Hey Claude, here’s good news: what has happened to you is not at all uncommon, 
and there is a solution. It’s just not at all obvious. 

While you’re right that the backup and restore has created the “same” database 
with the “same” users on the new machine, the fact is that to SQL Server, they 
are not “the same” users. There’s an essence of the identity which is NOT 
equal, even though the usernames and passwords are the same, and that’s why CF 
(or anything, really) can’t login using the “same credentials”

So what you can do is run a script (a system storedproc) that fixes that, 
called sp_change_users_login. It has a few variations. All you need is one 
form. Here’s a simple walkthru of using it:

http://dbadiaries.com/using-sp_change_users_login-to-fix-sql-server-orphaned-users

This has a nice visual layout but doesn’t really focus on the “why” you need to 
do this (the issue I discuss above). For that, you could see this explanation:

http://tim-stanley.com/post/how-to-restore-a-sql-user-after-a-sql-database-restore/
 

Or see this MS document, which also explains it and then offers this 
sp_Change_users_login as one of a few alternative solutions you could consider 
for this situation:

But let’s see what else Andrew may have had to offer as well.

What option are you referring to ?? I am able to re do the backup from the 
other server again so what options do i need to select to ensure when I restore 
on the new sever the new servers credentials are applied to the database I have 
restored from the old server
