 WIn2k Server. Single Server in system. Using Active Directory. When I
click on Properties of a shared folder and click on Security, Some of the
User Names are there and some are replaced with a string of numbers and
letters. The Icon is greyed out and has a question mark. Some users cannot
access thier data in these folders. What is causing this and how do I fix it?

 In a single server, single domain Active Directory this usually means that
the user or group no longer exists, hence the SID cannot be translated
to a display name. The same happens in a stand-alone. In a multi-server,
or multi-domain environment this can be a problem with trust connectivity.
Are you seeing any "custom" user or groups, by which I mean anything
other than well-know built-ins (like Administrator, Users, Authenticated
Users, etc.) being shown - I mean if there is a group named Finance or
a user Charlie, do you see any such that are defined post-install ??

We have three custom groups in this directory. I am seeing one of them but
not the other two. Also, the customer has been messing around with it as
well. I'm not sure what he has done. If he deleted the groups and recreated
them, would this happen?

Thanks,

Yes, that would be able to account for it.
A delete and redefine by same name results in new group with
different SID, but all grants are in terms of SIDs so they point to
old, no longer existing, group.

If you delete and recreate this will happens...
These numbers are SID, they are unique. When you create a group or user, the
system add a Sid to the user or group...
The system only see and uses the SID, the system don`t care about real
names,the names existis just for convenience to users and administrators.
When you delete a user called John, and recreate it, the "new" John has a
new unique SID, so you must add him to yours shares permitions, for example.
This is a security question, because if only one user has acess to
something, no one can create a new user with the same name to gain acess
again....
