Dns problems with Vista - 26 Jun 2007 20:06 GMT

have a cisco 2800 router with 7 linksys accesspoints. As client i have
xp,vista and apple.

All xp clients works well they can surf in internet without any problems.
But vista and apple clients doesn't.

i check everything but have till now not any solution. For exempla Vista pc
got all information from the router. i checked ip adress and dns adresses
well. if i ping to the dns adresses no problem but if i ping to
www.google.com i did'nt get any answer. And if i ping direct ip adress from
google like ping 209.85.135.104 i got answer.

Same in the browser if put www.google.com no answer and if i put the
ipadress i can surf.

i put ipadress and dns manualy but does'nt help.

And with nslookup i can't see the dnsservername i can see only ip adress.

More significantly than getting a response to a ping is what address
the lookup for the ping resolved to--also whether in order to resolve
that name to an IP address it also had to discover the canonical name
for an alias, which www.google.com usually is. Notice that ping -n 1
can show you both, even if the ping itself fails:

<cmd_output>
Non-authoritative answer:
Name: www.l.google.com
Addresses: 64.233.167.104, 64.233.167.99, 64.233.167.147
Aliases: www.google.com

F:\>ping -n 1 www.google.com

Pinging www.l.google.com [64.233.167.147] with 32 bytes of data:
</cmd_output>

> And if i ping direct ip adress from

Where did you get that address? FWIW reverse lookup here shows:

<nslookup>
Name: mu-in-f104.google.com
Address: 209.85.135.104
</nslookup>

It may help if you explained exactly what you did in case
there are errors in your procedure.

Guessing that you're seeing a local address for that?
E.g. via ipconfig /all

What happens if you log on to your router and find the real DNS addresses
being used? Then use either one of them as second operands for nslookup?
In fact, I think that getting those real addresses is what you would have had
to do anyway to "put ipadress and dns manualy". So then if you had done
that correctly ipconfig /all would have been showing them there too.
Otherwise I don't think that there is a requirement to have a reverse lookup
for dns server names.

If you're having trouble with your real DNS addresses it may help
to use nslookup in its interactive mode with set debug as the first
command.

BTW This is slightly off-topic for the IE NG and I don't use Vista.
You may get more knowledgeable assistance from Vista Networking.
E.g. another possible unique factor with it will be whether IPv6 is involved.
Cross-posting for convenience.

Good luck
