Forcing Domain Logons in Win98

[Nicholas Humfrey]

Sorry this may be a bit off topic, but I thought someone here might have
manged this:  I am trying to force people to logon to my classroom domain
before they can access the computer. However I cannot prevent people from
typing an invalid domain name, which passes the logon over to 'Windows
Logon' giving them access to the system. Is there a way of infocing a
single domain or preventing logon to invalid domains ?

Thanks
