Hi,

I have a Windows 2003 server, and Windows 2003 terminal server with the
following scenario.

I have a folder, with share permissions allowing full access to:

Domain\users

And I want to deny one specific user, so i setup a DENY entry.

I have found this did not work. The above "allow" is inherited, whereas
the DENY was not. The DENY should have overridden, but the user
continued to have access to the folder.

I have found however, changing the allow to :

Domain\Domain users

Does continue allowing access, however, correctly (as far as I
understand) DENY's the user in question access.

What am I doing wrong here, or is this a bug?

Allow me to correct the above.
The share permissions are "full" to everyone.

I am using NTFS permissions.

Did you ask user to logoff/disconnect from the share after you made changes?

Hi Daryl Lufor from mauriitus

the following rules should be apply according to me

remove the Everyone group from the Share permissions

on the ntfs permissions remover every users and group

then add the authenticated users group and assign your full control

then add the "user" :( i always recomment the A G DL P Strategy so put the
users in at least a Domain Local group and call the group Deny access to
folder X then deny access to that group

check if yu have sub folders or file that permission inheritance check box
is checked

Cheers

Double check how the user is authenticating to that share/server. If
persistent alternate credentials are used for a mapped drive or stored
credentials for XP Pro the user may not be authenticating as himself. Next
time the user is connected to the share you can use Computer Managed/shared
folders-sessions to see what users are connected to the share and from what
computer. If that does not help use xcacls.vbs to enumerate permissions for
the folder and post results in a reply. Also check the users "effective"
permissions in the advanced page of security properties for the folder and
compare results to a server where you are not having the problem and make
sure the user in question is not owner of the folder.

Yep. Rebooted the machine several times, though I don't think this
should matter.

I'm still replicating it on other servers successfully. Create a file
with these permissions:

Domain\Users ALLOW FULL
Domain\Bob DENY FULL

Logon as Bob. You will have full access to everything, despite DENY
supposed to being an override.
