DNS Host Records Missing

Hi,
We are having an issue where DNS Host records seem to be missing, a user logs on and they don't get their group policies. They can logon again and get their group policies. However the DNS Host record is still not created on the DNS Servers.
If we reboot the PC the DNS record is created. What is going on.
We have 2 DC's running DNS, and one of them runs DHCP.

Hi,
According to your description, my understanding is that client does not registry record in DNS server when user logon. And the DNS record will be created after rebooting the client.
DNS updates can be sent for any of the following reasons or events:
1. An IP address is added, removed, or modified in the TCP/IP properties configuration for any one of the installed network connections.
2. An IP address lease changes or renews with the DHCP server any one of the installed network connections. For example, when the computer is started or if the
ipconfig /renew command is used.
3. The ipconfig /registerdns command is used to manually force a refresh of the client name registration in DNS.
4. At startup time, when the computer is turned on.
5. A member server is promoted to a domain controller.
A user logon behavior will not trigger DNS update/registry. You may Open CMD on client and type
ipconfig /registerdns command to manually force a refresh of the client name registration in DNS.
If I have any misunderstanding about your question, please correct.

DHCP Reservation Sync and DNS Host record sync etc shown in IPAM GUI

Hello all,
I am aware of the scripts in the TechNet script center to sync DHCP leases etc to IPAM, however my question is about something else -
If you highlight an IP address (IP address inventory->select an IP), You can see fields that say: "DHCP reservation sync", "DNS PTR record sync" and "DNS host record sync" as below:
I was curious as to what these are for. Is there some built-in sync functionality for these that I perhaps have not enabled? (Don't see such options any where..)
thanks,
-Ravi

Hi Ravi ,
The three columns tell us the information of the synchronization between IPAM server and DNS server (or DHCP server) .
Here is the detailed guide for using IPAM :
Using the IPAM Client Console :
https://technet.microsoft.com/en-us/library/jj878351.aspx#inventory
IPAM can sync DNS and DHCP records .
The IPAM database is separate from DHCP and DNS servers on our network ,and full synchronization of hosts and IP addresses between IPAM and managed DNS or DHCP servers does not occur automatically
unless we have configured automated tasks to perform this synchronization .
For detailed information ,see
DNS and DHCP record synchronization chapter in the following link :
Multi-server Management :

DNS host record

We recently successfully decommissioned a child domain. However, we have found a non-domain system which was referenced in the child domain DNS as a host record - xyz.child.root.com
Where can I add this host record in the root.com domain, so it can resolve to services contacting that name? The child domain no longer exists.
Thanks.

Hi,
What does a non-domain system record mean?
This host record seems
for a computer located in child domain. If this record is for a computer located in child domain, this record will not efficient.
To add a host record to root domain, you can create a new host record in the root domain and input the corresponding IP and record name for the new record.
Besides, after you decommissioned the child domain, you can run dcdiag /test:DNS to check the health of DNS.

OT: DNS Host record with an @ symbol

I have switched to the DNS hosted by my domain registrar
(Network
Solutions), and I am curious if these default "A" records are
necessary to
keep:
@ (None).domainname.org
* (All Others) .domainnamename.org
They are currently pointed to the same IP address as
domainname.org.

DNS host records priority

Hi,
We are using EPM (Enterprise Project Management) in our organization.
We have to provide access to it from three different subnets:
Local
Organization1
Organization2
The DNS already added the host record for the local IP. Ex.: srvepm 192.168.0.1
Then we added two other host records for the other subnets.
Ex.: srvepm 192.168.10.1
and
srvepm 192.168.20.1
We have an alias to that server: epm (that is related to the srvepm server)
It works fine. But, some machines in our organization keeps getting the other IP addresses from the DNS and this is making the service unavailable for those machines.
What I did is unchecking the "Register this connection's addresses under networking settings.
But when the server was rebooted the three host records were erased and it keeps shuffling it to the machines.
Anyone knows a way to fix this problem or how can I set priority on host records so it doesn't makes that anymore?
Hope I was able to show my problem correctly.

Since the app is not AD aware, it's using Netmask prioritization. Here's more on it below - and sorry for all the links. It's a heavy topic with lots of factors governing it. If the app was AD aware, then we would create AD Sites, and let AD handle it.

