Duplicate cluster names in network

I'm setting up several Weblogic servers for Oracle Forms and Reports. The Portal Forms Reports Discoverer installation/configuration installs managed servers and clusters with default names, and doesn't explicitly configure a unicast channel for the clusters.
We will be working with several Weblogic installations in our network (a production cluster and at least 4 test clusters), which will be able to see each other on the network. The clusters will all have the same default cluster names, and will all use the default unicast channel. We will only use the Forms and Reports functionalities from these clusters, we won't configure any services like JMS or JDBC.
Should I worry about these clusters conflicting with each other, if I don't configure a separate unicast channel per cluster? Or is there no need to worry, because Forms and Reports don't really use the unicast channel anyway?
Besides the Forms and Reports clusters, we will also configure some separate clusters in which we will deploy J2EE applications, which will use JMS and JDBC. Just like the Forms clusters mentioned above, these will also be a production, and several test clusters, on the same network.
These clusters will be entirely configurable by us, but the applications will use non-configurable JMS and JDBC names, which might cause conflicting JNDI-names on the network.
Am I correct in assuming that we need to configure one of the following (or both) for these J2EE application clusters?:
- Create a uniquely named network channel for protocol cluster-broadcast, to use as a unicast channel.
- Create each cluster with a unique name, so the separate clusters on the network will 'know' which managed servers are its members, and which messages to ignore.
Regards,
Peter.

Cluster network name resource 'Cluster Name' failed registration of one or more associated DNS name(s) for the following reason: The handle is invalid.

I'm stuck here trying to figure this error out.
2003 domain, 2012 hyper v core 3 nodes. (I have two of these hyper V groups, hvclust2012 is the problem group, hvclust2008 is okay)
In Failover Cluster Manager I see these errors, "Cluster network name resource 'Cluster Name' failed registration of one or more associated DNS name(s) for the following reason: The handle is invalid."
I restarted the host node that was listed in having the error then another node starts showing the errors.
I tried to follow this site: http://blog.subvertallmedia.com/2012/12/06/repairing-a-failover-cluster-in-windows-server-2012-live-migration-fails-dns-cluster-name-errors/
Then this error shows up when doing the repair: there was an error repairing the active directory object for 'Cluster Name'
I looked at our domain controller and noticed I don't have access to local users and groups. I can access our other hvclust2008 (both clusters are same version 2012).

Now, I'm stuck on adding a managed service account (mas). I'm not sure if I'm way off track to fix this. Any advice? Thanks in advance!

Thanks Elton,
I restarted 3 hosts after applying the hotfix. Then I did the steps below and got stuck on step 5. That is when I get the error (image above). There
was an error repairing the active directory object for 'Cluster Name'. For more data, see 'Information Details'.
To reset the password on the affected name resource, perform the following steps:
From Failover Cluster Manager, locate the name resource.
Right-click on the resource, and click Properties.
On the Policies tab, select If resource fails, do not restart, and then click OK.
Right-click on the resource, click More Actions, and then click Simulate Failure.
When the name resource shows "Failed," right-click on the resource, click More Actions, and then click Repair.
After the name resource is online, right-click on the resource, and then click Properties.
On the Policies tab, select If resource fails, attempt restart on current node, and then click OK.
Thanks

The name 'rolename' is in use by the cluster already as network name or application name

I removed windows cluster ISCSI target server few days back since it was not needed and now its needed as we need since its a clustered storage space and we need this role for ISCSI storage to external server. Now when I add the role again I get this error
The name winiscsi is in use by the cluster already as network name or application name
I double check role is not installed . I even rebooted both nodes

Hi Adnan-Vohra,
Could you post the original error information or the screenshot about this error, I can’t find out any similar error explain, we can not install the iSCSI target on any cluster
node we need the separate server as the shared storage.

Cluster resource 'SQL Network Name (SQLCLUS1)' of type 'Network Name' in clustered role 'SQL Server (DB1)' failed.

Cluster resource 'SQL Network Name (SQLCLUS1)' of type 'Network Name' in clustered role 'SQL Server (DB1)' failed.
Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it. Check the resource and group state using Failover Cluster
Manager or the Get-ClusterResource Windows PowerShell cmdlet.
I keep getting this error message. Can someone please help. Thank You.
Kranp.

Hi Kranp,
As the issue is more related to Windows Server high availability
, I recommend you post the question in the
Windows Server High Availability (Clustering)
forum. It is appropriate and more experts will assist you.
Besides, there are similar threads regarding to the above error for your reference.

NLB Error: NLB detected duplicate cluster subnets. This may be due to network partitioning

We're running two servers in a datacentre, call them WEB1 and WEB2 in unicast NLB mode.
Each server has a public NIC, the NLB adapter and a private NIC for communication between hosts. We have a VLAN between the public NICs so the cluster IP is routed to both hosts. I can access the Virtual IP just fine, and hosts can talk on the separate private
network. The public NICs are connected up to a Cisco switch with a VLAN between two ports, one for WEB1 and one for WEB2 (all done by the datacentre).
Intermittently on WEB2, I lose connection from my local machine and the Event Logs show multiple:
NLB cluster []: NLB detected duplicate cluster subnets. This may
be due to network partitioning, which prevents NLB heartbeats of one or more
hosts from reaching the other cluster hosts. Although NLB operations have
resumed properly, please investigate the cause of the network partitioning.
WEB1 works just fine and doesn't suffer from these issues. Removing WEB2 from the NLB cluster leaves everything working fine (with just the single WEB1 left).
Perhaps unrelated but for WEB1 & WEB2, the interface metric for the private NIC is 10 while the public NIC is 20 (although 'route print' shows much higher values around 270-300). [seems this is correct according to http://blogs.technet.com/b/tristank/archive/2004/06/08/150734.aspx]
Really hoping someone can help as NLB seems a great solution!
Thanks ever so much

