some tips

• Simple File Sharing is a feature introduced in Microsoft Windows XP. Simple File Sharing removes some file sharing security options available in other versions of Windows. This helps Windows XP administrators quickly set up folder shares

• Enabling Simple File Sharing prevents the ability to assign user-level passwords to shares. When Simple File Sharing is enabled on a computer, remote users will not be prompted for a password when accessing that computer's shares.

• If the Windows XP Professional computer is part of a Windows domain rather than a Windows workgroup, this process for enabling or disabling Simple File Sharing has no effect. Simple File Sharing always remains disabled for computers joined to domains.
