Basil - just an FYI ... several times in the last week I've tried to reach BCF and received a "text-ish" page saying something like "maximum users exceeded". I *think* it was from the SQL server? But it was around 6am EST and doesn't seem it would be reaching max users - unless other server services count as users.
Or maybe cookies are "doubling up" when a member remains logged in and returns several times during the day? creating "multiple cookies" making your server think there are more services and folks logged in than are really there?
I remember when I ran Novell servers, and operations like indexing and backup were considered as "users" by the system.
