DOCUMENT:Q142847 08-AUG-2001 [winnt] TITLE :Bugcheck 0x1e Caused by Isotp.sys Driver PRODUCT :Microsoft Windows NT PROD/VER:winnt:3.5,3.51,4.0 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0 - Microsoft Windows NT Server versions 3.5, 3.51, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When the ISO TP4 protocol runs (Isotp.sys, available from the Windows NT Driver Library), you receive the following error message: STOP: 0x0000001E (c0000005 00000002 00000000 00000002) KMODE_EXCEPTION_NOT_HANDLED CAUSE ===== Under certain conditions, when TP4 protocol data is received fast enough that the messages need to be queued for later processing, a function is called incorrectly, causing this STOP message. This problem is somewhat dependent on the network traffic patterns. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT versions 3.51 and 4.0. This problem was corrected in the latest Microsoft Windows NT 4.0 U.S. Service Pack.
