Folder security issue - sid?

Hey

I have 2 shares on the same server (homedirs)

D:\HomeDIR$\TeacherUser1
D:\HomeDIRu$\StudentUser1

Today all the ACL on the folder under the share D:\HomeDIR$ has change to SID insted of the username.

Under the share D:\HomeDIRu$ all the ACL is normal - showing the username

Please see the attached picture. ADSI edit showing SID and the SID on the folder - whats wrong?

This can happen usually 2 reasons i can think of.

1st - Someone has delete this AD account and the Share has this user added directly to the share without using a group. When you delete a user from AD you will get SID objects appearing under shares that this user once had access to.

2nd - If this particular server does not have the "net logon" server running, it will create SID's on the file shares as the net logon service is used to communicate with AD.

When opening the user object it sats created 2010, so the Users have not been deleted.

The netlogon sevice is running

If I add the user again to the folder the user is added without any problems, but the sid stil remains on the folder.

please compair the User sid with the folder sid.. See attached picture.

It could also be if there is name resolution issue ensure that dns is set correctly.http://abhijitw.wordpress.com/2012/03/03/best-practices-for-dns-client-settings-on-domain-controller/

Have you deleted the user id and created again as this can lead to different sid for new user id even if the name is same.
