I have created a database that is housed on a server, and I am the administrator. I created user-level access for all of the users. When we began to use the database the users joined the workgroup and were able to login. Now everytime a user logs on from their own computer they get an error message "not a valid username or password". I have reset the passwords from my computer, and I am able to log onto their accounts from my computer, but they are still not able to log on from their own computers. Is this a server problem or is this a database problem??? HELP!
