Here are some ideas for getting out of simple file sharing mode in XP
Method 1
Booting the computer in safe mode will reveal that Windows XP Home does indeed still function on traditional NTFS security. In safe mode, right-clicking on a file/folder and choosing Sharing and Security will display the properties sheet for the file/folder, but you will also notice that the Security tab is now present as well. While this method will work, it is not recommended since any security changes made in Normal mode will overwrite the changes that have been made in safe mode.
Method 2
The second method for accessing NTFS security in Windows XP Home is through the CACLS.EXE utility. This utility comes with XP Home and is used for changing the Access Control Lists (ACLs), which are used by Windows to keep track of user permissions/security. Type CACLS /? at the prompt for more information on using this utility. This is the method I have chosen to include in the guide.
Method 3
This is the long term method of choice for setting user security permissions in Windows XP Home via the GUI. It is very easy to install and will bring back the Security tab in Normal mode.
1.) Download the NT 4 Security Configuration Manager from
http://www.microsoft.com/ntserver/nt...cm/default.asp.
2.) Run the scesp4i.exe file and extract all files to a temporary directory.
3.) Right-click on the setup.inf file and choose the install option.
4.) Answer no if asked to overwrite essent.dll.
