I believe our DNS server needs to be "refreshed". If I set DNS server to be internet service provider's DNS server, I can resolve names to IP addresses. However, our primary and secondary DNS server is down (does not resolve names to ip addresses). Is there any command which would do it (maybe download fresh information from the service provider's DNS server). We are not able to to receive mail as a result of that... we also cannot surf the net if we set DNS server address to our DNS server's ip addresses. Thanks.
