Dear The Expert,
I did not find attach menu in Ms. SQL Server 7 ...? I have tried to use query analizer .. by running the following commands:

EXEC sp_attach_db @dbname = N'ABC 2.3e Professional',
@filename1 = N'D:\Project\Abc\Communicator 2.3e Prof\Data\abc-db.mdf',
@filename2 = N'D:\Project\Abc\Communicator 2.3e Prof\Data\ABC 2.3e Professional_log.ldf'

and I got error message .. "Invalid header file with the ldf file"

please help, many thanks in advance

Best Regards
Winan
