My /etc/resolv.conf file looks like this:

search my.corp.domain.com
nameserver ip1
nameserver ip2
nameserver ip3

I compared the IPs and the domain name with what was get from one of my
Windows PC, they are the same. So, I think it should work.

On thing I forgot to tell you last time, is that, I am in a domain which
is controlled by a ISA server. I am not sure if accessing the DNS server
needs authentication also...
