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.

DHCP server migration problem (2008 R2 to 2012 R2)

Hi,
I want to migrate my DHCP server from 2008 R2 to 2012 R2 server.I exported dhcp configuration by issuing export-dhcpserver command on 2012 R2 server.
And now, when I try to import xml into new server I see error during import:
VERBOSE: Importing option definitions on server...

Can you help me ?

Hi,
share out the Sysvol directory. However, it is recommended that you enable the system to share this directory.
For additional information about enabling the system to share this directory out on its own: (http://support.microsoft.com/kb/257338/EN-US/)
To verify that the Sysvol directory is shared out, you can either open Windows Explorer, or type
net share at a command prompt to see if the Sysvol share is showing. By default, the Sysvol share is located in the following folder: %SystemRoot%\Sysvol\Sysvol.
It is also recommended that you check the File Replication Service log. When replication has completed (with a domain with just one domain controller) the File Replication Service log reports the following event:
Event 13516: The File Replication Service has stopped preventing the computer from becoming a domain controller.
The system volume can take some time to initialize depending on the network.

Inter-site replication and KCC, when migrating from 2008 SP1 to 2012 R2

Hello,
We have a very simple AD infrastructure, two sites. I have built out a 2012 R2 server, extended the AD schema and promoted it to a domain controller. Reviewing the existing AD replication topology, we currently have a 2008 SP1 server as a DC
designated as the source/destination for inter-site replication, which appears to have been decided by KCC.
I will be decomming this 2008 SP1 server, having migrated off the FSMO roles to a few other DCs.
Will KCC automatically know to adjust the replication topology when the 2008 SP1 DC is offline? Should I demote it after migrating off the FSMO roles?
Thanks,
Matt

Hi,
Thanks for your post.
By default, the KCC reviews and makes modifications to the Active Directory replication topology every 15 minutes to ensure propagation of data, either directly or transitively, by creating and deleting connection objects as needed. The KCC recognizes
changes that occur in the environment and ensures that domain controllers are not orphaned in the replication topology.
For more detail information, you could refer to:
http://technet.microsoft.com/en-us/library/cc961781.aspx
For the migration, you could transfer the Flexible Single Master Operations (FSMO) Role and remove the Windows 2008 R2 domain controller, please refer to:

File Server Migration from 2008 Standard to 2012 Standard accross different subnet

Hi
Im going to migrate File server from Windows 2008 Standard server to Windows 2012 Standard . Source and Destination Servers are on different subnets . According to this
http://technet.microsoft.com/en-us/library/jj863566.aspx I cannot use Server migrations tool in-built into 2012 . Im not sure if I can use file server migration toolkit 1.2?.
Also my Domain controllers are mixture of Windows 2003, 2008 , 2008 R2 and I've upgraded the schema level to 2012 R2 . Is there anything else I need to be aware of ?
Can anyone please recommended best way to go about doing this migration . Is file server migration toolkit 1.2 is compatible ? .
Only reason I don't want to use Robocopy to this is because If I miss a small setting etc then I will face unwanted downtime.
I presume Migration toolkit will also create all the Quotas etc on the destination server .
Thanks
mumtaz

Hi mumtaz,
We could use file server migration toolkit 1.2 to migrate file server between the two subnets. In order to maintain security settings after the migration, please ensure the security of files and folders after they are migrated to a target file server, the File
Server Migration Wizard applies permissions that are the same as or more restrictive than they were on the source files and folders, depending on the option you select.
In the meantime, quota cannot migrate by this tool but we can export and import the quota using dirquota command. Export the templates as xml and then import to new server:
dirquota template export /file:C:\test.xml
dirquota template import /file:C:\test.xml

How to restrict users working on Windows 7 clients from accessing Windows Explorer and other systems in the network through Group Policy with a domain controller running on Windows Server 2008 r2

Dear All,
We are having an infrastructure setup of around 500 client computers managed through group policy.
Recently the domain controllers have been migrated from Windows Server 2003 to Server 2008 R2.
Since this account requires extremely strict environment, we need to figure the solution for restricting the users from access anything locally.
It would be great if you can assist me with the following query.
How to restrict users logged on Windows 7 clients from accessing Windows Explorer and browsing other systems in the network through Group Policy with a domain controller running on Windows Server 2008 r2 ?
Can we disable Network Tab on the left hand pane ?
explorer.exe is blocked already, but users are able to enter the Windows Explorer by clicking on the name which is visible on the Start Menu.

