I've done failover and failback on my Exchange 5.5 server without problems,
Double Take does give separate instructions specifically for Exchange, and I
performed this about 10 times on a pair of test servers before bringing it
live. There are some things you need to do that are not documented when
failing back, but I spotted them in the lab beforehand (without checking my
doc's - removing Wins entries and rebooting the target after failover comes
to mind). Exchange takes a minute or two to fail over on my Exchange
server, due to the need to start all the various services.
Just curious, did you call NSI for tech support or Sunbelt? I did not have
a need to call tech support, but I'd like to know what I'm up against if I
do.

There is no problem with the failover it is the failback that does not work
as designed. You will be pretty much on your own also the tech support is
not very good. If you work with the product for more then a couple of days
you will not more then the support dudes.
We are using it with IIS, SQL7 running on NT and it works great, fails over
within 30 seconds. WE don't have a large volume of ecommerce so that is fine
for us. The fail back is the only spot where we have to go in and remove the
failed over ip manually because it just won't work right. It has once or
twice but most often it does not work as advertised. We have messed with it
and messed with it and - well, it is just easier to manually remove the ip
etc...
Hope that helps,
side note - we are using co-standby server for another app and it works
outstanding and it is much easier to configure. I like them both each are
unique.

I'd like to know if you've ever had to failover to the other server and
how quickly and smoothly, if at all that went?
Also, did you look at any other products or solutions before deciding on
Double Take and, if so, why did you decide on Double Take?
I understand that my situation may differ but I'm looking at using a web
server (IIS) and SQL 7.0 on NT or 2000 as the operating system (depends
on when the decisions are made) and data will need to be replicated and
if the primary server goes down there should be as quick and smooth as
possible a transition to the "backup" machine. I've had personal
experience with NT Cluster server and, for this application, the
failover takes too long. We are hoping to minimize transaction loss as
much as possible.
