DOCUMENT:Q137287 08-AUG-2001 [winnt] TITLE :Windows NT Backup Causes Access Violation When Started PRODUCT :Microsoft Windows NT PROD/VER:3.50 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 ------------------------------------------------------------------------------- SUMMARY ======= When you start Windows NT Backup (NTBACKUP.EXE) a Dr Watson Access Violation error appears. CAUSE ===== This error can be caused by corrupt log files in your %Systemroot%\system32 subdirectory. Catalog files are used by Windows NT Backup to sort the cache information from the tape. RESOLUTION ========== To correct this problem, locate a file with the .Uxx extension (where xx is the number of the backup tape used during a backup session) in the %SystemRoot%\SYSTEM32 directory. Rename or delete the file and re-catalog the tape. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT version 3.51. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
