DNS migration

hi,
im doing dns migration from one set of servers to other set of servers.
dns takes about 24 hrs for TLDs(com. etc) zones and about 48 to 72 hrs for gTLDs(co.uk etc.). to avoid any kind of outage during this time - can I leave both servers as authoratative servers? will it avoid any kinda outage?

Hi,
If I understand your question accuratly then the answer is yes. As long as the cached records will resolve you should have no issue. Once expired you can safely decomission the original set of nameservers.

Domain Controller, DHCP, DNS Migration from 2008 r2 to 2012 Essentials

I would like to migrate Domain Controller, DHCP, and DNS functions to a new 2012 Essentials server in a 2008 r2 domain. I would like the 2008 r2 server to remain as applications server. Is it possible to do this? I've seen in TechNet
a reference to this type of migration, but am concerned about the reference that after 21 days the 2008 will shut down. Is it that the server will shut down or the Domain Controller function on the 2008 will shut down? I will need the 2008 setup as is
for our application server, so I want to be sure that the migration will not interfer with that.

As long as your existing server is not also an SBS or other Essentials server, it'll be fine. The shutdown after 21 days occurs when multiple SBS or Essentials servers are on the same domain.

UNIX DNS Migration to Windows AD DNS

Hello,
We are planning to Upgrade our AD before that our Root Domain DNS including _msdcs is on Solaris Bind.
We need to Migrate _msdcs, root DNS to Windows based AD integrated DNS. we have already added both Zones as secondary into Windows DNS where AD is configured. Now We need to make transferred _msdcs and root DNS zone as primary and Windows DNS
should transfer update to Solaris DNS
what changes/configuration we need to do before making those Zone as primary? do we need to change SOA or anything
Also, we have other zones in Solaris for those domain we are not using any Active directory. those domain zones also we added into Windows DNS, for those zone what changes/configuration required to make primary and transfer update to solaris DNS till
we remove all Solaris DNS IP from Servers side?
Here also do we need to change SOA or anything?
Is there any complete migration steps or video?
Regards,
Swapnil

Hi,
Maybe i am missinterpreting your post, but If you have an AD environment set you already had _msdcs zone as AD integrated, when you created the first domain controller assuming this is 2008 or later OS. Along with this zone you have the AD domain zone
which is as well AD integated. So i am not sure how you can get same zone as AD-integrated again since AD will complain the zones(s) already exist.
I have done migration from Linux bind to Windows but not for other directory service integrated zone and the process was like you mentioned by seconding teh zones in windows then make them primary and ad-integrated and secondary on linux.
I believe you will have to export or make an inventiory of the 2 zones and then create any missing / required records.
Maybe others have better suggestions.
Hope it helps.

DNS migrated- can see webpage on all computers except two iMacs w/different

The webhost for our website had a hardware failure a couple of days ago, and migrated to a different server. Within hours, I could see the website on my pc at work (Firefox) and my friend could see it on her pc w/IE. But at home, no matter how many times I reset Safari, or restarted my iMac (10.4.8), I got the error page from the webhost- for over 30 hours. It finally came up when I got up at 6:30 this morning, then another friend emailed me and said he couldn't get the website (at 11:00 a.m. this morning) using a four year old eMac with Internet Explorer- even after clearing the cache. Is this just a Mac thing?

It has nothing to do with your Mac, but your ISP's DNS servers.
All DNS servers will cache DNS data and serve requests from the cache. The zone file will include a tag that tells DNS servers how long to cache the data for.
What you're experiencing is most likely an effect of that cache. For example, if your DNS is set to cache for one day and user A performs an initial lookup via ISP A's DNS server at 11:59pm then all subsequent requests to the same DNS server will return the same result for the next 24 hours. Even if you change the zone file at 12:00am the ISP's DNS server believes it has a valid data and will return the same result until the 24 hour timeout has expired.
In the meantime if User B performs an initial lookup via ISP B's DNS server at 12:01am he'll get the new zone data with the new address.
This conflict (where two different servers claim to have valid responses that are different) is known as the DNS propogation delay and it's largely out of your control since it's affected by servers outside of your domain.
The only thing you can do is to lower the timeout for your zone so that remote servers cache the data for shorter periods of time, with the corresponding increase in traffic to your DNS servers since the ISP's DNS servers will make more frequent requests for your zone data, even if it hasn't changed.

