1) Try reversing the configurations.  If you use ex0 for net B, can you
now ping net B hosts?

2) Does 'ifconfig -a' show everything to be configured correctly?

3) Check the media settings (ifconfig -m ex0 displays the possible media
setting, I believe) - some may need to be manually tweaked depending on
what cards, and sometimes what switches (Ciscos, among others, can have
problems with autonegotiation).

Hope this helps,
