• 2 replicated domain controllers or clone 1 DCs as cold standby

  Hi guys,.

  I don't know if this is the right forum to ask this question or maybe someone can divert my question. Any involvement of a Windows 2008 Server cold waiting without any network connection for a period of time, tombstone question? and the reason that I asked for, it is I think to perform replication from domain controllers 2 where 1 fail and 2nd DC to support, or just to clone standby and connect the network whenever the 1 domain controller fail.

  Appreciate any comment.

  This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

• Remove 1 of the 3 domain controllers in a Windows environment

  I have a Windows domain that has Windows 2003 and 2008 R2 servers to support workstations, SharePoint and exchange among other things. There are 3 domain controllers. The first domain controller created on window 2003 server. Later, more 2 domain controllers were added on Windows 2008 R2. During the promotion of each of the servers in DC, each of them were activated as DNS and Global catalog servers. In addition, both 2008 DHCP configuration on them were servers and one Server 2008 R2 is configured as primary and the second as the secondary. The 2003 is just a DC member. I made main hold all 5 FSMO roles and replication works as well on both servers.
  I now have to demote the first Windows Server 2003, and then it must be taken out of the area. But whenever I have to run DCPromo to demote the server he kept a message that no other DC cannot be contacted, and when I try to disable the NIC in Server 2003, replication will stop automatically on the two 2008 R2.

  Any help please.
  Thanks in advance.

• Help with the Powershell script to collect logs from all domain controllers

  I am writing a script to retrieve the last 5 days of application, security and log files from all domain controllers. The script runs, but fire the logs from the local server only. The variable $Computer has all of my DC so it's the fine mark. I guess it's a problem with my line ForEach-Object, but is not error. See the below script.

  $log = 'application '.
  $date = get-date-format MM-DD-YYYY

  Hello

  I have three domain controllers in the network with a domain controller in each site. A DC with all FSMO roles. My question is if one of the other domain two among the site with no material of FSMO roles fail and it may be the power on. Can I build an another domain controller and forget the one who is crushed or is there a special treatment that I must follow?

• Commissioning for lack of Exchange because of the latency in Multi Site domain controllers

  Hi all

  I use using the OIM 11 g R2 PS2 BP04 with AD-connector version (11.1.1.6.0 & AD 2010) and the Version of the Exchange Connector (11.1.1.6.0 & Exchange 2010) and its installed on RHEL 6.5. We have 20:00 domain controllers and each of them is in a different site. Here is the list of domain controllers:

  DC-host1,DC-HOST2,DC-site2-host1,DC-SITE3-host1,DC-SITE4-host1...etc

  We use automatic configuration AD access strategies and resources the user Exchange and configured as domain controllers in AD IT resource:

  DC-HOST1 - primary

  DC-HOST2 - secondary

  AD resource provisioning works fine however when IOM tries to configure exchange to the user, its failure due to the latency issue b & w AD different Site of the domain controller. For example, "PRODTESTUSER12" is implemented successfully in AD and when IOM tries to configure exchange for this user, exchange server search for any available domain controller search for the user. It randomly selects an AD domain controller, I say DC-SITE2-HOST1 to search for the user. Since this domain contorller is on another site and it is latency, its not able to find the user of this domain controller, this is why available exchange fails for this user. See the below error:

  Target class = oracle.iam.connectors.icfcommon.prov.ICProvisioningManager

  < 21 may 2015 23:10:06 CEST > < error > < ORACLE. IAM. CONNECTORS. ICFCOMMON. Prov. ICPROVISIONINGMANAGER > < BEA-000000 > < oracle.iam.connectors.icfcommon.prov.ICProvisioningManager: createObject: error while creating user

  java.lang.RuntimeException: the operation could not be performed because the object 'PRODTESTUSER12' could not be found on 'anc-dc2k8 - 01.wssc.ad.root'.

  We have not specified this domain either under AD controller or Exchange resources.

  n Connector logs, I can see below: 22/05/2015-10:55:19 < INFORMATION >: class-> Org.IdentityConnectors.Exchange.RemoteRunspaceInstance-> InvokeScript method, Message-> enter the method

  
  22/05/2015-10:55:19 < VERBOSE >: class-> Org.IdentityConnectors.Exchange.RemoteRunspaceInstance,-> InvokeScript method, Message-> Script: Set-ADServerSettings - ViewEntireForest: $true; Get-User "PRODTESTUSER21" - ReadFromDomainController

  I think, because of this script, Exchange Server recovers first of any domain controller available to search for the user. Yes, is there a way to restrict or put domain controller's favorite?

  

  There is a hotfix available for this problem. Here are the details:

• Questions about the movement of 1 of 3 ESXi4.1-ESXi5 host domain controllers.

  Is this environment that I have 3 2008 R2 domain controllers.

  1 physical

  2 virtual

  I want to turn off a virtual domain controller and move first host (ESXi 4.1) on second host (ESXi 5).

