DNS not resolving - email forward fails

[pluk]

Suddenly when I do a ping or traceroute, it no longer capable. What can I check to see the problem? Right now, all emails forward don't work because the server says there is a name resolving issue.

Can you help?

First you should check if the nameserver ip is responding, do a ping on the nameservers ip addresses.

Then check if named is running, either in DA or SSH (service named status).

If that fails go to dnsstuff.com and check that the nameservers for your domain is correct, and what ip address the show.

This is what the admin did...

# cat /etc/resolv.conf
nameserver 65.125.236.42


which appers to be a dead nameserver.
Added 127.0.0.1 to the top of the file to use your own NS.

And now it does work. The problem was no resolve from the server to out.
