DOCUMENT:Q150275 08-AUG-2001 [winnt] TITLE :Redirector Doesn't Close the Session After User Logs Off PRODUCT :Microsoft Windows NT PROD/VER:winnt:3.5,3.51 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation versions 3.5, 3.51 - Microsoft Windows NT Server versions 3.5, 3.51 ------------------------------------------------------------------------------- SYMPTOMS ======== On Windows NT, it is possible for multiple logon sessions to be in progress simultaneously from a single workstation to a single server, for example an interactive logon session initiated by the interactive logon user and another session initiated by a service. These logon sessions are multiplexed over a single virtual circuit (VC). If a resource is kept open by the noninteractive session on the server, the server will keep open the session for the interactive user even after the user has logged off from the workstation. CAUSE ===== When a user logs off, the Rdr.sys checks to see if there is any open resource for that user. Rdr.sys will close any resources that are open with the session ID of the currently logged on user and then send a logoff request to the server; the server will then close the session. However, if a resource is open on a noninteractive session, Rdr.sys will close the resources open by the interactive user but will not send a logoff request to the server. As a result, the session will be kept open for the user on the server even after the user has logged off. RESOLUTION ========== Use the hotfix mentioned below. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT versions 3.5 and 3.51. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack.
