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.

Pinging dreambox [192.168.0.124] with 32 bytes of data:

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

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...
