You can use MS Clustering services to provide this level of fault
tolerance. The information store should sit on a shared disk array for
best results and performance. However, you can't get the performance
benefit of load balancing between servers with this method. As far as I
know, if you want load balancing, you just have to split mailboxes up
between two separate servers, at which point they cannot be clustered.

Subject: Exchange Information Store Replication

I'm looking to resist DoS attacks and provide a degree of fault
tolerance in Exchange. I basically want 2 Exchange servers doing the
job of one. Clients would not know the difference and be round-robin
distributed between the two servers. If one server went down, the other
would temporarily handle the full load.

Does anyone know of a way to run Exchange (any version) from a
replicated information store? Is there any kind of solution that would
allow this (short of a SAN)?

Please forgive me if this is easy... I am fairly experienced in
security/networking/programming, but Exchange is a new beast to me.

Thanks in advance!
