Security bug on new SQL 2000 installation?

[toddman2k]

Just installed our first SQL 2000 server and I'm coming across a little problem.

I am trying to setup the SECURITY / AUTHENTICATION for the server to be "SQL Server and Windows" instead of the default "Windows Only"

When I make the change and click "OK", the change appears to work (no errors, etc). But when I open the Properties again, the selection is back on "Windows Only".

I've tried stopping and restarting the server to no avail. I am logged in as the administrator.

Has anyone else experienced this? Is this a "feature" that I'm unaware of? Is there some other security overriding my changes?

This is a brand new Windows 2000, SQL 2000 installation

Thanks,

Todd
