After you install the Server, open the Computer Management console. (e.g., on the Desktop, right-click My Computer, then click Manage.)
Expand the Local users and groups node, right-click Users, then click New User. The New User dialog box appears.
Create the user account (e.g., GSFTPServer), click Create, then click Close.
Close the Computer Management console.
In Administrative Tools, click Local Security Policy. The Local Security Settings dialog box appears.
Expand the Local Policies node, then click User Rights Assignment.
In the right pane, in the Policy column, double-click Act as part of the operating system. The Properties dialog box appears.
Click Add user or Group. The Select Users or Groups dialog box appears.
Select the new user you just added (GSFTPServer), click Add, then click OK.
If necessary, assign permissions for this user account in Windows.
Assign the server to the new user account and log the server on as a service.
