My first guess is that Blat is not in your search path, and that you might
need to specify the full path to blat.exe in your task scheduler, plus the
full path to any files being used.

My second guess is that you do not have the SMTP server configuration saved
for all users to access in the registry.  When Windows scheduler runs, it
may run as the user account named "administrator" rather than as you.  If
you stored the Blat server configuration using the -hkcu option, or if Blat
was forced to store the information under the registry tree
Computer\HKEY_CURRENT_USER, then this information may not be available to
the Blat invocation from Windows scheduler.  This can be checked by opening
regedit.exe, and searching for "Public Domain".  Ideally, you want to find
"Public Domain" listed under
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node (if using 64-bit Windows),
or Computer\HKEY_LOCAL_MACHINE\SOFTWARE (if using 32-bit Windows).

If you need to use 3rd party services for SSL/TLS encryption, such as
stunnel from stunnel.org, then make sure this 3rd party service is always
running.  If it is not running when your schedule task begins, then this
would prevent Blat from running.
