Virtual Domain Controllers in 2012 Failover Cluster. Time Skew
Hi All,
Not sure if this is the correct space for this topic, however i'll give it a go anyway.
We have a 2 Hosts (HP DL385) Windows Server 2012 Failover Cluster.
Storage is provided by a 12 Bay NAS with iSCSI connections (This is catering for CSV's and Quorum)
We are running 2 Virtual domain controllers (2008R2)
The issue we experience is that if the cluster goes down, and when it comes back online the time on the domain controllers (one or the other or both) skews by any where up to 3 days which causes havoc for our office until we can resync clocks with the PDCe.
Time Synchronisation Integration Service is disabled on both Domain Contollers
A few days back we need to reboot the storage on the cluster, and the tasks performed were as follows:
-Power off all virtual machines (Graceful Shutdown)
-Put all CSV's into maintenance mode
-Offline Disk Witness to Quorum
-Rebooted Storage (Waited until it came back online)
-Online Quorum Storage (Successful)
-Bring CSV's out of maintenance mode (Successful & Browsable)
-Power on all Virtual Machines (Successful)
This is where the time Skewed and caused headaches. The time for some reason went to 2 days 11hrs in the past on 1 domain controller.
With this DNS lookups failed to work, Cluster services failed, Cluster Aware Updating Failed, RDP to VM's (and Virtual Hosts) by DNS Name failed (Date time error)
There doesn't seem to be anything in the EventLog except for date/time stamp on events being 2 days in the past.
Now this is why i'm not sure if the issue is cause by fail over clustering, or is an issue with the domain controllers.
Any advice regarding this or if anyone has seen this behaviour before any info would be great
Thanks
Rob
Hi Rob,
Does both this two DCs on your cluster VM and there have not others DCs? Microsoft recommends that files for virtualized domain controllers be placed on non-CSV
disks, Non-CSV disks can be brought online without authentication. Because non-CSV disks can be brought online more easily.
For virtual machines that are configured as domain controllers, it is recommended that you disable time synchronization between the host system and guest operating
system acting as a domain controller. This enables your guest domain controller to synchronize time from the domain hierarchy, please confirm your PDC time is always correct.

Windows 2012 Failover Cluster - File server role (vCO)
Hi,
I wonder if anybody can shed some light on a query i have.
A windows 2012 failover cluster will be built in AD domain example.uk. Cluster File server roles will be created and will reside in this domain also.
We also have a requirement to run a cluster file server role in the child domain off secure.example.uk. Is this possible? or do the file server roles and related vCO's have to reside in the same domain as the cluster (CNO).
I know the CNO can be used to create the VCO but could a prestage a VCO in the child domain of secure.example.uk.
MarkHi Mark,
By default CNO will create
VCO automatically in default domain computer OU, we generally use the
KISS principle to place the CNO and VCO to the same OU, and as far as I know there no known design document indicate the VCO can be placed in different domain, therefore I suggest you place the CNO and V CO at same OU.

FTP in Windows 2012 Failover Cluster
Hi,
Understand that Windows 2012 is having much improved Failover Clustering features,however i have faced issues when i configured FTP in Windows 2012 Failover Cluster.
1) As per the process configured the shared disk for FTP data path.
2)Installaed FTP feature in both Nodes of Clustert
3)Finally created the Generic Service in Cluster Roles for FTP Service.
After the configuration i found everything working fine but when i try to failover the FTP role found that FTP resource is not moving smoothly. Also i observed that Microsoft FTP service gets in to "starting" mode in the destination Node. To run the FTP
resource Microsft FTP service should be in Started mode.
This happens only when we try to failover else it works fine if you start freshly.
Have any one tried this? Any clue about such issue ?
Regards:MaheshHi,
In earlier versions of Internet Information Services, Microsoft provided generic resource monitor components to support high availability Web server instances by using the Microsoft Clustering infrastructure. However, custom code was needed to fully realize
the potential of this solution. Also, the generic scripts that Microsoft provided did not satisfy customer needs.
From IIS 7 to configure IIS in a clustered environment by using Windows Server failover clustering, you have to use a custom (scripting) code to enable such a high availability scenario.
Note:
We recommend that administrators carefully evaluate the use of Network Load Balancing (NLB) instead of using failover clustering as the primary and preferred method for improving the scalability and availability of Web applications that have multiple servers
that are running new IIS (from IIS 7) . One benefit of NLB is that all servers can actively participate in the concurrent handling of incoming HTTP requests. Another benefit is that in an NLB IIS environment, it can be much easier to support rolling updates
and rollbacks while still providing high availability of Web applications.
To configure high availability for IIS FTP servers using Failover Clustering:
Install the Web Server role on all cluster nodes.
Install the Failover Clustering feature on all cluster nodes and create the cluster.
Set up a file share that will be used for IIS shared configuration
Configure the IIS shared configuration on all cluster nodes
Configure Offline Files for IIS Shared Configuration on all cluster nodes
Configure the FTP site and specify the location of its content on one cluster node
Configure high availability for your FTP site by creating a generic script in Failover Cluster Manager
For more detailed configuration procedure please refer to following MS articles:
Note: I didn’t find IIS 8 in Windows Server 2012 failover cluster configuration guide, below guide was published for II 7 in Windows server 2008 and Windows Server 2008 R2, but its basis configuration procedures should also apply to Windows Server 2012.

