Here are a few other important points regarding configuration that you should consider:
Install the latest service packs and hot fixes. Microsoft regularly updates Windows NT security features in hot fixes and service packs. While this process has also been known to introduce holes, it is still recommended that you install the latest software.
Remove ROLLBACK.EXE. This application was mistakenly distributed by Microsoft and can destroy essential system files.
Disable floppy and CD-ROM drives on crucial servers.
Use NTFS only. File Allocation Table (FAT) file systems do not have security or access controls. These necessary components of security are provided only through NTFS.
Set Access Control Lists (ACLs) on essential files to allow access to authorized individuals only. The best security mechanisms available are worthless if they are not used. The ACL capability is typically not used to its fullest potential.
