DOCUMENT:Q243469 06-AUG-2002 [winnt] TITLE :Cluster SMB Share Resource Causes Momentary Disconnection PRODUCT :Microsoft Windows NT PROD/VER:winnt:4.0 SP4,4.0 SP5 OPER/SYS: KEYWORDS:kbWinNT400PreSP7Fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server, Enterprise Edition versions 4.0 SP4, 4.0 SP5 - Microsoft Cluster Server ------------------------------------------------------------------------------- SYMPTOMS ======== When you share folders on a shared cluster drive with the Share Subdirectories feature introduced in Service Pack 4, some or all of your folder names may end with a dollar sign (for example, $). Because these shares are automatically hidden, you are not using the Hidden option for the file share resource itself. In this situation, users connected to these shares may be intermittently disconnected. CAUSE ===== When a change in the folder structure is detected, Cluster Server scans for folders that have been deleted to remove the appropriate share. When a dollar sign is used as the last character in a folder name, Cluster Server assumes that it created the share as a hidden share. Therefore, it scans for the folder name without the dollar sign and removes the share when it cannot find the folder name without the dollar sign. Then, the folder is shared again when Cluster Server scans for new non-shared folders.

To create the shares as hidden, use the Hidden option in the file share resource instead.
