Installed a new DNS...

Old DNS-reverse Lookup Zone is called 1.168.192.in-addr.arpa on Windows 2000
The new one that I created is called 192.168.1.x Subnet

Is this something new on Windows 2003 server or have I done something wrong?

Hi,

For reverse lookup to work, the IP address is always reversed.

e.g. if your network is 192.168.1.0 , the zone must be 1.168.192.in-addr.arpa

Please see:

During the installation of DNS I choosed to config a reversed zone...
I added my net and got the reversed name and choosed it....
But it still shows "192.168.1.x Subnet" under Reverse Lookup Zones in DNSMGMT

Hi,

Do not look to the name, see the zone file or zone info. The link provided earlier shows how it should look like.

Under Forward Lookup Zones I got one object "my domain"
Under Reverse Lookup Zones I got "192.168.1.x Subnet

Where should I be able to see the above info?

Hi,

I have the same thing on my dns server. I do not know where MS DNS store zone info and if it can be viewed.

Any, way you may download dig tool (http://members.shaw.ca/nicholas.fong/dig)

and use it to see zone info. Just run

dig 1.168.192.in-addr.arpa

and it will list for you the zone info from your server

Any way you can configure some prt records under that zone and use nslookup to verify it.

Hi,

Do you face problem in doing reverse lookup for your ips on this server?

If you face problems, then try to remove it and recreate it.

I do not know why the file was not found in your case.

I tested in internet explorer to connect to a site with the IP adress ...

If I test with nslookup:

> nslookup 192.168.1.10
Server:  [192.168.1.10]
Address:  192.168.1.10

*** 192.168.1.10 can't find nslookup: Non-existent domain
> nslookup 192.168.1.1
Server:  [192.168.1.1]
Address:  192.168.1.1

*** 192.168.1.1 can't find nslookup: No response from server
> nslookup 192.168.1.7
Server:  [192.168.1.7]
Address:  192.168.1.7

*** 192.168.1.7 can't find nslookup: Non-existent domain

Hi,

your testing with ie is to access a website with an ip address rather FQDN. Accessing with IP address does not require dns server since you already got it.

By the way, are you able to access the internet while pointing to your dns server?

Internet is working for both servers and clients...  
The problem is the Exhangeserver, does not want to start, trying to connect to the old DNS-server...

What to add in reverse lookup zone?

Hi,

Why the exchange server is trying to connect to old dns server? Configure the server to point to the new dns server ip (from the nic tcp/ip properties).

The Exchange (192.168.1.7)  nic is already set to use DNS 192.168.1.10 as primary and 192.168.1.7 as secondary..

Both ipconfig /flushdns and restart have been done..

Hi,

I looked at the attached pics and I can tell you that it is the same as I have it on my w2k3 server. It seams that MS has changed how the zone name is shown, but to the dns system it is still 1.168.192.in-addr.arpa domain.

You should be able to find the file in the \windows\system32\dns dir

Hi,

This means that the dns server 192.168.1.10 does not know any thing about the reverse lookup zone.

ok, try

nslookup
> server=srv07.domain.local
> 192.168.1.10

here the other dns should give you the information

By the way, from where you got the info you posted earlier?

Which server is the primary for the reverse lookup zone?

Do you have zone sync between the dns servers?

Yes, sync works between srv07 and srv10. If I delete something in DNS on srv07 its also deleted on srv10..

How do you mean with
nslookup
> server=srv07.domain.local
> 192.168.1.10

what do you want me to write in nslookup and on what server?

The 192.168.1.10 should be primary DNS server. Is there anywhere I can tell this?

Same result on both 192.168.10 and 7

On the srv07 - Exchange server

Server:  srv10.domain.se
Address:  192.168.1.10

*** srv10.domain.se can't find nslookup: Non-existent domain

Does not understand how I should do this, please explain..
"then set the dns server to query
server  srv07.domain.local   (no equal sign)

Ok,

when you configure dns in the nic tcp/ip properties, you entered ip address of certain dns server(s) to use for dns queries.
when you install dns server on a m/c it becomes the dns server to query for dns resolutions.

now when you run nslookup tool, it uses the default (as explained above). Now to query a different dns server you run nslookup with no arguments. then you tell nslookup to use different dns server (like the one given). then you give your query and wait for results.

Thats what I wanted to see if other dns servers are able to reverse lookup ips.
