Help! Removing SQLServer builtin/Administrators

Hi,
I'm having trouble maintaining security on SQLServer as
everyone who is a member of the Local Administrators (on
the system) has full control by default as SQLServer has
builtin/Administrators added by default to its System
Administrators List.
Last time I removed this group, so many things went
wrong. I dont' want the entire local administrators to be
the SQL Admins. So please suggest a way where I can
safely remove the default Built-in\Adminstrators from the
SQLServer security. Any article will be helpful.
ThanksIf you subscribe to SQL Server Professional, I wrote a piece on this:

Briefly, you can add a domain account to the sysadmin role first and then
remove the BUILTIN\Administrators role.

Thanks|||Adding to Tom's suggestion, you could also add a domain local group (with
only members you wish to have sysadmin equivalence) and grant that group
sysadmin permission -- then remove the builtin\administrators group. It's
also not a bad idea to reset the 'sa' account password at the same time in
case you need that account to log back in (in mixed mode).
