Correct invalid SID

I migrated my SQL 2000 secuity from one NT Domain to another. In the process of changing the login names in the master..sysxlogins table, the SID did not get updated.

Is there an easy way to correct the SID entry without dropping and recreating each user?

Do you mean that you have manually changed the login names in sysxlogins and you wish to update the SID entries as well? Can you explain what you meant by "the process of changing the login names in the master..sysxlogins table"?

Thanks

I ran the following in the master db:

UPDATE sysxlogins

Set [name] = 'NEWDOMAIN\' + substring([name], patindex('%\%', [name])+1, 200)

WHERE [name] like 'OLDDOMAIN\%'

It changed all the login names to point to the new domain. The problem was the SIDs changed (which I didn't think about) in the new domain. Users can get in, but when we try to use the function suser_sid(), the correct network sid is being returned and we cant compare it to the one in sysxlogins or sysusers because it doesn't match.

If you move from domain A to domain B, the Windows logins from domain A are normally invalidated. An exception to this would be if domain B was trusted by domain A, then you could still use the A logins even though the server runs in domain B.

This kind of domain change is not a supported operation. There is no supported solution for fixing this. It's not only the logins that you would need to fix, but all the database users as well. If you plan to change the domain for your server often, then you should use only SQL authentication.