DNS (srv record missing for PDC)

Hi,
in our company we have a domain with 4 domain controller (all are Windows Server 2008 with domain functional level 2003).
In the DNS, under _msdcs.OURDOMAIN.priv -> _tcp there are only the SRV _ldap record related to 3 domain controller; there isn't the record related to domain controller that holds the PDC role.
From some months we have also issues about GPOs replicas between domain controller.
It makes sense to create the missing record ? There may be a valid reason because it is not present ?
Thank you.

Hi,
Did the PDC host the DNS role at the same time? If yes, please make sure that you have enabled secure dynamic updates on the DNS server. You can stop and restart
DNS server by running the command below at the command prompt:
net stop dns
net start dns
On the PDC, please stop and then restart the Netlogon service by running the commands below to see if the SRV record is created in the DNS server:
Net stop netlogon
Net start netlogon
If the above solution is not helpful, please try to
manually enter the SRV records from Netlogon.dns file in \Windows\System32\Config or create on the DNS console.
Best regards,
Susie

Bulk Import Static DNS Host Records?

I have a text file with the hostnames and IP addresses for a large group of new computers that should have a static host entries.
How can I import these into Server 2008 DNS without having to type them in one by one?

Hello,
You can achieve this using Powershell 3.0 if you have Windows Server 2012. Or you can install Powershell 3.0 on your Windows Server 2008 and perform the task. More information on:

Can DNSServer Powershell module cmdlets be used to add a host record with a blank name? i.e. "(same as parent folder)"

Giving Add-DnsServerResourceRecordA a blank name yields an error (basically saying that the 'Name' parameter cannot be null or empty). In DNS Manager (dnsmgmt.msc)
adding such a host record yields a record with the same name as the parent folder, denoted by "(same as parent folder)" in the Name column.
Is there some flag I can pass to Add-DnsServerResourceRecordA to achieve the latter functionality? Is there some other way to achieve this in Powershell?
I currently have the line of PS below, and if $name="" I get the error.
Add-DnsServerResourceRecordA -IPv4Address $ip -ZoneName $zone -Name $name -ComputerName $dns

Thanks, Calin!
This could be added as an example here: http://technet.microsoft.com/en-us/library/jj649925.aspx
Now that I see your answer Example 6 looks like it was supposed to use -Name "." but part of the line is missing so it just looks broken instead.

We are having an issue with one domain bellsouth.net we are basically getting this back from them.

When I looked up the Detected error on SMTP command, I found some information about the Hostname, currently on our server it is setup as Hostname/DNS "A Record" name: ndhc.org (according to the internet domain holder (godaddy) the host name is ndhc.org and the "A" record name is mail. What should we have in the Hostname/DNS "A Record" name field? I believe that we have tried the servername.domain name (liberxx.ndhc.org) and that failed and I think that we also tried (mail.ndhc.org) I cannot confirm that we actually have it has been awhile since we did this project, but I am just wondering if someone can help clear this up for me. Thank you. This issue only started happen with Bellsouth.net when we switched from the NetWare GWIA to the Linux GWIA is there something else that might have been missed.

mail.ndhc.org
Okay, so you think we should try putting "mail.ndhc.org" into that section (Hostname/DNS "A Record" name field) instead of what we currently have "ndhc.org"
But that error doesn't sound like it's related to DNS. It much more
sounds like you're really blacklisted for sending spam. If it's really
the hostname, then their system is giving out extremely stupid result
messages. Have you tried to contact the given email address in the
message?
I know when we first setup the system we were having an issue with the GWIA relaying, but that has since been rectified, they are the only ones that are blacklisting us, because I have checked on other sites (blacklisting websites that is) and there is nothing about our site being blacklisted. I think basically the people that are trying to receive the messages respond back saying that they never received emails from the people here at ndhc. If memory serves they have been emailed from other accounts and those go through because Bellsouth.net is not blocking those accounts, like yahoo, gmail, etc.

