Heard back from my MVP buddies. The concern is re uninstall issues. Here
is what MVP Hilary Cotter had to say:

"That is correct. SQL Server 2005 replaces the SQL 2000 connect libraries
with the SNAC. The SNAC includes the SQL 2000 connect libraries (MDAC), but
the SQL 2000 connect libraries do not include the SNAC. If you install SQL
2000 after SQL 2005 it which whack the SNAC.

So order is important.

Refer to http://support.microsoft.com/?id=905618 for a work around.

Here is how I remember it SNAC=Yummy. MDAC=Not Yummy."

Hmm. That's news to me. I'll check in the private MVP group and get back.

I was just able to perfom this in our test environment (I didn't realize we
had a cluster set up this way so I could test).

It installed perfectly. Are there things I don't know about that might
happen?

We have an SQL Cluster active/passive, currently running SQL 2005 as a
named
instance.

We want to now install SQL 2000 as the default instance. Microsoft says,

"When you use SQL Server 2000 installations and SQL Server 2005
installations on the same cluster, the SQL Server 2000 installations must
be
installed before you install SQL Server 2005 instances locally or as
failover
cluster instances."

Does anyone know if this is a best practice or a requirement?

Thanks!
