Coping Databases

Hi,

My questions is we want to make a copy of a database onto the same
server while preserving the diagrams, stored procs, etc.

We stopped the SQL service and made a copy of the data and log files.

We attempted to ATTACH the file copies (after re-naming them), but the
embedded file information tells SQL that the database already exists.

Our database is a piece of junk, but we must use it. If we don't want
to use the IMPORT/EXPORT Wizard to Copy Objects (because we get some
errors during the transfer), how can we make an exact copy of the
Database onto the same server while giving the "new" database a
different name?

Thanks
