This DST patch specific to Exchange will only matter if you are using
OWA in your environment. If you are using all Outlook clients on
desktops, make sure you rollout the DST patch for the OS on those
clients, as well as the server. Outlook clients use the OS time zone for
calendar and other items, whereas OWA does it differently using CDO. If
you don't have the Exchange 2000 DST patch OWA will show incorrect times
during the 3-4 week period, i.e OWA will assume the old DST standards.

Subject: [ExchangeList] Exchange 2000 and DST

I am being asked by the powers that be at my company what the worst
possible scenario is if we keep our Exchange 2000 server running past
March 11, 2007 without spending the 4 grand for the hot fix.
While an Exchange 2003 or 2007 upgrade is in our near future, we doubt
it will happen before this date.
At this point, it looks to me like the time stamps on email, calendar
entries, etc will be off by an hour for approx 3-4 weeks until the first
Sunday in April (old DST date) rolls around.  After that point is it
safe to assume email and other Exchange objects would have the correct
time stamp?
My main fear, is the fear of not knowing what to expect.  Can someone
shed some light or speculate what could happen?
