Windows XP name resolution question...

[Michaelk]

Hi everyone,

This is probably basic for all you network wizard

Why does windows need the dot to resolve the name when the domainname
is empty?
(following the first label in the FQDN)

Check this example below:

C:\>nslookup dreambox
Server: dns
Address: 192.168.0.1

Name: dreambox
Address: 192.168.0.124

C:\>ping dreambox
Ping request could not find host dreambox. Please check the name and
try again.

C:\>ping dreambox.

Ping statistics for 192.168.0.124:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 1ms, Maximum = 90ms, Average = 23ms

Client is DHCP
Node type = Hybrid
Both the "Primary Dns Suffix" and the "Connection-specific DNS Suffix"
are empty

My linux hosts do not have this problem...

I there a way to turn this (annoying) feature of? All hosts are on my
internal home network so I don't really need a domain name...

Any other hints or clues?

Thanks in advance

Michael

Are you sure that you haven't named it with the dot? Ping works on a
"bare" name (and doesn't work if I add the dot) on my small XP
network.

Yes, I'm sure. This is how it looks on my linux box ( se below)

Note that I don't have the name "dreambox" in my hosts file, It's
beeing
resolved by the DNS on my linksys router.
(running Dnsmasq: http://thekelleys.org.uk/dnsmasq/doc.html)

$ nslookup dreambox
Server: 192.168.0.1
Address: 192.168.0.1#53

Name: dreambox
Address: 192.168.0.124

$ ping -c 4 dreambox

4 packets transmitted, 4 received, 0% packet loss, time 3000ms
rtt min/avg/max/mdev = 1.932/1.988/2.049/0.062 ms

It's not a big problem but a bit annoying...because it affects all
other commands
i.e. telnet, ftp, ssh....

Could it be a quirk of your router? As noted, my all XP network,
hooked up to an old Netgear cable router, behaves as you (and I) would
expect. I don't think its an XP issue. I don't have anything in my
HOSTS files, either.

Could be...

But what strange to me is that windows resolves the name correctly
(nslookup dreambox) witout a dot but can't use it...