I have two windows 2012 host server that are clustered using windows failover cluster feature. Each server is hosting four VMs. When migrating from Host2 to Host1, the migration failed with the following error:
Cluster resource 'Virtual Machine Configuration SCPCSQLSRV01' of type 'Virtual Machine Configuration' in clustered role 'SCPCSQLSRV01' failed. The error code was '0x569' ('Logon failure: the user has not been granted the requested logon type at this computer.').
When this happens, the VM that I was migrating can no longer be started even on the original host. The only remedy is to restart the host server.
Any suggestion on resolving this problem?
Thanks
IkadThanks. The article referred to above gives the solution to my issue. There is a group policy that is applied to the OU where the host servers were placed. Doing gpupdate /force temporarily removes the problem. Unfortunately the NT Virtual Machine\Virtual
Machines account is a special account that cannot be added like other accounts and granted the log on as a service right. The thread
http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/d56f2eae-726e-409a-8813-670a406593e8 contains how it can be added which is by creating a group and running the command
Net localgroup VMTest “NT Virtual Machine\Virtual Machines” /add
to add it to a local group VMTest. VMTest is then assigned the right to log on as a service.

Packets sent out the wrong Interface on Hyper-V 2012 Failover Cluster
Here is some background information:
2 Dell PowerEdge servers running Windows Server 2012 w/ Hyper-V in a Failover Cluster environment. Each has:
1 NIC for Live Migration 192.168.80.x/24 (connected to a private switch)
1 NIC for Cluster Communication 192.168.90.x/24 (connected to a private switch)
1 NIC for iscsi 192.168.100.x/24 (connected to a private switch)
1 NIC for host management with a routable public IP (*connected to corp network) w/ gateway on this interface
1 NIC for Virtual Machine traffic (*connected to corp network)
All NICs are up, we can ping the IPs between servers on the private network and on the public facing networks. All functions of hyper-v are working and the failover cluster reports all interfaces are up and we receive no errors. Live migration
works fine. In the live migration settings i have restricted the use of the 2 NICs (live migration or cluster comm).
My problem is that our networking/security group sees on occasion (about every 10 minutes with a few other packets thrown in at different times) syn packets that are destined for the 192.168.80.3 interface goes out of the public interface and is dropped
at our border router. These should be heading out of the 192.168.80.x or 192.168.90.x interfaces without ever hitting our corporate network. Anyone have an idea of why this might be happening? Traffic is on TCP 445.
Appreciate the help.
NateHi,
Please check live migration and Cluster Communication network settings in cluster:
In the Failover Cluster Manager snap-in, if the cluster that you want to configure is not displayed, in the console tree, right-click Failover Cluster Manager, click Manage a Cluster, and then select or specify the cluster that you want.
If the console tree is collapsed, expand the tree under the cluster that you want to configure.
Expand Networks.
Right-click the network that you want to modify settings for, and then click Properties.
There are two options:
Allow cluster network communication on this network-- Allow clients to connect through this network
Do not allow cluster network communication on this network
If the network is used only for cluster node communication, clear “Allow clients to connect through this network” option.
Check that and give us feedback for further troubleshooting, for more information please refer to following MS articles:

SQL Server 2012 Failover Cluster configuration questions
Hi,
I have few questions on , SQL Server 2012 Failover cluserting pleasse provide suggestions:
1) In SQL Server 2012 is there a configuration for active / passive Failover Cluster installation? If so how is it done? if you could provide any links or articles that would help.
OR
Is this been replaced by Always ON Availability Groups?
2) Also in our environment we have done active/active installation but at a time my understanding is only node has the ownership to the shared storage versus both the nodes, is that correct? If not please provide an explanation?
Any additional information would be valuable in clearing my doubts?
Thank youy
Malini=Hi malinisethi,
If you install SQL Server in a cluster and configure Active-Passive cluster. In the first node, select “New SQL Server Failover Cluster installation” option , when we are installing Active-Passive cluster, we have to specify one virtual/network name. (Note:
For Active-Active clustering you have specify different network names as per the number of nodes). on the other nodes is similar to installing on the first node except that we have select the Add Node to a SQL Server failover cluster option from the initial
menu. For more information, there is a similar issue about SQL Server 2008 Active-Passive/Active-Active cluster installation, you can review the following article.
http://sqldbpool.com/2009/10/07/sql-server-2008-active-passive-cluster-installation/
About Active/Active SQL Cluster, two clustered SQL Server instance are created in different nodes. Then apply Active /Active configuration of both instance. There is an example about creating an Active/Active SQL Cluster using Hyper-V. you can review the
following article.

