NT Backup not working using AT-- permissions problem

For some reason, NT backup isn't working with the AT command. I have the backup hardware set up on my PDC, and it'll back up that information fine. When I schedule a ackup of my BDC I get the message "You do not have permission to access portions of. Please see the owner or administrator to get permission.".
The BDC has a share set up for backup (let's call it backup$). The schedule service is runnign as the Administrator. backup operators, domain admins, and (finally) the Administrator have full control of the backup share. I know that the administrator has permission on every directory, every file on that server. Permission is still being denied.

I checked the advanced user rights and made sure the Administrator had 'em all. Still no good. Am I missing something?

The backup$ is mapped to i: on the PDC. The batch file launched every night is NTBACKUP BACKUP  i: /V /R /B /D "FULL BACKUP" /L "C:\LOG\LOG.TXT" /hc:on

the AT command was
at 20:00 /interactive /every:m,t,w,th,f,s cmd /c c:\bkupfull.bat

Any ideas?

What kind of access do users access the directory remotely have:
try setting it like this:
NETWORK  Read
if it doesn't work try full control.

Good luck

The Administrator has full control of the share and the directories. I know I can read all of the files. I know that the schedule service is running as the administrator, but it's almost as if the backup itself is running as another user.

make sure that only users who has rigths to

I'm afraid that account already has those rights. Any other ideas?

do you know about object you dont can access too?
I think this can be profiles stored on this BDC because of this will be created with rigths to owner only. Administratros AND system are excluded from this.
On my machines i take over owner ship of all to admin and give full control to user and read access to admin and system.

hope this helps

The schedule account, which is  doing the backup, is the owner of the directories, and has full permissions on them. Guess I'll have to call Microsoft today.

Tip: schedule a cmd w/ option 'interactive' - once it fires, you have a command prompt reacting quite like your scheduled job would. Anything you start from here works under the schedule account. In general, buying BackupExec or ArcServe is far better than AT-scheduling NTBACKUP. Last thought: Run the schedule service under the system account, then let the batch file first establish the needed network connections (net use X: \\computer\share password /USER:domain\user), call ntbackup then delete the connections. Drive letters used in the batch MUST NOT exist or be mapped by the logged-in user, but the account used is independent. Lastly, you could set up the share used for backup as a null share on the BDC gravely compromising security.

Heh - have had enough probs with scheduled jobs. Scheduling VB apps - scheduling Access - etc. I even have a machine running two copies of the scheduler under different accounts! The one thing I have had no luck with is sending an email from a scheduled Access code. That scheduled cmd trick I offered is invaluable - e.g. to set up an exchange profile for the system account!

How did you set up the multiple schedule account?
