Hi Rajesh,
Couple of things you can check from the Database server end..
1. Assuming its a SQL server, check if the authentication is windows auth or SQL Server login.
2. Check if the user you are trying to connect with has login access to server and to the database. It is possible that when you have restored the backup, the user is still associated with the database but has lost the login rights....In a reverse context, it is possible that the users for the DB have not been backed up, the user has login rights but no access to database.
3. Try to login into the databse (SQL Server interface/client may be) with the credentials you have provided in MII Data server.
