Broken user creation

I have had an issue, because of a problem with MySQL dying, that I had a user created in Drupal, but not in the phpBB user table. I thought I fixed the problem by creating the user(s) by hand in the phpBB user table, but now when new users register through Drupal they do not show up in the phpBB users table. Their user names do show up in the config table as the 'latest user' but they have no account.

How do I fix this? Is there something like the sequences table in phpBB where I need to change the userID #?

Thanks,
Eric