>   * explorer.exe is blocked already, but users are able to enter the

You cannot block explorer.exe when you do not replace the shell - the
desktop you see effectively IS explorer.exe...
Your requirement sounds like you need a custom shell:

I did an Unsupported InPlace OS Upgrade from 2008-R2 to 2012-R2

Well, I misunderstood what was supported and upgraded the OS on a SCCM 2012-R2 server from 2008-R2 to 2012-R2. (The one and only SCCM-server in the site)
All seems to work well, my concern now is what can I expect of future problems? Should I do the backup-install-restore procedure now to be sure or let it run until... "maybe something" happens?
Thanks.

"not supported" just means that MS did not test that scenario (and it does not automatically mean that it does not work).
I've done such an OS upgrade in my lab and were running into some smaller issues (MP/DP/SUP = the roles that require IIS) and were able to fix them by removing and re-adding those roles but YMMV.
The supported way would be: recover from backup. But you can also have a close look at all roles and see if they are still working.

Certificate errors after upgrade from 2008 r2 to 2012 r2

After upgrading a DC from 2008 R2 to 2012 R2, Outlook will no longer connect to outlook.office365.com. This appears to be a direct result of the upgrade, worked before and failed after.
I get a flurry of message boxes when I launch Outlook, and it will run but not connect. No path through the messages (granting permission to ignore the error, or installing the certificate) makes any difference. Not seeing anything in the event
logs, and have no idea how to fix this.
In addition, IE is now raising cert complaints on every site, doesn't matter which. Firefox seems to be managing okay, for the most part.
Thanks for any guidance.

Hi Michael,
I am so sorry for the delay.
I was trying to find more useful information about this issue, though there are very little information other than installing the trusted root certificate which is provided by the KB
article above.
I would suggest you download a
certificate chain and install it.
If this method still couldn’t help you solve this issue, since you are using third party certificate (VeriSign) for your organization, you can get more efficient support by contacting
third party support services.
More information for you:

Question about adding Windows 2012 R2 Domain Controller, into a native Windows 2008 R2 single forest domain

I current have a two server domain, both Windows 2008 R2 and fully updated. The two servers are on subnet 10.0.1.0 /24
- Windows 2008 R2 Server A: 10.0.1.1 (DC, GC, FSMO, DNS)
- Windows 2008 R2 Server B: 10.0.1.2 (DC, GC)
AD Domain: COMPANY.LOCAL
I have a second connected subnet, 192.168.1.0 /24) which is routed to the 10.0.1.0/24 subnet and I would like to install a Windows 2012 R2 server onto a server on that subnet and make it a domain controller with AD-Integrated DNS and DHCP for the 192.168.1.0
/24 subnet.
- Windows 2012 R2 Server C: 192.168.1.1
What are the proper progression steps, in order to bring up the Windows 2012 R2 server and then add it to my COMPANY.LOCAL domain and then promote it do a DC/GC/AD-Integrated DNS server? Are they anything like the following:
1. Install Windows 2012 R2 server (Server C)
2. Point Windows 2012 R2 server DNS servers at Server's A and B
3. Perform AD prep to extend AD schema to support Windows 2012 R2 domain controllers
4. Promote Windows 2012 R2 server to domain controller (install local DNS service on Server C, during this step)
* Question: Will Windows automatically create a DNS zone for the Windows 2012 R2 subnet (192.168.1.0/24) AND also include the DNS zone from the previous Windows 2008 R2 domain (10.0.1.0 /24)? Or will I need to add the 10.0.1.0 /24 zone to the DNS
server on Server C, even though the DNS from the Windows 2008 R2 domain is AD integrated?