DNS Host name problem

Hi, I am a newbie to AS. Nice to join the family and meet u all.
I got some problem during installation of AS 2005Q2, when I install and select 'Config Now' option, I cannot pass since the DNS hostname always fail.
If I select 'Config Later', I will find something is missing, like asadmin tool is not avaiable.
Since I will use the Ip only, can I disable or bypass the DNS host name? since no matter how I enter it always fail.
Please advise, thank you very much in advance. :)

DNS "A" Record Preventing Networked Users from Seeing Own Website

I just set up a DNS "a" record in Server Admin to point "mail.xyz.com" to my server's internal ip (10.0.1.1).
I did this so users could stay on the network with sending and receiving mail, as opposing to going out onto the web to do so. (I have MX records on Network Solutions point "mail.xyz.com" to my server's external ip.) All of their mail clients list "mail.xyz.com" as the mail server, instead of the server's internal ip.
Trouble is, when users on the network try to access our website, "xyz.com," their browsers now return an error, saying they cannot find the server.
Any idea?
Lost count Mac OS X (10.4.9)

Steve and David --
This works. I am using Server Admin. To reiterate, I
added a zone "mysite.com" and a primary server "mail"
and pointed it at my server's internal ip so my users
can stay "inside" while checking mail.
Then, to follow your suggestion, I added a machine
named "www" to zone "mysite.com" pointed to my
server's external ip.
Some questions: How can I be sure the client's
machines are going interally to the server for mail?
(When I dig it in terminal, "mail.mysite.com" returns
an "a" record for the server's internal ip -- I
suppose that is sufficient.)
Yep!
Should the primary name server for the zone be "mail"
with "www" as an added machine, or vice versa?
The primary name server just identifies the machine which is responsible for holding records for that zone (domain). Add www as a 'machine' - think of each 'machine' as a specific IP address which identifies a host, hence IP / Name partnership. Any other hostname on same IP is an 'alias' (which becomes a CNAME record in the dns file).
You say I have to do this with "any record hosted in
my public dns as a mirror." I am running three
websites from my server, all with public dns pointed
at my server. (I use the same mail
server--mail.mysite.com--for all three.) Do I need to
set up a "www" record for each website? I have no
problem accessing the sites from internal client
machines.
the basic issue is that any zone (domain) defined in your own dns becomes 'authoritative' for that domain. So when clients ask your internal dns about any zone (domain) which is defined in it, and your server does not have that record, it will respond with "no such record" and your clients must take that on face value.
Therefore, you only need to mirror records for domains which you have defined in your own dns. If you have external www.domain1.com and www.domain2.com but only have domain1.com established on your internal dns, then you only need that domain's www record mirrored. Your server will therefore not be authoritative for domain2.com and will pass all requests out to whichever external dns is authoritative for it.

IPhone Restore + Pairing record missing.. HELP!!!

I restored my iPhone 4S and when it restarted, I got an error message stating "iTunes could not connect "iphone" because pairing record is missing"... I have restarted my computer numerous times and reinstalled my itunes twice. My iphone is now blank and won't connect... PLEASE HELP

I had the same problem (pairing record missing) and was finally able to fix it. My host computer is a Windows 7 64-bit setup. I kept reading where others solved the problem by eliminating the Lockdown folder, but I couldn't find that folder in Windows. But it was there in the following location: C:\ProgramData\Apple\Lockdown. After closing iTunes, I simply renamed the Lockdown folder to Lockdown.old and restarted iTunes. I then plugged in my iPhone USB connection and it worked. (Changing the folder name required Administrator privilige.)

@ host record

I am trying to point my root host record to my public ip address that is the same as my www hosted outside of my network. I can't put in @ in DNS to represent that. I know at one point when you created a zone it would automatically create that @ record but I had to remove mine because it went to the OS X server hosting the DNS. Can anyone point in the right direction for creating a @ host record on Mac OS X Server 10.5?
Thanks

Hi Dan,
Unfortunately I don't have an OES2 box in front of me. But I did find this documentation: Novell Doc: OES 2 SP3: Novell DNS/DHCP Administration Guide - Using iManager to Manage DNS
It should be sufficient to walk you through the creation of a resource record in iManager.
Let us know how it goes.
Cheers,

DNS Host pointing to an IP address of a host added to the domain

Hello
I have a server already joined to the domain, I need to migrate a file server, I want this file server host name to point to the actual server that is already joined to the domain. For some reason my company decided to create a host instead of using a DNS
Alias (CNAME),
Look like it is working fine, I can connect to the shares.
ServerA -> File server to migrate
ServerB -> Server to host the ServerA shares
But on some cases looks like authentication is failing for some applications,
Do you know if there is a Kerberos limitation? I am not sure if I should set a spn

Hi,
Could you share the error message with us?
I don’t think DNS CNAME record cause the problem as long as you have configured it properly.
In the meantime, you can do some troubleshoot the issue according to the articles.