DNS migration - final days to comply

Business Catalyst is in the final stages of completing the migration to Amazon Web Services. As part of this project, we are working on decommissioning the old datacenters and removing the DNS proxy put in place more than 7 months ago, at the beginning of May.
If you have not yet migrated your website until now you are now seeing a pop-up window in the front end of your website, prompting you to migrate update your DNS to the new settings.
Failure to conduct this change in the next 10 days will lead to your website becoming permanently unavailable.
Updating your DNS
Sites with DNS hosted on a 3rd party domain registrar (e.g. GoDaddy) must update their DNS records to point to one of the the new data center IP addresses. The legacy data center IP address will be decommissioned on June 20th, at which time if you have not updated your DNS records, your sites and hosted email will no longer function. Please update your 3rd party registrar info to our new IP addresses and create SPF records for each domain - you can use either of the two new IP addresses for your region when changing your DNS records:
           Europe                           54.246.209.120               or               54.246.209.119
           United States                           54.236.190.114               or               54.236.189.64
           Australia                           54.252.148.183               or               54.252.148.191
For detailed instructions please refer to this page on the official migration website.
If you have questions please do not hesitate to reach out for help with this final task in the migration.

Thank you Magda, is there many left to do?
Anything Partners can do to help you get the message out?
Should look to try have things like sandpile mention this to partners etc?

Lion DNS Server not answering reverse IP queries

I just upgraded my server to 10.7 lion. Everything works great, except that the DNS sever will not answer queries about reverse IPs. Interestingly OD isn't affected yet though as I add more replicas I'm afraid that problems might start cropping up.
Queries for forward zones work fine. Reverse zones don't
I tried restoring from backup without luck.
I found a directory called "/etc/dns.migrated-2011-08-06-002722" with the standard "loggingOptions.conf.apple", "options.conf.apple" and publicView.conf.apple.
I checked another server that was also upgraded to Lion, the DNS service is running (it only has the original DNS name of the server when it was set up) and it shows the same symptoms; forward zone works, reverse doesn't.
Has anyone seen this? Any tips for "fixing" my 200+ IP addr zones?

I've got this problem, too. I've tried a few things that have not worked.
1. importing a plist from another working (SL) DNS server. The zones all get imported, including reverse; however, the reverse zones are missing their nameservers. After I fill in all ~50 rev zone NS entries (it validates to make sure they are all filled in), it looses all of its data. All that time I spent is wasted.
I've tried this on my backup server with a fresh lion/admintools install and again after software update
2. I've deleted /etc/named.conf and /etc/dns/db.* and placed a fresh named.conf in /etc
added one reverse zone, setting its NS. same thing.
i was much happier with snow leopard, which is what i ordered from cdw, but they delivered these

Relocation error : /usr/lib/libresolv.so.2

I am facing this error message whenever I launch mailx program. The error is as following : "/usr/lib/libresolv.so.2: symbol __nsl_fopen: referenced symbol not found".
What do this error indicates? Does it require patches? Thanks in advance for all help.

Hi mate,
I also have received the same error after adding a patch (to solve the DNS cache poisoning) using the -u "unconditional" option :

Replace Windows 2003 DC with Windows 2012 R2 Foundation

Hi
We are a small office (7 users) that currently have one Windows 2003 Server configured as a domain controller running DNS,DHCP and file services for users. All computers (7) are joined into local domain. All users have mapped drives to 2003 server shares
and redirected (offline) folders for my-documents configured.
Due to an old hardware, we decided to buy a new server with Windows 2012 R2 FOUNDATION licence. For our company I thing this will be the best choice, since Foundation has CAL's 'included' in license, and for our requirements will be more than enough.
Foundation server limit is that server must be the root domain controller in a domain that has no trusts at the root of the forest. My question is how can we 'replace' old server with a new one (what are the steps) ? I'm thinking the following scenario:
- install server and promote it to a DC with a new local domain name in the new forest
- copy all data from old server the the new one
- put all computers out of old domain and put them back into the new domain that is running on 2012 foundation.
- power off old server
Most of the work will be with computers, that need to be reconfigured to a new domain ?
Is this the right approach, are there any other (better) options ?
Just thinking... Is it possible to join 2012 Foundation into existing domain, than transfer all roles from old server to the new one, and at the end demote old server and power it off (I know this is standard approach in Windows Server Standard editions
Thank you in advance
Mike

