I am trying to import .mdb (Access database file) to SQL Server.
Adding the sys-admin privilege username and password also does not help and gives an error - not a valid account name or password.
The file was corrupted as the file was changed from .mdb to .txt and then again .mdb. A fresh copy of .mdb helped me to restore the database.
A thing to remember, do not save the database with a password, always save the database without passwords, it allows a smooth restore.
