Can Management Studio Express manage SQL 2000?

Can I use SQL Server 2005 Management Studio Express to manage existing SQL Server 2000 instances?

Yes, it can. I've suggested that people set this up when the non-Express version wasn't available and it works beautifully. Well, almost. The only thing I know you need to look out for is generated SQL scripts. Sometimes they aren't compatible with SQL Server 2000. That's the only thing I've run into, tho.

Hope this helps!