Hi,
There is no necessary to create a new domain. we can add the new DC to your current domain, then transfer FSMO, related settings and main service roles to the new DC.
Reference the link provided by Alceryes to add Windows Server 2012 R2 to your current domain. and then reference link below for
Active Directory Migration from Windows Server 2003 to Windows Server 2012 R2：
http://blogs.technet.com/b/canitpro/archive/2014/04/02/step-by-step-active-directory-migration-from-windows-server-2003-to-windows-server-2012.aspx
Besides, for DHCP migration from 2003 to 2012, you can reference：
http://blogs.technet.com/b/canitpro/archive/2013/04/29/step-by-step-migration-of-dhcp-from-windows-server-2003-to-windows-server-2012.aspx
For DNS migration, install DNS server role on Windows Server 2012 R2, and configure it as secondary DNS servers to the old DNS servers. Do replication, once completed, change it from secondary to primary. Remove old server and also clear their record in
new DNS. Checklist: Migrate a DNS Server(also applied for WS 2012 R2), for your reference:
https://technet.microsoft.com/en-us/library/cc755303.aspx
It is better to do a test lab and backup related data before migration in your current environment.

Trouble authenticating after 10.3.9 - 10.4 upgrade?

I recently (reluctantly) upgraded my Xserve from Mac OS X Server 10.3.9 to 10.4, and I can't authenticate users that exist in the shared directory domain. The server has been an Open Directory Master for some time now.
Within the Workgroup Manager application, I can see the Local directory, and all system users including Admin uid 501. I can also select my old shared domain under /LDAPv3/192.168.11.10 (server's local IP address) but I can't see any users or authenticate using the Admin login. I can, however, select /LDAPv3/127.0.0.1 and see all of my old users. I presume I can also make changes using the Admin login but I haven't tried.
Stranger still, I don't see anything in the logs that would indicate a login failure for normal users. Successful Admin logins appear in the Password Service Server log.
I have a feeling that these authentication issues are related to DNS. After upgrading, no zone files appear in the Zones tab of the DNS editor within Server Admin, even though the Overview tab shows 3 zones allocated. Aside from that, DNS appears to be running, all my zone files are still in /var/named and /etc/named.conf appears untouched. Logs indicate that named starts up correctly and I can do DNS lookups without any problems. For whatever it's worth, I tried using the command-line DNS migrator script.
I'd been using the Open Directory Master configuration to authenticate local clients for remote home directories, etc. but I'm not anymore. I really only need user authentication for mail, FTP and file sharing services - would it be more appropriate to do a clean install and set it up in a Standalone configuration instead of trying to fix it? If not, does anyone know what might be going on here?
Thanks

Hi, Duane. Trash the new, empty iPhoto Library folder that was created when you exercised the "Create Library" option. Open iPhoto, opt to "Find Library", and navigate to your original iPhoto Library folder. Select that folder, not any of the files or folders inside it. That's your library.
The standard, default path to that library folder is: Your hard drive>Users>your account name>Pictures>iPhoto Library. You can move the library elsewhere if you like, but if you have no good reason to do so, leaving it in the default location is probably best.
A cardinal rule for iPhoto users is never to tamper with any of the things inside an iPhoto Library folder. Everything inside that folder is arranged exactly the way iPhoto needs it to be arranged, and next time you open iPhoto, it expects to find all the contents exactly as it left them last time. If you tinker with the contents of that folder via the Finder, or using any tool or utility other than iPhoto itself, the library database will be corrupted for iPhoto's purposes, and some or all of your pictures or albums will seem to have vanished the next time you open iPhoto.
There is a Discussions forum entirely devoted to iPhoto 4 and earlier. If you have further questions related to your version of iPhoto, I recommend posting them in that forum.

Migration of DNS from Windows 2008 R2 to Windows 2012

Hello,
We have a pair of Windows 2008 R2 servers running authoritative DNS services (they are not AD controllers, neither used as resolvers). There are ~20 domains + 10 DNSSEC domains hosted on those servers. We're considering to migrate them to Windows 2012
servers and retain IP addresses.
I'd greatly appreciate if somebody could advise the basic steps for such migration (particularly the DNSSEC part).
Many thanks.

