Once again I am shamed by the knowledge on this BBS. That explains one of the unnamed IP addresses in the DHCP client log. I'm starting to understand how it works now. I set up the bridge quite a while ago using a different PC so I've got no idea of the username/password. I'll have to try to use the installation CD to see if it will show me at least the username.

You wouldn't believe I make a living out of IT.
