AutoLogon

Here's my problem:

I'm trying to AutoLogon to a 98/ME image on my machine. I
can do this. I'm trying to then turn the AutoLogon off
automatically. I can do this too. Then I'm trying to turn
it back on automatically, and this seems to be the hard
part.

To turn it off, all I needed to do was change the value
of the HKLM\Network\Logon\PrimaryServiceProvider back
to "Microsoft Network". I can turn it back on again by
emptying that same key. The problem is this, the persons
who will be using this AutoLogon are on a different
domain then the AutoLogged on account. If I go back and
empty that key I can specify the user with the
HKLM\Network\Logon\username key, but I can't find a way
to specify the domain.

Does anyone know if there is a key in the registry that I
can manipulate to change the domain as well as the
username?

Any help would be appreciated,
Thanks

If anyone is curious, I have found it. The key is
HKLM\System\CurrentControlSet\Services\MSNP32
\NetworkProvider\AuthenticatingAgent.
