DOCUMENT:Q192297 16-MAY-2002 [winnt] TITLE :Applications May Fail with Access Violation During File Open PRODUCT :Microsoft Windows NT PROD/VER::4.0 OPER/SYS: KEYWORDS:kbWinNT400sp5fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 4.0 - Microsoft Windows NT Server version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When a non-administrator opens a file from within an application such as Microsoft Paint, an access violation (AV) could occur causing the application to terminate. Restarting the system is required to clear the problem. The AV occurs in the MFC DLLs. The problem does not occur if the user is an administrator. CAUSE ===== If Shell32.dll is invoked before Rpcss.exe, shell calls CreateEvent() to create a certain event. An incorrect parameter passed on this call adds restrictions (security) on the event object. The problem does not occur if Rpcss.exe initializes first because the right parameters are passed on the call to create the same event. RESOLUTION ========== To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to: - http://www.microsoft.com/windows/servicepacks/ -or- - Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack For information on obtaining the individual software update, contact Microsoft Product Support Services.
