To change the permissions of a folder on the nt server you must log into an nt workstation.  When you have logged in navigate to the folder whose permission you want to change and follow the instructions below.

1.) High light the file by clicking on it once.

2.) Click on the "File" option on your menu bar and select properties.  A window called "filename Properties" should appear.  Select the Security tab.  the "properties" widow should look similar to the picture below.


 

3.) In the "properties" window click on the permissions button.  This will display the current security settings for the file and give you the option to change those setting.  There should be at least two settings already associated with the file.  One entry for "Administrator" and one for "Backup Operators".  You should not change these settings.
 
 

4.)  To give a user permissions to a file, click the "Add" button.  A window called "Add Users and Groups" will appear.  By default users do not show up in the window.  To show users click the "Show Users" button in the "Add Users and Groups" window.
 
 
 

5.)  To select a user double click on the username displayed in the "Names" section of the "Add Users and Groups" window.  That user name should appear in the "Add Names" section as depicted above.  After the user is selected choose the appropriate access options from the "Type of Access" pull down menu.  For information about file protections read the section below entitled "NTFS File Permissions".
 

NTFS File Permissions
These permissions define how a file can be used and accessed. The FIVE predefined file access permissions are

The following table summarizes each of the rights associated with the file permissions defined above.
Permission R X W D P O
No Access            
Read Yes Yes        
Change Yes Yes Yes      
Full Control Yes Yes Yes Yes Yes Yes
Special Access (any combination) Yes Yes Yes Yes Yes Yes 
                R       Display the file’s data, attributes, owner and permissions
                X       Execute the file
                W       Write to the file or change it's attributes
                D       Delete the file
                P       Change the file’s permissions
                O       Take ownership of the file
When an NTFS partition is created, Windows NT Server assigns Full Control rights to the group Everyone. This means all users (including network users) have unrestricted access to any data stored on that partition. Network Administrators might alter these settings to provide additional security. Please note that users would be required to either have access to the local computer (and if it's a domain controller, they do not have logon rights by default), or a share has been created which gives the users access permissions.
