Built in admin account Deleted

trying to comply with my companys security policy, I deleted the builtin\administrators account in sql 2005

Now I want to add an account so I can access the sql server but it will not let me. I am guessing that I should have added that account first, Any Ideas how I can fix this?

Do you have an 'sa' account and know the related password?
JonMnyAuthor Commented:
I do have the sa account. I think it has limited rights set up for windows authentication, also some other accounts were added and they have sysadmin rights

Scott PletcherSenior DBACommented:
Any account with "sysadmin" rights is good enough.  That will give you full authority once you get in.

Btw, I suggest not deleting the BUILTIN account but removing all authority from it.
