Problems with appending DNS suffix for name resolution

Hello,

we have a strange problem with DNS name resolution in Vista.

For example, suggest our company's DNS-root is 'ourcompany.net'. If I try to
ping a host in a subdomain of 'ourcompany.net', for example in
'site2.ourcompany.net', Vista does not append the suffix as expected -
although I have configured it correctly under network configuration.

IPconfig shows the following:

H:\>ipconfig /all

Windows-IP-Konfiguration

Hostname . . . . . . . . . . . . : nbecovista02
Primäres DNS-Suffix . . . . . . . : site1.ourcompany.net
Knotentyp . . . . . . . . . . . . : Hybrid
IP-Routing aktiviert . . . . . . : Nein
WINS-Proxy aktiviert . . . . . . : Nein
DNS-Suffixsuchliste . . . . . . . : site1.ourcompany.net
ourcompany.net

If I ping the FQDN 'host1.site2.ourcompany.net', everything is fine. If I
ping only 'host1.site2', no IP-Adress is returned. But what the above shown
IP-Configuration is concerned, Vista should append 'ourcompany.net' by its
own.

If I ping a host, that is placed in the same domain 'site1.ourcompany.net'
as the Vista client, directly without any suffix it is successful.

It is improbable that we have a problem with DNS, because our XP-Clients
work perfectly with this IP-configuration.

I hope, anyone has an idea what's going on there.

Are you using a beta version of Vista? I had this problem with the beta
versions but it is fixed for me in the RTM version.
 
Hi Kerry,

thanx for your reply.

Unfortunatly, I'm using the RTM releases of Vista Ultimate and Business.
 
What results do you get for nslookup host1.site2 ?

Do you have WINS running throughout the network?
 
Curiously a nslookup for host1.site2 works! ;-O It was a good idea I have not
tested before.

But now the most interesting question is: why does a nslookup work and why a
ping or mstsc-connection does not???

Although we have WINS running, the WINS servers in our sites do not
replicate with our central site. So name resolution via WINS is not an option.

Have you anymore ideas?

It is starting to sound like a NETBIOS problem but I'm not sure what. What
was the full results of nslookup?
 
Hi,

the output looks like the following. As I have no English language pack
installed, the output is German. I hope you can guess what the output shows:

C:\Windows\system32>nslookup host1.site2
Server: dnsserver.site1.ourcompany.net
Address: 10.2.70.160:53

Nicht-autorisierende Antwort:
Name: host1.site2.ourcompany.net
Address: 10.73.32.51

A ping to the same adress looks like:

C:\Windows\system32>ping host1.site2
Ping-Anforderung konnte Host "host1.site2" nicht finden. Überprüfen Sie den
Namen, und versuchen Sie es erneut.

The German text means that the host could not be found and I should check
the name. I guess, you know that message... ;-)

By the way: I have disabled Netbios over TCP/IP.

I'm lookinbg forward to hear from you again.
 
What happens if you

ping -a 10.73.32.51

I think this problem is probably beyond my skills. You may want to try one
of the server networking newsgroups. There are some very knowledgeable
people there.
 
Hi,

the ping command you suggested works fine: the FQDN of the host is returned.

I have posted this thread now in the Windows Servers DNS group now.

Anyhow many thanks for your efforts. ;-)