Hi,
It worked for me with a test zone but my example only had a single A record. You should test this first by adding the zone and testing resolution on the 2012 server before deleting it from the 2003 server.
The bug for secondary zones that you describe in Server 2008 is news to me. However, 2012 and 2012 R2 has many advantages over 2008 R2 for DNSSEC signed zones so I would recommend you migrate even if you weren't having problems on 2008 R2.
If you've been following the thread you mentioned above, you know that I've been doing a lot of testing with signed zones being updated on secondary servers. The signed zone is *always* updated on a secondary server but if the change on the primary was only
a signature refresh then as of right now there is still a bug where the newest RRSIGs are not transferred to the secondary server. This happens because the zone transfer occurs just before the new RRSIG is generated on the primary. This causes it to be left
behind on the primary server unless there is another zone transfer afterward. Note that a zone transfer still happens, it just happens too soon. The zone transfer that happens is an incremental zone transfer.
If the previous RRSIG expires before another zone transfer occurs then the zone can have validation problems on the secondary. There is a hotfix for this that will be distributed soon. I am checking now on the date.
If you increment the serial # on the primary, the secondary should get a full zone transfer.

DNS EventID 4015 on PDC since Domain Migration from 2003 R2 = 2012

Hi,
following problem here:
2 Domain Controllers with AD Integrated DNS Zone, migrated from 2003 R2 to 2012. One Single Root Forest.
The Primary Domain Controller shows every 2, 3 or 4 hours the DNS EventID 4015. No further error is available: (which is may emty) "".
Only on the Details pane you can find this Information:

======================================
The Migration was made by the following steps:
Bring Up the first 2012 MigrationDC as 3rd DC to the Domain.
Move the FSMO Roles to the 2012 MigrationDC
DHCP Data migrated with Server Migration Tools, IAS Data with iasmigrader.exe exported
DCPromo DC1 (2003 R2) and Format C:
Install a fresh 2012 Installation on old DC1 an rename it again with the original Name DC1
DHCP Data migrated with Server Migration Tools, IAS Data with iasmigrader.exe exported
DCPromo DC2 (2003 R2) and Format C:
Install a fresh 2012 Installation on old DC2 an rename it again with the original Name DC2
Move Back the FSMO Roles to DC1
DCPromo the first 2012 MigrationDC
Metadata Cleanup for MigrationDC
DCDIAG /V /C Shows no Errors, all works good, the funny Thing is, that only DC1 Shows the DNS EventId 4015 in production evironment. The only exception is, that if you reboot DC1 (i.e. for maintenance, upates etc) than the error appears on DC2. Exactly on
that time, if DC1 is temporarily not availble and DC2 is under "load". If DC1 is back again, the Event 4015 Ends on DC2 and Comes back to DC1!!!
I backupped and restored DC1 and DC2 in an lab Environment, the funny Thing is that the EventID 4015 doesnt appear in lab Environment. The difference between prod and lab is: prod is bare metal with 2 teamed nics, lab is hyper-v vm's with 2 virtual teamed
nics. same IP's etc... DNS NIC Settings are the same.
It Looks like you can only produce the error in the production lab if you have the DC under "load".
This Event was discussed here more than one time in the Forum, but the issues doesnt match 100% to my Problem. No RODC is available in my prod Environment, the EventID 4015 has no further Errors "" in the Eventlog like in other Posts.
Ace Fekays blog :" Using ADSI Edit to resolve conflicting or duplicate AD Integrated Zones" was helpful for metadata cleanup, but it could not fix the EventId 4015 away. Because we had no Problems with disappearing zones...
Maybe Enabling NTDS Verbose Logging in the registry is helpful, but i dont know for what i have to Keep an eye out?
The thread
http://social.technet.microsoft.com/Forums/windowsserver/en-US/c0d3adb4-67d2-470c-97fc-a0a364b1f854/dns-server-error-event-id-4015-after-replacing-domain-controller-with-another-using-same-name?forum=winserverDS seems to match to my Problem, but also no
soulution available...
Any ideas what causes this "ugly" Event without noticable consequences?

