Re: Redundency for SBS 2003

Hi Eddie.

Mal is right that you can have a Win2K3 Server in an SBS Domain as a
member Server and Replica Domain Controller, ( Which will consume 1 SBS
Device CAL in authenticating to the SBServer ) and the SBS CALs will
cover all File and Print Access to that server. However, to get Exchange
redundancy you'd need an Exchange Cluster, which SBS doesn't support. -
All is not lost however, Software Assurance Allows you to have a Cold
Spare ( Clone Offline SBServer ) and as Exchange 2003 has the recovery
store. you can bring that Server Online in place of your Failed
SBServer, have the clients working, restore the Exchange data from
backup to the Recovery store, and merge the mailboxes in real time while
the users are online.

Failover support in SBS is a big topic, and solutions ( Raid Arrays,
Mirrors, Cold Servers ) differ depending upon the risk factor.

If you need a Real Time Failover System then SBS is not the product for
that. You need full versions of Windows Server, Exchange SQL etc and
create a cluster.
