RE: [ActiveDir] DNS Question

Title: DNS Question

I was required to set this up on my external reverse look up zone since I was using a /26 subnet.  Of course these were not dynamic updates they were static.   I found this article from Microsoft http://support.microsoft.com/kb/q174419/ and it talks about how to create the zones.   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bernard, Aric Sent: Thursday, December 09, 2004 11:48 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] DNS Question   Unfortunately and to the best of my knowledge, Reverse Lookup zones have no affinity to a given subnet mask.  The zone name that you created will never be used by any client to register their IP address/name because as far as a reverse lookup zone name goes it is malformed – the subnet mask in any form should not appear in the name.  To test this statement, manually create a PTR record in the zone and try to query for by using a “ping –a” command.   Regards,   Aric Bernard   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Salandra, Justin A. Sent: Thursday, December 09, 2004 8:24 AM To: [EMAIL PROTECTED] Subject: [ActiveDir] DNS Question   I am trying to create a DNS Reverse Look up zone for a subnet that has a /21 subnet mask.  Now how do I create just one zone?  I created the zone 8/21.203.10.in-addr.arpa on the Windows 2003 DNS Server but my servers are getting an error when trying to register DNS PTR Records.  Event ID 11160 Event Type:     Information Event Source:   DnsApi Event Category: None Event ID:       11160 Date:           12/9/2004 Time:           11:03:25 AM User:           N/A Computer:       TCCHCCFP01 Description: The system failed to register pointer (PTR) resource records (RRs) for network adapter with settings:    Adapter Name : {2107EBC8-41E4-4FD0-B090-7AA39B224864}    Host Name : tcchccfp01    Adapter-specific Domain Suffix : tcchcc.chcsnet.org    DNS server list :         10.203.11.1, 10.203.11.2    Sent update to server : 192.175.48.1    IP Address : 10.203.11.3  The reason that the system could not register these RRs was because of a security related problem. The cause of this could be (a) your computer does not have permissions to register and update the specific DNS domain name set for this adapter, or (b) there might have been a problem negotiating valid credentials with the DNS server during the processing of the update request.  You can manually retry DNS registration of the network adapter and its settings by typing "ipconfig /registerdns" at the command prompt. If problems still persist, contact your DNS server or network systems administrator. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
