I normally demonstrate Windows 2000 Remote Installations in my class that I teach and have not had a problem before now. The clients don't find the RIS server and the only thing that changed since the last time I did this is that a Catalyst 2950 switch is now being used to connect our workstations instead of an old hub we were using. I'm not a Cisco person so I don't know where to start looking. Is there any reason why this switch could be causing this problem. Thanks for any suggestions you can provide
