## SUMMARY

The system clock or Timestamp of the machine running the EXTERNAL.EXE program, MS-DOS Message Transfer Agent (MTA), included with version 3.2 of Microsoft Mail for PC Networks, may be incorrectly incremented by 24 hours, if the BIOS type cannot be detected properly.

## MORE INFORMATION

The ClockRollOver switch may need to be added to EXTERNAL.INI or to the command line, /ClockRollOver, of EXTERNAL.EXE, if difficulty is encountered in recognizing the BIOS type and date of the machine it is running on. In version 3.2, this is set to a value of 1 (ON), by default. Setting this to a value of 0 (OFF) will keep External from touching the system BIOS and should resolve the problem.
A way to check if you will encounter this problem is by running MSD.EXE, Microsoft System Diagnostic utility, on the MTA machine. This can be accomplished by selecting the option Computer from the main menu after the utility is started. If it recognizes the BIOS, you probably do not have a problem, but if it does not then mail administrators should be aware of a possible need to include this switch at startup.
