removing system administrators from fixed server r

Hello all, On Analysis Services 2005 the members of the Administrators local group are also members of the fixed server role, therefore they have full control over Analysis Services databases. I think this can be a problem becouse many system administrators don’t need full control over AS. Does someone kwon how can I remove those high privileges to the local administrator? Thank you. Hernan.

When you are logged in as an Administrator in Windows and connect to SQL Server, you account maps to BUILTINAdministrator which has sysadmin privilege in SQL Server. You could grant another group specifically for SSAS access by using GRANT <ALL or required privileges> TO DOMAINSSASGroup You can also add that user a role which has the privileges you want, for instance to the sysadmin role.

thank you.
but how can I do that in Analysis Services?
First verify if doing this will not have a negative impact, there are certain services that will require you to take additional steps. http://support.microsoft.com/kb/317746/en-us If this does not apply then you can either remove the built in account from management studio or take its sysadmin permissions away.
thank you.
but how can I do that in Analysis Services?
Analysis Services 2005 uses only one Server Role which local admins are automatically members of, in SSAS under properties/security the local admins are hidden therefore cannot be removed. If someone knows differently I would like to know how.
In Management Studio right click on the server, select properties, turn on the "Show Advanced (All) Properties" option and scroll down to the bottom and set the "SecurityBuiltInAdminsAreServerAdmins" property to false.