Migrating servers DNS MX records

I am currently about to migrate an old Exchange 2003 email server to our new mac mini snow leopard server. I already have everything worked out and tested for migrating the email but I am having conflicting ideas on the DNS records. The challange is that I do not know when the old server will be physically turned off.
The way that I have moved mail servers before is setup the new mail server to accept email by updating the mx records, replacing the old server and then after a full population (eg 24 hours) I would remove the old server without any messages being bounced back.
My thought would be to use priority in the mx records to already have the new server at a lower priority so that if mail was sent and the old server was removed it would automatically start going to the new server.
Would this work in real life?
Thanks in advanced

My thought would be to use priority in the mx records to already have the new server at a lower priority so that if mail was sent and the old server was removed it would automatically start going to the new server.
That's precisely why MX priority records exist, and a perfectly valid use case. It also gives you a clear cutof - all mail will go to the old server until you shut it down (or take it off the network).
Another option, depending on your network configuration, is to change your network edge (assuming you're using some kind of NAT/port forwarding at your network edge - just change your port forwarding to forward to the new server.
A third option is to turn off the old server and configure the new server with the same IP address, so no-one's the wiser. This may be preferred if you have many clients configured to send mail through this server and aren't using port forwarding.
As you can see, there are several options here. All of them valid. Which one is 'best' for you depends upon our situation.

Need clarification on DNS, Certificate and URL? during 2010 to 2013 migration

Hi Guys,
I am working on a migration project Lync server 2010 to 2013.
Lync 2010 Standard Edition and Edge
Lync 2013 Ent edition and Edge (Enterprise Voice "SIP Trunk")
I need few clarification on How to setup the DNS, Certificate and URL Pre and post migration?
Shall we use the Lync 2010 existing internal and external URLs to lync 2013 or do we need to setup a new URLs for lync 2013?
How about the DNS records and Certificates?
I have gone trough the below blogs but need clear understanding on this part..
http://lyncdude.com/2013/08/11/understanding-lync-dns-records-and-autoconfiguration/
https://technet.microsoft.com/en-us/library/hh690044.aspx
and few more....
Thanks,

Hi,
Agree with Thamara.Wijesinghe.
You need to different Web service URL for Lync Server 2010 and Lync Server 2013. If you only have Web service URL for Lync Server 2010, then Lync 2013 mobile will fail to connect to FE Server. If you point Web service URL point to Lync Server 2013 Pool,
then both Lync 2010 and 2013 mobile clients will connect to FE Server successfully.

MIgrating DNS zone

Hi,
Sorry if this is a really silly question, I just need some clarification. I'm carrying out a project to migrate users/groups and everything else 'AD' from 1 forest into a target forest. There's a 2 way trust in place and I will be starting ADMT migration
next week.
My question is:
Obviously the source domain/forest has a DNS (AD intergrated) zone for 'domain1.com'.
In the target domain, we currently have a DNS forward set up for anything with 'servername.domain1.com' to forward requests to 'domain1.com' DNS servers.
As part of the migration process, I would like to export the zone containing all DNS records from 'domain1.com' to my target domain, and then switch off the forwarder, so the source domain's DNS is no longer needed.
What is the best way of doing this?
Thanks
Sarah

There should be no problem as long as there are not two servers up and running with the same configuration (When you migrate the DHCP, make sure that the old server is switched off after switching) and the DNS configuration is correct.

Migrating dns from windows 2003 to windows 2008 on workgroup env

Hi, We are planning to migrate primary dns server from win 2003 to win 2008. Both the old and new servers will be in work group. I have found few articles on how to proceed.
1. Configure new dns server 2008 R2 box as a secondary zone and doing a zone transfer for froward & reverse lookups from the primary Server 2003 machine. Then changing the name and IP of the Server 2008 R2 machine to
what the Server 2003 box was (after pulling the Server 2003 box off the network) as well as setting the 2008 R2 box as the primary. Neither of the servers will be connected to a domain at any point during or after this process.
2. Copy registry keys and dns files from old to new server
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DNS Server\Zones
Right click on the “Zones” node and choose “Export“. Save the export as a .reg file (e.g. DNS.reg).
Copy the DNS.reg file to the destination server and “Merge“.
Copy the DNS files
Copy the contents of the %SystemRoot%\System32\DNS folder from the source machine to the same folder on the destination machine. I received an permissions error while trying to transfer the “Samples” folder. It is not necessary to transfer the samples.
Set the DNS Load method
Using the Administrative Tools -> DNS MMC snap-in, on the “Advanced” tab, set the “Load zone data on startup:” to “From registry“. This tells the DNS server to load all zone data from the registry.
Then change the ip address and hostname of the new server to match that of the old ones and start dns service.
I was wondering which method would be easy and hassle free as I have like 23 zones to transfer.
Any help would be appreciated.
Thanks,
Lakshmi Soma

I would go with the first method as I always try to avoid making registry changes which might result in strange behaviors.
