SYMPTOMS
========
External may report the following error in the SESSION.LOG when you try to send
a mail message to a local area network (LAN) connected postoffice:
A critical error has occurred
Error Code=1005, Device Error=000c
CAUSE
=====
This error is not an External related error. The External program is returning
an error generated by Interrupt 24h in MS-DOS (Critical-Error Handler). This
could have originated from MS-DOS or from the network shell, if a network drive
is involved.
In most cases where External gives an error code of this nature, it indicates a
problem accessing a network drive.
RESOLUTION
==========
The Error Code= value consists of four digits. The last two digits are the most
useful for identifying a problem affecting the External program. The hex values
of 00 through 1A correspond with drives A through Z (00=A, 01=B, ..., 05=F, ...,
0C=M, ..., 1A=Z).
The Device Error= value is passed from the contents of the DI register, and only
the lower byte of the DI register is valid. If the Device Error= value is not in
the following table, it may be an invalid register entry that is getting corrupt
in the process of generating the error.
Error Code Meaning
-----------------------------------------------------------------------
00h Write-protected disk
01h Unknown unit
02h Drive not ready
03h Invalid command
04h Data error (CRC)
05h Bad request structure length
06h Seek error
07h Non-DOS disk
08h Sector not found
09h Printer out of paper
0ah Write fault
0bh Read fault
0ch General failure
0fh Invalid disk change (DOS 3 & later)
The three most common Device Error= values returned in External are as follows:
Device Error=000c (General failure)
Device Error=0002 (Drive not ready)
Device Error=000A (Write fault)
In this case, Error Code= 1005, Device Error=000C would translate to a general
failure reading drive F:.
