There are a couple of ways around this, the problem with the most obvious is that apparently the Windows Bridging code dosn't correctly impliment STP.

I'm the network admin, most of my users wouldn't know what ssh is and shouldn't be trying to download anything in the first place. The basic problem is that trying to fit nearly 100 laptops into an IP network with a netmask of 255.255.255.128 isn't going to work if they require 2 IP addresses each. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFEtBaKsoRLMhsZpFcRAq7pAJ0Z9oNUzerujv5UXBU2RFPdkqwxJQCglGZb XI+UgwDWAlIxuQRUQn5YoLg= =x56G -----END PGP SIGNATURE----- -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
