SYMPTOMS
When you run the Mail Multitasking MTA for Windows NT (NT MMTA) as a
service, and you manually start an eighth instance where some or all
instances are configured for Single Postoffice, you will get the following
error message:
Error 2140: An internal Windows NT error occurred.
CAUSE
When the drive letters are selected for the instances, two drive letters
are skipped between instances. This happens even if the instance is
configured as a Single Postoffice instance.
For example, on a computer with one floppy drive A:\ and G:\ as the first
available drive letter, the first instance of the Mail External program
will use drive B:\ as the HomePO. Drives G:\ and H:\ will not be used. The
next instance will use drive I:\ for the HomePO; the third instance will
use L:\. The fourth instance will use O:\, the fifth R:\, the sixth U:\,
and the seventh X:\. When you try to start the eighth instance, you will
get the above error message.
WORKAROUND
Use only seven instance when you run the Mail External program as a
service.
If you need to run more than seven instances, you can start additional
instances by running the Mail External program as an application and use
the DrivesDirectPO option to point to the skipped drive letters.
STATUS
Microsoft has confirmed this to be a problem in version 3.5 of Microsoft
Mail Multitasking MTA for Windows NT. A fix for this problem is in
development, but has not been regression-tested and may be destabilizing in
production environments.
Contact Microsoft Product Support Services for more information on the
availability of this fix.
