Need a sysadmin login

We’re running mixed mode authentication on our SQL Servers.To make the server “safer” builtin\admininstrators no longer have sysadmin role on the sql server.If there is only one login with sysadmin role, and we lose track of the password, is there any way to recover it?How could we reset the password or create a new sa account with a new password?This situation has not occurred, but I’m worried about how to recover from it should it occur.This question relates to SQL 2000 and SQL 2005.

David Zokaites,

If you deleted the users and have no available sysadmin user you will be locked out of your server for the sysadmin work. Therefore I always suggest to create a user which is not used and only available for these scenarios. Depending on the kind of security level the password can be stored somewhere in a safe or at a secure place.

Jens,

Thanks for the information. I thought the scenario might lock me out of sysadmin on the sql server. I will certainly make sure we have a secondary sysadmin account to prevent such a disaster.

Jens is right as far as SQL Server 2000 is concerned. For SQL Server 2000, you can get locked out; if that would happen, you can recover other databases than master by reattaching them on a different SQL Server instance.

However, in SQL Server 2005, by restarting the server in single-user mode, a local administrator can get access to SQL Server as a sysadmin, so you cannot get yourself locked out of the SQL Server instance.

Thanks

NDF and MDF data backup

Our server crashed. I was able to boot up in safe mode and copy the data
onto an external USB harddrive, all except our MDF file - i was able to
copy the 9 other NDF files and the LDF file. Our MDF file has very
little of our data, but i know it has SQL information in it.
What are my options on a restore? Can i create a new DB on the new HD
(which will create all NDF, LDF, and MDF), and then stop SQL, copy the
NDF and LDF from our USB drive, and then start up SQL again, and will
that work?
Remember, the files are just copied, not any kind of SQL backup.
TIA
Darin

and ndf files.
Are you sure you do not have a backup of your database anywhere in the
cabinets in your room, hmm?
You didn't mention what kind of a crash it is, however have you tried some
kind of File Recovery software to try to recover that mdf file?
I hope another friend of mine here has to say something to recover it...

doesn't have a drive on. I am getting a new HD to put in the original
server, where that HD crashed, just trying to get up and running now.
I do have a backup of older data (MDF, NDF, and LDF) on my machine and i
tried to do what i wanted and couldn't get it to work. After creating
the new database, and then coping over the old MDF, when i restarted
MSSQLSERVER, the enterprise manager showed the database, but there isn't
a + sign next to it, so there are tables, views, etc. strange.

If you have the mdf, ndf and ldf files, you can try to do an "attach". More

/Sjang|||that is my problem, i don't have the MDF. I created a new DB and tried
to copy just the NDF and LDF and keep the new MDF and attach the DB and
it didn't work.
I have a new HD and will hopefully be able to restore from the tape
backup.

kinda toast.

It contains references
to all other database files.

>[/vbcol]|||In a message of yours you have MDF file of your database and in another you
say you do not have it.
Creating a database from scratch and copying your other databases NDF and
LDF files and using the new database's MDF file would not work. It doesn't
work like that. You need the MDF file of your original database. If not,
then you have to use your backup to restore your database.
