Enabling Act as part of the operating system local security policy
On servers running Windows 2000, you must enable the Act as part of the operating system local security policy for the WS_FTP Server user account in Windows if you want to use Microsoft Windows or Microsoft Active Directory user databases. If you are upgrading on Windows 2000 with a WS_FTP Server host that uses Windows NT user database, you must set this policy for the user account under which you are logged in when you run the install program.
Note: Domain-level security policies override local security policies.
To enable the Act as part of the operating system security policy for a user:
From the Start menu, select Control Panel. The Control Panel opens.
Double-click Administrative Tools. The Administrative Tools folder opens.
Double-click Local Security Policies. The Local Security Settings console opens.
Expand Local Policies, then select User Rights Assignment.
In the pane on the right side of the window, double-click Act as part of the operating system. The Act as part of the operating system Properties window opens.
Click Add User or Group. The Select Users or Groups dialog appears.
Select the users for which you need to enable the Act as part of the operating system local security policy. When you are done, select OK.
To ensure the changed policies are in effect, restart Windows.