Having a problem creating 2 node cluster. I launch FCM, begin the process of adding nodes. Node 1 goes in fine. Node 2 gives an error which is, "unable to connect to xxx.xxxx.com via WMI. This may be due to networking issues
or firewall configuration.
Node 1 and 2 are virtual. Have tried them on the same metal and on different metal.
Any advice would be much appreciated.Hi shageman0304,
Unfortunately, the available information is not enough to have a clear view of the occurred behavior. Could you provide more information about your environment. For example,
the exact text of any error? When this problem occurs the system log record information, screenshots is the best information.
If you have install any third party software on this node please disable or exit them, please install the Recommended hotfixes and updates for Windows Server 2012-based failover
clusters updates then monitor this issue again.
Recommended hotfixes and updates for Windows Server 2012-based failover clusters
http://support2.microsoft.com/kb/2784261
After install the updates, if the issue still exist please performing the following steps:
1. Open Task Manager on the affected server and check if the wmiprvse.exe is running if not please enable the wmi service.
2. Restart wmi service.
3. Restart the server.
Please rerun the validation test then post the error part, that report will quickly locate the issue.

SQL 2012 Failover Cluster to 2014
Hi,
we have recently purchased SQL 2014 std edition with SA (VLSC), one of our guy downloaded SQL 2012 instead of 2014 by mistake and installed as failover cluster. I wanted to ask whether should I upgrade to SQL 2014 or uninstall SQL 2012 and install 2014 fresh.
In 2014, secondary server used for failover support does not need to be separately licensed for sql server as long as it is truly passive and primary SQL server is covered with active SA.
We have installed 2012 in other fashion, 4 cores on primary and 4 cores on secondary, now we just want to assign 8 cores to primary and 8 to secondary to get 2014 benefit. Is it possible using upgrade or a fresh install is required.
I Appreciate inputs from experts.Hello,
You can upgrade the cluster using the instructions provided on the following article.

Windows Server 2012 Failover Cluster (Hyper-V) Event Id 1196
Hi All,
I just installed Failover Cluster for Hyper-V on windows server 2012 with 2 nodes. I got following error event id 1196.
reCreated / deleted Cluster Host A record on DNS and nothing happened.
Any suggestion?
There is similar topic but it couldnt help
http://social.technet.microsoft.com/Forums/en-US/winserverClustering/thread/2ad0afaf-8d86-4f16-b748-49bf9ac447a3/
RegardsHi,
You may refer to this article to troubleshoot this issue;
Event ID 1196 — Network Name Resource Availability
http://technet.microsoft.com/en-us/library/dd354022(v=WS.10).aspx
Check the following:
Check that on the DNS server, the record for the Network Name resource still exists. If the record was accidentally deleted, or was scavenged by the DNS server, create it again, or arrange to have a network administrator create it.
Ensure that a valid, accessible DNS server has been specified for the indicated network adapter or adapters in the cluster.
Check the system event log for Netlogon or DNS events that occurred near the time of the failover cluster event. Troubleshooting these events might solve the problem that prevented the clustered Network Name resource from registering the DNS name.

RBS Licensing on a SQL Server Standard 2012 Failover Cluster
I am planning to implement a Sharepoint 2013 installation which is primarily to be used for Document Storage. We are considering using Sharepoint RBS with Filestream with SQL 2012 Standard and as far as I can see on our non-production environments this works
without any issue - i.e. we enable filestream and RBS with Sharepoint and SQL and everything works as expected on our non production systems. In non production we have single SQL Server nodes.
However, in production we have planned to have a 2 node SQL 2012 Standard failover cluster.
On this page, it indicates
"To run RBS on a remote server, you must be running SQL Server 2008 R2 Enterprise on the server that is running SQL Server where the
metadata is stored in the database."
My question is : Am I entitled to use RBS with Filestream on a SQL 2012 Standard Failover Cluster, or is SQL Enterprise required.
If enterprise is required, we will have to remove the RBS. I have reviewed the links below, but cannot see a definitive answer from a licensing perspective

