DOCUMENT:Q161802 09-AUG-2001 [winnt] TITLE :Stop 0x0000000A During Create File SMB PRODUCT :Microsoft Windows NT PROD/VER:winnt:3.51,4.0 OPER/SYS: KEYWORDS:kbenvkbbuglist kbfixlist ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation versions 3.51, 4.0 - Microsoft Windows NT Server versions 3.51, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== Windows NT Server may trap when LAN Manager 2.x compatible clients with oplocks disabled attempt to open a file that is already in use by a client that supports oplocks. The following stop message may appear on your Windows NT server: STOP 0x0000000A (0x00000104, 0x00000002, 0x00000001, 0xfbd6bde0) NOTE: Although the last parameter differs depending on the system configuration, it will fall within a protocol driver. In this case, the Stop occurred in Nbf.sys. CAUSE ===== LAN Manager clients that have oplocks disabled can trap a Windows NT 4.0 server because I/O requests submitted to the transport may get queued and completed after the server has already reused the I/O request structure. This issue is unique to LAN Manager compatible clients because it requires the create file Server Message Block (SMB) request to occur. RESOLUTION ========== Code was added to Srv.sys to allow create file requests from non oplock clients to gracefully timeout before reusing the IO request. It is also possible to workaround the problem by enabling oplocks on LAN Manager 2.x compatible clients. STATUS ====== Microsoft has confirmed this to be a problem in Microsoft Windows NT version 4.0. This problem was corrected in the latest Microsoft Windows NT 4.0 U.S. Service Pack.
