Again,  it's that question about layering, levels, and dependencies  which
you  choose for your system infrastructure. I sometimes have this  problem
where  one  machine  is relying on the uptime of another  or  the  network
in-between.  The  last thing you want is to include  Microsoft  technology
somewhere  in  the  middle  because, even if both ends  run  Linux,  their
connectivity  can be broken due to a Trojan, or a virus (under Windows, of
course). Common examples: Linux box communicates with a Linux mail server,
but  needs to go through a Windows firewall, router, or whatever.  Another
is  a  sequential  script that involves operation of some  function  under

Before  the SAN over here was changed from Windows to Linux, I suffered on
an  almost weekly basis because the Windows server collapsed and make work
virtually impossible. Moreover, it needed a manual reboot ever Monday. How
much  IT  staff (box booters) did it consume? Probably hundreds of  hours.
How  much  of /my/ time, as its user, has this spend? Probably  dozens  of
hours, over the course of 1-2 years. I can recall leaving work hours early
just  because  the server was down permanently. I had to cancel  meetings.
Talk about TCO...

Ever since the Linux migration a couple of months ago, not even a quirk. I
can  never reclaim these dozens of lost hours, which are worth hundreds of
pounds (for me /alone/). Again, talk about TCO...

The Exchange server that we have in no exception by the way...
