User has group permissions to object, but still denied access.

[Project Orca]

The user is attempting to change some queries on a database stored on a
server and accessed by a mapped drive, but gets the following error message
when trying to save the changes: "You do not have the necessary permissions
to use the '<query>' object. Have your administrator or the person who
created this object establish the appropriate permissions for you." (replace
the <query> with the name of the query currently being edited). There are
about 80 queries in the database, and I haven't been able to find a pattern
for which queries she is able to edit and which ones she is not.

If she copies or moves the database to her local machine, she's able to make
changes to any of the queries.

Regarding the security, the database was converted from an Access 97
database with no security to an Access 2000 (when connected to a workgroup
file - database.mdw as user "sysadm" ) and then to Access 2003 format (again
with the database.mdw and user "sysadm"). At that point, all of the objects
in the database had an owner of "sysadm".

Then the security permissions were set on the database. The Users group was
only given permission. Another group was created for basic read/write
(GroupRW). The Admins group was given full permissions. The Admin user was
removed from the Admins group. Sysadm was already in the Admins group, the
GroupRW and Users group. User1 had the same groups (Admins, GroupRW, and
Users).

The user has full control of the folder on the server where the database is
stored, as well as propagating that full control to the database files (mdb,
ldb, and mdw).

The way I understand the security as it is set up, even though the
individual users don't have permissions to database objects, they should
still get the permissions that were assigned to their group - in this case
full permissions for User1 since she is part of the Admins group and the
Admins group has full permissions to all database objects.

Can anyone see a reason why she wouldn't be allowed to edit a query? Can
anyone see a reason why she can edit some queries but not others (when they
all have the same security structure)?

I don't want to muddy the waters but it may be important to note that there
35 forms, 45 reports, and 2 macros. She's unable to gain exclusive access to
change reports and forms when the database is located on the server - even if
she's the only one in the database at the time and the server reports no
other users with the database open. This is another issue that I need to
resolve, but I'm trying to tackle one area at a time...

Thanks for the heads-up on the file names! That fixed my second issue.

I'm still scratching my head over the first issue though. She's not using
different databases - I've made sure that I'm using the same database and
workgroup file in my tests under her username. I test them on the mapped
drive and she's unable to edit a few specific queries (security on those
specific queries is identical to queries that she does have the ability to
edit). I copy the files (mdb and mdw) to the local PC, reopen Access, attach
to the local mdw file, close Access, reopen Access and open the local mdb
file and I can edit all queries.

I checked the object dependencies for those queries, thinking that they may
be required for the reports that she couldn't edit (due to the mdb and mdw
file names being identical), but there was no common dependency among the
queries that she couldn't edit. The problem also continued after I changed
the name of the workgroup file.

After a bit more testing, I've been able to rule out some of the variables.
For now, discard the questions of network quirks, Active Directory
securities, and file locations. There is a set of 13 queries out of the 81
that she is never able to edit, regardless of where the database files are
located at. She's also unable to edit them when given explicit full
permissions to those query objects.

Here's the kicker though - the owner, sysadm, can edit the query, but it
doesn't have the ability to change the owner of the object to someone else.
The owners for the other 68 queries can be changed.

I have a gut feeling, based on the names of the queries, that these queries
may have been some of the original queries created in the database. I
thought that perhaps they were corrupted somehow in all of the upgrades and
such. I did a compact and repair on the database, but that didn't resolve
the issue.

Any ideas based on the new information?

It sounds to me as though those queries were created while using a different mdw file. When you look at the owner of the query(ies), what does it say? (this shouldn't matter, except would explain why sysadm can't change the owner).

Are these queries RWOP? What kind of editing is she trying to do - i.e. adding tables/fields which she doesn't have permission to will fail, even though she has modify permission on the query.

Does this query have any lookup fields in it? Do any of the underlying tables have lookup fields defined?
