Directory Share Disappears After Computer Restart

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

You are able to configure the security of a sub-directory on an NTFS partition such that if a share is created on the sub-directory, the share disappears the next time you restart your computer.

CAUSE

The following accounts have full control of all directories on an NTFS partition, by default: Administrators, Creator Owner, and System. If you share a directory that is more than one directory below the root (C:\Level1\Level2 for example), and the security permissions on the directory have the Administrator and System accounts removed, the share disappears the next time you restart your computer. It does not matter which accounts are included in the security permissions of the share, only those of the directory.

RESOLUTION

Make sure the System or Administrator accounts have security permissions on the directory being shared.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.1. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