  My concern is that if the NETWORK card in the guest OS is going to get dirty with or it will remain as it is.

  If I remember not the mac address will indeed change (unless I hard coded it in the configuration file), but that shouldn't be a problem.

  I don't know, what if a new NETWORK card will appear in OS making old useless NIC originally invited me to change the network settings.  Something I don't want to have to do.  I know I've seen a similar problem with a VM linux before, but don't remember seen happen in a virtual Windows machine.  Just want to be sure before that I have to try.

  Thanks in advance for your comments.

  
  Greg

  VM migration between hosts will make any changes to the NIC or MAC address. You must ensure that the required networking is presented with two hosts if you want to move between them seamlessly. If the network tag is not the same between the hosts, then you will need to change the settings of the virtual machine and use the drop down to select the appropriate network before turning on the new host. But this should be easy and quick and without surprise.

  See you soon,.

• How to disable snapshots for domain controllers in ESXi 5? Or other best practices?

  Dear all,

  I need some aspects of assistance to the deactivation of snapshots for 2 VMS in my HA cluster running Active Directory to Windows 2008 R2.

  I read that best practices for virtual machines running that active Directory is never for them to snapshot.

  I'm worried about auto created by the systems periodically snapshots and the problem arises if a snapshot is to be reinstated by mistake.

  So, what are the best practices for virtual machines running as domain controllers? To deactivate the snapshot function or other recommended methods?

  Please kindly share. Thank you.

  VMware has no system automatically taking portraits.

  Snapshots exist either because you made them manually, an application backup created. In this case, talk with your backup vendor.

• vSphere Client "domain controllers in confidence."

  I have a box of ESXi 4.1 with 4, Server 2008 R2 on it.

  Recently, I joined my domain name of the host. It seems to work very well (domain authentication, DNS host name, etc.) except that in the client, under configuration - host authentication services, I have nothing listed in "trusted domain controllers. The "type of directory services" shows active lists directory and 'domain' my domain correctly name. I could not find a definitive as to why my domain controller is not listed there (?)

  TIA.

  The area would be better described in "areas approved." Here is my setup showing three areas of trust and the domain in which the server is a member.

• Problem of VCB backup domain controllers

  I still do research the issue, it may or may not be true, but I was wondering if anyone had a DC using VCB backup problem. iSCSI connected proxy server.

  fact twice and twice (different days) I could NOT connect on two domain controllers. Event Viewer filled with the error logs related to DNS, ATN, time and many others. Restarting solves the problem.

  Someone at - it experience what that be like this?

  I would always advise against him. AD is a sensitive application and you should recover a domain controller virtual in the same way as a physical domain controller.  Using snapshots - enabed VSS or not, is not supported by MS, and you will have problems.

• If all the domain controllers reside in the VMWare environment

  I was curious to know if there is someone who can give their opinion about the location of the domain controllers in the VMWare community.  I had 2 DCs before the introduction of VMWare and pulling on servers inside.  I created 2 new controllers domain in VMWare and then retrograde 2 those outside so that only there are only virtual domain controllers.  It seemed to work very well, but I had to turn off equipment running VMWare, and when it started, the storage device that the accessible ESX host has launched a mistake because he could not find a domain controller.

  Most people remove all external domain controllers and go with only VMWare virtual DCs, or is it better to always keep an external domain controller upwards and running?  Any advice is welcome.

  Thank you.

  I always advise to keep the domain controller hosting your virtual environment PDC emulator FSMO role. Time is critical on most of the servers, but especially on the PDC that is the top of your Windows Time synch infrastructure.

  We also keep a ms in each data center on a physical platform, this way if we already have a power down when we turn we can raise the physical DC first and very quickly.

  I hope this helps.

  Kind regards

• Satellite Pro C650D - problems with the audio and game controllers

  Hello

  I recently had problems with my microphone and speakers/headphones and game controllers.
  Sometimes the microphone stops working when on Skype, for example, but most of the time works fine, once again, when I restart the pc.

  Stakeholders sometimes still work when I connect headset.
  Some of the sounds are still coming through the speakers while some coming through the headphones.

  I have a usb game controller which also did not work everything properly.
  If I assign buttons in the program that they do not work in the game.

  All these devices are in Device Manager in a group that makes me think it's sort of annoying update doubtful that messes with them.

  Any body have similar problems or know what to do better?

  Hello

  Can you please send some details on the laptop model and the system you are using?

  With regard to the issue of sound/mic:
  > The microphone sometimes stops working when on Skype, for example, but most of the time works fine, once again, when I restart the pc.

  Are you talking about internal microphone or external? This only happens using Skype?
  In your case I would test the microphone using different applications to make sure that is not a Skype related issue.

  > Yet sometimes the speakers work when I connect headset.

  I put t think its problem of laptop in my opinion, you must make sure that the controller is compatible with the games you play and also recommended to check some info provided by the manufacturer of the game controller.
