Incorrect Date Generates an Exception Error in NTBACKUP

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

The Windows NT Backup utility (NTBACKUP.EXE) generates the following error message when the system date is greater than the year 2070:

   An application error has occurred and an application error log is being
   generated.

                        NTBACKUP.EXE
   Exception: access violation (0xc0000005), Address:0x0182aa2d

CAUSE

NTBACKUP uses the clib function time(). The initial release of NTBACKUP did not check the return value and if the year is out of reach, this function returns 0 (zero).

RESOLUTION

To work around this problem, change the date to the current year or to a year earlier than 2071.
