the people picker, and I can't resolve them.
Anyone know how to "resync" with AD in the site collection where I'm able to see nonexisting ad groups and users?
