Admin privilege

Does an mssql Admin account has the privilege of accessing or modifying the DB of another user account(not admin)?

I am asking that cause i am wondering if the admin @ a remote hosting location can modify the DB data.
Thanks

i think they do. but why would they want to do that?

It all depends on how your security is setup. By default, SQLSever comes with the 'sa' account setup as the root user. 'sa' has full access over all databases, but this is easily changed thru the "Security" setup - or thru 'users' under your DB.
