Hi,

Have a look on both server and workstation what's in /etc/resolv.conf

This will list what DNS servers are being used. I suspect the server uses your providers DNs and your workstation uses the one running on your server... which does not seem to be running.

Best of luck.

thanks for the quick reply

im using windows machines on lan
and the contents of /etc/resolv.conf are

search viewhosting.com
nameserver 127.0.0.1
nameserver 208.67.222.222
nameserver 192.168.3.1

OK,

Try this.

On Your Linux server, type:

host www.google.com 127.0.0.1
host www.google.com 208.67.222.222
host www.google.com 192.168.3.1

See which replies?

On windows do the same in a 'shell' (CMD)

nslookup www.google.com <Linux server IP>
nslookup www.google.com 208.67.222.222
nslookup www.google.com 192.168.3.1

Report back your findings :)

Hi,

So the only DNS that works for you is 208.67.222.222

On your Linux server, change your resolv.conf to:
search viewhosting.com
nameserver 208.67.222.222

On windows, edit your DNS settings to include the above IP.

You can check what you currently have by typing ipconfig /all

Let me know if this helps.

go to /etc/nsswitch.conf

in
hosts "files dns"
change to "dns files"

Argh, so sorry. Can't read. Problem was with LAN not WAN.

All the same, you have DNS entries that didn't work so nothing's lost but still... sorry.

thanks it worked

i just changed the dns on windows machines

thanks a lot once again
