Can I set up an FTP site with different levels of access for different users?
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1
To limit access to only certain computers
In IIS Manager, right-click the FTP site, and click Properties.
Click the Directory Security tab, and click Edit.
You can assign or deny access to all computers or subnets except those you specify.
On an NTFS file system, you could also use a single virtual directory and set the NTFS permissions to assign or deny different types of access to different Windows user accounts. For more information, see Isolating FTP Users.
