Mac Os X


I have a mac os x full patched and trying to connect into exchange 2003 server, with windows 2003 VPN (routing and remote access/pptp). The Mac laptop connects in fine but can not ping any hosts and entourage does not work as well. I have 5 other pcs on the network all connect in and now routing problems meaning can ping all subnet fine.

is there anything I am missing on the mac config, I am not a mac expert by any means so I may be missing something simple.
