Tried to apply NT Service pack 6a from Microsoft to a Remotely managed Mail
Server (Needed to install PERL for NT so our accounting package can talk to
Imail). Next thing I know, BIG CRASH. Lost the registry in NT, and I had no
backup. (shame on me). Server is in a housing facility in Los Angeles CA
and we are in Arizona. So by the time I could get the admins in this
Facility to figure out the problem and then reload windows after the krnl32
error. It was 12 hours, then I had to rebuild all the accounts and 50+
domains manually since I neglected my duty of backing up the registry. 2
more hours. Unfortunately all appearances to our customers was that we were
completely down when in all essence we were still receiving their email but
they could not send.
I suppose I am after a backup Send Gateway method for our users so that they
can feel comfortable by sending mail still and we can ensure them that their
incoming mail will be received promptly.