Hi,
Regarding the issue here, please take a look into below articles:

http://social.technet.microsoft.com/wiki/contents/articles/12370.step-by-step-guide-for-setting-up-a-windows-server-2012-domain-controller.aspx
As the server is promoted to a DC, DNS Zones will be replicated and synchronized to it automatically whenever the new one is added to an AD DS domain, bascially there is no special need to add zones, for more information, please see:

Upgrading domain from 2008 R2 to 2012 R2

I am looking to upgrade my domain from server 2008 R2 to 2012 R2. We have 10 remote sites, each with a single physical ESXi host hosting 2 vms, 1 2008 R2 vm with the ADDS/DHCP/DNS/File Services (user home drives) roles and the second 2008 R2 vm
runs WDS/MDT and a couple applications. At our main site we have a physical 2008 R2 DC which holds all the FSMO roles, a vm with the ADDS/DHCP/DNS/File Services roles, and another vm running WDS/MDT.
I've gathered from my research that Microsoft recommends clean installs when upgrading DCs but since our DCs are also file servers that's not an ideal course of action for us, it'd be a lot of additional steps. My plan at this point
is to bring up a new physical 2012 R2 server, make it a DC, transfer the FSMO roles to it, then demote and retire the current physical 2008 R2 server. For the virtual DCs, since they are also file servers, I'm leaning towards in-place upgrades
on them, unless anyone would advise against.
The other thing I'm considering is creating a 2012 R2 DC at each remote site, then demoting the current 2008 R2 DC, leaving some combination of DHCP/File Services on it, then run an in-place on it to 2012 R2. This would requre another Windows license
though since our physical hosts are not on Hyper-v.
For the virtual servers running WDS/MDT, I personally prefer an in-place so I don't have to move the MDT deployment share, but I'm open to suggestions.
What are your recommendations? Which server should I upgrade first? How much time should I allow between each DC upgrade? I appreciate the help.

As per recommendations, A DC should be solely utilized for AD/DNS/GC & if environment is small for DHCP. The problem in using DC for other purpose arise during upgrade scenario, when you have to demote the DC or performance. Demoting the DC is very simple,
but if its running with additional role, it becomes challenging, if demotion has to be performed forcefully.
Secondly, from the security point, its not a great idea to run DC with other roles esp file servers, if there is any infected file then the whole domain can be compromised or infected.
What is more relevant in upgrade is testing the applications before you perform or upgrade the schema. If there is no issues then you can perform the upgrade based on your convenience. But necessary documentation & testing prior & post has to be
followed.
My personal recommendation would be upgrade the schema(surely test the schema upgrade in lab before you do in production), create a new server either VM or physical, configure it as an DC & transfer all FSMO role & slowly try to segregation between
DC & non DC servers.
Yes, i know it will cost additional licensing burden, but from the environment point of view it will provide you an ease of administration & troubleshooting.

How to test domain controller on upgraded Win Server 2008 R2

The windows team recently upgraded the development environment for the domain controller from 2003 to Windows 2008 R2 and I am to test the Idm functionality on this upgraded version. Our current configuration is that the DC and Idm gateway runs on different machines. To test this new DC, i want to install the idm gateway on that server and run some onboarding and termination test cases just to make sure if the AD connection is working on the upgraded DC. But i am getting ’Input/output error’ when i try to install the service and from the documentation it says 'The most common cause of this is that you do not have rights to work with this service.'. The server admin tried installing the gateway with his id as well and it failed. He tested installing in on the 2003 version of DC and it worked, so its not a matter of permission (i think..)...
Does anyone have any better idea on how to test an upgrade of a DC from version 2003 to 2008 R2? Any help in this matter is appreciated. We are running Idm 8.1 on a Windows platform and an upgrade to OW 8.1.1. Patch 2 is also in the works..
Thanks in advance.

