I did see that Win98 returned my domain ID for anything other than null, which returned my local Windows login; NT seems to behave as per the documentation in the MSDN, but Win9x is not behaving as expected it seems.

Why local and non-existent connections are returning any value without an error doesn't make sense.

If you only log into your domain, your local name is the same as your Windows system login name. I have a separate domain and local userid set up on my system here, which is why I return two different IDs. The only indication from Win98 that I've got the local vs the domain ID is that the domain ID is all upper case (and is obviously the userid I logged into the domain with, as opposed to the station)
