Hi there,

How can I add a RDNS for my IP?

This is what I'm trying to prevent:

C:\>nslookup 212.199.133.100
DNS request timed out.
timeout was 2 seconds.
*** Can't find server name for address 10.0.0.2: Timed out
Server: pdns.myisp.net
Address: 212.199.129.3

*** pdns.myisp.net can't find 212.199.133.100: Non-existent domain

Do you have an Active Directory domain?
If you do, you should not use your ISP's DNS in your NIC setup.

This:> *** Can't find server name for address 10.0.0.2: Timed out
is cused because nslookup performs a reverse lookup on the IP it is
pointing to. You can configure a reverse lookup zone for 10.in-addr.arpa set
it to allow updates to the zone restart the netlogon service it should
complete the zone with sub folders and the PTR record.

Just to add, that error:
*** pdns.myisp.net can't find 212.199.133.100: Non-existent domain

Well, when I ran it:
==============================
C:\>nslookup 212.199.133.100
Server: ponyexpress.bandwidthpros.com
Address: 208.47.39.10

Name: 212.199.133.100.forward.012.net.il
Address: 212.199.133.100
==============================
I got the response above. My feeling is that forwarders are not setup or a
firewall block.

I tried all of that. I refreshed, re-created, restarted, still nothing.

and btw I can't restart the netlogon service because I'm not in domain :-(

Any workaround?

There isn't such a thing as a "workaround" for this, but rather the way your
clients are configured and the way the zone (if it exists) is configured.

Jason, to create a reverse PTR, create a reverse zone that matches your IP
subnet. Then rt-click on the zone, create a new PTR (pointer), then tell it
the IP address, then tell it the full FQDN. If not sure how to create a
reverse zone, here's a helpful link:

308201 - HOW TO Create a New Zone on a DNS Server in Windows 2000 [Forward
zones, CNAMES, Host Records, MX Records, Name Server Records and Reverse
Zones]:
http://support.microsoft.com/default.aspx?scid=kb;en-us;308201

So in your case, when creating a reverse zone for your subnet, 10.x.x.x,
rt-click reverse Lookup Zones, new zone, in the wizard, just type in 10,
then next next next finish. Then go into it's properties and set updates to
YES. That's pretty much it.

Normally if you are using and pointing to your DNS server, this is automatic
when using W2k or newer machines. Just make sure in your zone properties
that updates are allowed (set it to YES). You should also set your Forward
Lookup zone to Yes also.

Well, not sure if you already did, since you didn't state it, but make sure
your machines (including the DNS server) are only pointing to your own DNS
server in their IP properties. This way when it registers, it will register
to it. If any other machine is in your properties, it will try to register
elsewhere and you won't get proper registration.

If using DHCP, it will by default register the clients for it.

Also to add Jason, set a Forwarder in your DNS server for efficient Internet
name resolution.

http://support.microsoft.com/?id=300202 will show you how to in Step 3.

Thank you Ace!
It all worked out great with your suggestions.

I was indeed pointing to external DNS servers on the network card
properties.
The second I updated it with my records, it worked flawlesly (and
automatically).

Thanks alot!