I may have found a workaround. Can you try to change the "compatibility mode" in 2008 R2 to "Windows XP SP3" and see if it will install?
Admittedly I have not done this myself so I'm not entirely sure where or how it's done, but I have confirmation it resolves the issue from others who have faced it.

AD/DC/DNS From 2008 R2 to 2012

Hello
I have a Domain Controller (2008 R2), a secondary DC (2008 R2).
My new server is a Proliant Gen8 380p.
My new server I would like to put 2012 server on it ... it will be replacing the main domain controller (2008 R2).
It currently seconds as a DNS Server, File Server.
My concern is that if I add the 2012 server, that it may have issues converting 2008 R2 Accounts and settings to the new 2012 Server.
I am virtualizing this server. I installed 2008 R2 on it, but ran into issues with trying to use it as a file server. Hyper-v on 2008 R2 will only allow a 2TB volume; I have 5TB to use, which 2012 will allow me to allocate.
My vitural HD C: will be 400GB but my virtual D drive needs to be 5TB.
1. Will there be any issues with installing 2012 as my host machine, then 2008 R2 as the virutal machine, or should I have 2012 as my host and virtual?
2. If I put 2012 on my virtual instance, what considerations/issues will I have when windows tries to make it a DC in my domain?
Thank you

Hi,
If I understand your meaning correctly, you want to add a new Windows Server 2012 and make it a DC essentially,
here is an MS article talking about upgrade DCs to Windows Server 2012, see:
Upgrade Domain Controllers to Windows Server 2012
http://technet.microsoft.com/en-us/library/hh994618.aspx
And by now you have two DCs and a Windows server 2008 r2 with Hyper-v installed, right? Regarding the detailed information assiociated with Hyper-v, I think we'd better seek help in Hyper-v forum.
For the Virtual Machines and Guest Operating Systems, please see:

Hope this may help
Best regards

Migration from 2008 Foundation to 2012R2 Std

I have a client that needs to upgrade to Server 2012 R2 Std from Server 2008 Foundation. From what I gathered here on TechNet, the best way of doing this is to do the following in order:
1) Setup new 2008 R2 server
2) FSMO from 2008 foundation => the new 2008 R2 server.
3) Demote 2008 foundation server.
4) Upgrade the 2008 R2 server to 2012 R2 Std.
Is this correct or do I need to do any other additional steps?
(=Chris=)

Hi Chris,
Thanks for your question. However, I am not quite sure of your environment.
Is the Windows server 2008 Foundation a DC with FSMO role? Is it the unique DC in the domain? Since you mentioned “Setup new 2008 R2 server”, did you mean that you have another server except
the Foundation server? I would appreciate it if you can share more information about your existing environment.According
to the steps that you have provided, it seems that you want to migrate your AD from server 2008 Foundation to Server 2012 R2 instead of upgrading the operating system to Server 2012 R2 standard.
Windows server 2008 Foundation cannot upgrade to Windows server 2012 R2 directly, you need to upgrade it to Windows server 2008 R2 firstly. For general migration steps, you need to add the
new server into the domain and make it to be a DC and Global Catalog server. Then transfer the FSMO role to the new server. After you make sure that the duplication between the DCs is competeled, you can demote the old DC. In addition, I recommend you
to backup your old DC before migration.
Best regards,
Susie

Migrated database from 2008 R2 to 2012 getting wrong decimal precisions

Migrated SQL Server database from 2008R2 to 2012 using backup and restore option
When I do aggregate sum on both the databases 2008 and 2012 decimal precision is coming different. Because of this measure value in SSAS cube browser is calculated wrongly compared to 2008 R2 vs 2012
select SUM(rate) from [InfoDB]
2008 R2 Result
3029520.583895
2012 Result
3029520.58389499
Rate column is float data type Length 8, Precision 53, Scale is null
Please suggest if any work around for this.

Hello,
Does changing the underlying data to decimal possible? Instead of using float. Please try that.
Hope this helps.