Indeed, in Microsoft official document, all SQL editions (Express, Standard, Enterprise…) of SQL Server 2008 and SQL Server 2008R2 support RBS (Remote Blob Store), however, as your post, if you run RBS on a remote server, we recommend you use Enterprise
version especially you want to deploy Remote BLOB Storage with SQL Server 2012 in Production environment. Usually, Enterprise edition is more for mirroring, supporting more RAM/CPU, and custom RBS providers and multiple nodes cluster.
If you had setup and configured RBS successfully with SQL Server 2012 standard, and now you need to want to upgrade to SQL Server 2012 Enterprise, I recommend you reconfigure your blob store, you can review the following similar article.
https://community.dynamics.com/ax/b/axdilip/archive/2012/10/22/configuring-and-implementing-sharepoint-2010-rbs-remote-blob-storage-with-sql-server-2012-part-1.aspx

SQL 2012 failover cluster\mirroring VS AlwaysOn for VDI?
Hi, we have to build high availability SQL 2012 cluster for VDI and we have two options. One option is to build a server cluster with combination of failover and mirroring and other option is to build failover cluster with AlwaysOn.
We are not sure which option to chose. We have contacted Microsoft support to provide us some documents and instructions for failover\mirroring combination but they have send us instructions for AlwaysOn option.
What would be best way to build high availability cluster for VDI? Also, since first option is very complicated, we would appreciated if someone could provide us with some documentation for it (how to build it, what to look out for, etc.) because that is the probably the option we are going to use.
Thank you in advance.

Server 2012 Failover Cluster No Disks available / iSCSI
Hi All,
I am testing out the Failover Clustering on Windows Server 2012 with hopes of winding up with a clustered File Server once I am done.
I am starting with a single node in the cluster for testing purposes; I have connected to this cluster a single iSCSI LUN that is 100GB in size.
When I right click on Storage -> Disks and then click 'Add Disk', I get No disks suitable for cluster disks were found.
I get this, even if I add a second server to the cluster, and connect it to the iSCSI drive as well.
Any ideas?Hi All,

For testing purpose you'd better spawn a set of VMs on a single physical Hyper-V host and use shared VHDX as a back clusterd storage. That would be both much easier and much faster then what you do. + it would be trivial move one of the VMs to another physical
host, shared VHDX to CSV on a shared storage and go from Test & Development to production :) See:
Shared VHDX

Restoring Virtualized Domain Controllers
http://technet.microsoft.com/en-us/library/d2cae85b-41ac-497f-8cd1-5fbaa6740ffe(v=ws.10)#backup_and_restore_considerations_for_virtualized_domain_controllers
The article above has an illustration to determine the best way to restore a virtualized DC. I have
several questions about this chart.
1. The step titled "Deploy the
VHD against a new VM, and restart in normal mode" - Must a new VM be created in HyperV,
or can the VHD just be replaced with a backup?
2. The
steps titled "Restore the Virtual machine instance that predates the failure" - Is it really necessary to start in DSRM mode and set this registry value if the backup is an application consistent, image based backup where what you are doing is restoring
the VHDX file?
3. What
will happen if you restart a Domain Controller that in good condition and go into DSRM mode and set the "database restored from backup" to 1?1.
The step titled "Deploy the VHD against a new VM, and restart in normal mode" - Is it really necessary to create a new virtual machine? Why can't the existing virtual machine get used and just replace the VHDX file?
In the scenario, it is assuming that the VM failed to start. That is why you create a new VM and attach the VHD file.
2. The
steps titled "Restore the Virtual machine instance that predates the failure" - Is it really necessary to start in DSRM mode and set this registry value if the backup is an application consistent, image based backup where what you are doing is restoring
the VHDX file?
When going to DSRM mode and doing a non-authoritative restore of the DC, you will be asking the DC to take its DB content from other DCs. You can apply this when you have no backup and you cannot get back in time with a healthy state of the DC. In other
words, you can simply re-install the DC, do a metadata cleanup (Seize FSMO roles if it is an FSMO holder) and promote it again. Of course, this suppose that you have health DC/GC server in your domain before doing that.
By the way, I do not see that this step is required when you restore from the VHDX in the chart. Please correct me if I am wrong :)
3. What
will happen if you restart a Domain Controller that in good condition and go into DSRM mode and set the "database restored from backup" to 1?
It will do a non-authoritative restore.

Assistance would be greatly appreciated
Thank you
JabuHi jsibeko,
Since the VMware offer the MSCS shared storage solution themselves, I suggest you first ask VMware whether that shared storage is supported with your vSphere edition, I found
some VMware KB about the VMware shared storage for MSCS, may you can get more tips.
The VMware KB:
Microsoft Clustering on VMware vSphere: Guidelines for supported configurations (1037959)
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1037959
Microsoft Cluster Service (MSCS) support on ESXi/ESX (1004617)
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004617
I’m glad to be of help to you!
