Recover a Database without credentials

Is there a way to recover a Database if I don't have the original login credentials?

The Domian server broke and after fixing it* I cannot connect to SQL anymore

I always get error 1069, Login failure.

I would like to recover the database and reset the login credentials

Thx,
Uriel

* Fixiing it = Re-install Win2K server and build Admin and User account with same names and passwords, but likely there are other accounts or provileges that I am missing.If you have lost SA and other SYSADMIN privileged account then no way to recover the database, just take full backup and after reinstalling SQL server restore it back.|||Thx

I was assuming the worse.

Taking charge of someone else system is always a good challenge.

But anyway I appreciate the response|||What if you were to build a new system that you have access to, and re-attach the DB files on the new server? Or, you could get a similar result by rebuilding the master DB, applying patches, and reattaching there. These are not things I would like to do to production servers, naturally, but I think they can be done. let me know if you find this works.

Recover a database from MDF and LDF

If my SQL instance is not operational anymore because I lost the login credentials, Can I re-install SQL and recover the database from the MDF and LDF files?How about SA Login details, if you know the password or any account with SYSADMIN privileges you can connect to the server.

Even to carry on detaching and attaching you should require SA or sysadmin login, without proper detaching of DB you cannot attach.

Refer to Books online for SP_ATTACH_DB & SP_DETACH_DB for more information.
