I am using the newest version of ubuntu
the network is ok, I can google, I can facebook.
But when I try to check my company webmail (internal), it said cannot resolve hostname
what is happening? My window vista is doing ok with the webmail.
The webmail is microsoft online web access.
Ipv6 is disabled.
Using DHCP for ip address setting and DNS server configuration
I go through the internet with a proxy
and without using that proxy, I go not internet totally.
Can anyone know what is happening? Thank you.
