Do local administrators on a system with SQL Server 2005 installed have an implied 'sysad

Gurus,
Is it true that local administrators on a system with SQL Server 2005
installed have an implied 'sysadmin' right to SQL Server?

1 first, be sure you give some windows account (yours maybe) sysadmin
rights on sql server!!!
2 then, check 1 again!!!
3 then, remove BUILTIN\administrators login from logins on SQL server|||Unless the OS is Vista+SQL Server2005 SP2 (may be also WinServer2008+SQL
Server2005SP2).

It just so happens that I had to figure out how to disable this myself
just last week. I worked on SQL 2000, but hopefully this will work on
2005 as well.
I put this into a .sql file and called it using osql, in this way I
was able to scipt this change and execute it on our hundreds of
different servers very quickly.
However, you could just drop this into query analyzer (built into EM
in 2005 I recall) and run it:
exec sp_denylogin [BUILTIN\administrators]
That is it, that will deby local admin access to MSSQL. I also
scripted the changing of the sa password if you need that it is:
exec sp_Password 'OriginalPasswordHere', 'New_passwordHere1', 'sa'
Hope that helps!|||On Mar 13, 9:13=A0am, Tonagon <tony.robe...@.marriott.com> wrote:

OH! Something to look out for though. If you deny login access to the
Windows Admin group then the SQL Agent service will stop running and
say it cannot connect. By default it will be connecting using a local
Windows Admin account. That will have to be changed (you can right
click it in EM and go to properties and change it).
I found a script for that as well, but it is rather long and I don't
even understand the whole thing. It works though! If you need that as
well I can put it in here.|||<<OH! Something to look out for though. If you deny login access to the

Agent do not run under an Admin account by default. It will run using the account you specify in
setup, and can also change later on using SAQL Server Configuration Manager. The handling of service
account is done the same way and tools for SQL Server service as SQL Server Agent service.

Thanks for the clarification Tibor! I thought it was by default
simply because I see it that way on all our systems, but since they
were all installed the same way that only means it is by default for
me, not for the actual software. I guess he wasn't concerned about
that though since there was no response.
Then againk, I am more then a little slow to check things myself.|||<< Thanks for the clarification Tibor! I thought it was by default

that is what I thought. The main reason I replied was just to not leave this thread hanging with a
statement what can be read as the product being "not as secure" by default. :-)

themselves up as sysadmin.
%servername%\SQLServer2005SQLAgentUser$%servername%$MSSQLSERVER
%servername%\SQLServer2005MSSQLUser$%servername%$MSSQLSERVER
It seems that the default setup puts the service account into the later. All
anyone with enough power would have to do is drop an account into one of
these and presto! What are all of the implications of taking these roles out
of the picture (or at least out of admin)? Where is the best documentation
for fixing this?
