SYMPTOMS

A computer running Windows NT Diagnostics (Winmsd.exe) may fail after you click the operating system version button. The following error message appears:
An application error has occurred
and an application log is being generated.
WINMSD.EXE
Exception: access violation (0xC0000005, Address 0x021a9720)
In addition, if Drwtsn32.exe is set up to create a Drwtsn32.log, the following text will appear in the header. 
   Application exception occurred:

           App: winmsd.DBG (pid=113)
           When: 8/15/1996 @ 16:14:44.592
           Exception number: c0000005 (access violation)

NOTE: The address and pid you have may differ from those in the example.

CAUSE

When the computer was installed, the date and time of the computer were out of the range supported by the ctime library function in the C language. This function handles dates in the range January 1, 1970 to January 18, 2038 (inclusive). The registry contains an entry that has an invalid Hex number that is out of range. In most instances this value was found to be improperly set to REG_DWORD 0xFFFFFFFF. The following is the registry key that causes the problem: 
   \SOFTWARE\Microsoft\Windows NT\InstallDate

WORKAROUND

To work around this problem, do the following:

WARNING: Using the Registry Editor incorrectly can cause serious, system- wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of the Registry Editor can be solved. Use this tool at your own risk.
  1. Start Registry Editor (Regedt32.exe) and locate the following Registry subkey in the HKEY_LOCAL_MACHINE subtree:

    \SOFTWARE\Microsoft\Windows NT
  2. Select the InstallDate value and change it to a valid Hex Dword representing an appropriate date and time.
    1. Sunday, January 01, 1995, 12:00:00 AM = 2f0636d0
    2. Monday, January 01, 1996, 12:00:00 AM = 30e76a50
    3. Use the registry entry value from another computer.
    4. Write a small C program using ctime to calculate the exact value.
  3. Quit the Registry Editor and run Windows NT Diagnostics.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.5x. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The function name and the instruction with the FAULT will appear exactly as shown below in the Drwtsn32.log file, if the Windows NT Debug Symbols have been set up.
