Cannot ping or browse web

Hi All!

A few days ago our mail server lost connection with the outside world. It
still receives and sends email but cannot reach machines off our network and
IE cannot go to any web pages.

I can't even ping Yahoo.com either by name or IP from this machine. Although
we can ping it from any other machine on the network.

We have a SonicWALL router that we use as our firewall.

Any suggestions?

Thanks,
Joe

If I change the IP of the mail server it pings fine but when I set it back
to its original IP it doesn't work again. I don't see rules in the SonicWALL
that is blocking the IP.

Try to use tracert to find out where it stops. Also posting the result of
ipconfig /all and routing table may help.
