Hi, I'm experiencing this strange problem.
On a NT SERVER 4 machine I have two NTFS partitions.
I set first the sharing permissions on these partitions in order to allow access to only some groups and than I used the security tab to set file and directory permissions, over all subdirectories.
Then was evening and it all worked fine.
The next day I have made a check on this server and I discovered that the security tab is disappeared, clicking the right mouse button on the directory on whichI need to reset or modify permissions.
In other words the system treats the ntfs partition like fat partitions after I've set them.For example I cannot set auditing anymore, even if I'm logged on the server as administrator. Is it normal or strange? Is there anybody that can tell me how to resolve this problem?
Thank you very much!

Sounds like you've locked yourself out. When you assigned the NTFS permissions (security tab) did you remember to add your Administrators group with a full control permission? Sounds like you forgot it.
Two ways of recovering:
1. Restore from a backup that was taken before the NTFS permissions were altered.
2. Try bringing up the security tab on the root of the drive, if you can. If so, add the administrators - full control there, and make sure that the small "apply to subdirectories" box ischecked, then click OK. This may only restore your security tab on the root folders, you will probably have to then go into each root folder and repeat the permission assignation, then to each sub folder etc.If you get an error that says "unable to re-set the permissions on ____" take not of the file or folder name. You will need to take ownership of these objects before they will allow you to re-set permissions on them.

NOTE: Also make sure that the system account has full control access onALL files and folders.

Good luck,

Ian

Gian, Login as NT Admin to your domain, Go to the NTFS partitioned HDD, right folder & in "Security", click "Ownership", then click "Take Ownership". This will give you (Admin) permissions to the NTFS folder. Now in "Permissions", add users with permissions for "change" to your domain users & admin. Also make sure you click "Replace permissions on subdir" as well.
Viola !! it will work.

Unfortunately I cannot see anymore the "security tab" (is disappeared), this is the problem, neither right-clicking on the partition's letter and on any subdirectory.
Thank you