Hi, no luck with this I'm afraid. Both NICs are configured the same, not sure what you mean by the NIC binding order. Cabling is definitely fine.
We're just sticking it out. As this is running on a live set up I had to get things working so put the NLB cluster into Single Host mode with WEB1 as the default host. This meant traffic worked fine while I still had frequent disconnections to WEB2.
After about 24 hours, the error stopped. When anything changes the cluster, ie one of the servers is restarted for updates, it does this error for about 24 hours then settles down.
I have no idea if the Single Host mode is helping this or not - perhaps it just takes 24 hours for it to settle down. Would it also settle down if I wasn't in Single Host mode? No idea and won't try it as its a live set up. Is NLB working properly? Most
probably not! However if WEB1 dies, WEB2 does take over connections all itself and works fine till WEB1 comes back online (requests go back to WEB1) and WEB2 starts to disconnect for the roughly 24 hours.
Anyone from the Microsoft Networking team able to shed any light on this? Please?

SQL Developer 2.1.0.63 duplicate TNS names displayed in the Connection Type

I'm running SQL Developer 2.1.0.63. The New Connection window displays duplicate Alias names when you select the Connection Type of TNS. I've made sure that the TNS_ADMIN variable name is all in upper case in the Environment Settings but I haven't had any luck eliminating the duplicates. I've tried filling in the TNSNames directory on the preferences setting but this didn't help either. I've also checked my system and I don't have multiple version of TNSNAMES (we keep a public copy on a network share). Does anybody have any suggestions?
We also have SQL Developer 1.5.5 and we don't have this duplicate problem in that version.

I found the problem, it was in the TNSNames file. SQL Developer 2.1 is more sensitive to a messy TNSNames file. This past fall we reworked our environment with new hardware and OS software, during the multiple rounds of testing we created various temporary test databases. The entries that were added to the TNSNames file never got cleaned up and in some cases were added in a random fashion. After I went in and cleaned up some of the old, dead entries I noticed that there were duplicate entries for one of our Development databases. After I removed the duplicate entry in the TNSNAMES file all of the duplicates displayed on the Connection Type screen disappeared. Problem solved.

SQL cluster name on a Windows Failover Cluster

Hello,
I am installing a SQL cluster (first timer) using Windows server and SQL (both 2008 R2)
Windows failover cluster is setup and functioning. I am now installing the SQL failover cluster part.
Question: What should be the "SQL server network name", should it be the same as my Windows cluster name or different name ?
Thanks for your help,
Luca

It should be different, this is known as the virtual SQL Server name in earlier versions of SQL Server failover clusters.
SQL Server Network Name —
Specify a network name for the new SQL Server failover cluster. This is the name that is used to identify your failover cluster on the network.
https://msdn.microsoft.com/en-us/library/ms179530.aspx?f=255&MSPPError=-2147217396
This will be the name used to identify your cluster on the network. This is the name that will be available on the
network for the clients to connect SQL instance.

2012R2 hyper-v failover cluster Cluster name object has no DNS record created

I’m trying to setup a 2-node ws2012R2 cluster using ws2008R2 AD(with DNS) but got an issue with DNS entry creation on AD. I also tried ws2012 AD but it's the same problem.
The individual node DNS entries were created on AD automatically upon joining AD but I can’t get AD to create DNS entry for my cluster name object automatically. AD will have cluster name computer
created but no record for cluster name in DNS entries
Got the following event ID 1196 error with the info below.
Cluster network name resource 'Cluster Name' failed registration of one or more associated DNS name(s) for the following reason:

NLB detected duplicate cluster subnets - Exchange Server 2010 SP3 CU5

Hi All,
I will explain the environment first, there are:
-Two HUB/CAS servers (WNLB)
--HUBCAS01
--HUBCAS02
-Two Mailbox servers (Failover Clustering)
--MAILBOX01
--MAILBOX02
*All servers are updated to Exchange Server 2010 SP3 CU5.
The issue is that from recently outlook users are disconnecting from the outlook and cannot be joined to the exchange server unless if I drainstop or stop HUBCAS01. Furthermore, if I start HUBCAS01 from WNLB it will work fine for sometimes yet it will randomly
disconnects outlook users from exchange again (For ex: next day morning).
So far when I search deeper in Event log, there is an warning event log:
Event ID 18: NLB cluster [192.168.*.*]: NLB detected duplicate cluster subnets. This may be due to network partitioning, which prevents NLB heartbeats of one or more hosts from reaching the other cluster hosts. Although NLB operations have resumed properly,
please investigate the cause of the network partitioning.
Now I hope you will provide this link to resolve this issue - http://technet.microsoft.com/en-us/library/cc726421(v=ws.10).aspx
But I don't think that this will resolve this issue, as i have tried this for 3 times, yet no luck. Please help me to resolve this issue permanently. Thanks in advance.

Hi,
The issue is mainly related to the HUBCAS01 server. To deep investigate the issue, you need to take RPCTrace from the Outlook client and see the details. Even more, it’s better
to take a Network trace to check the details of the network.
Thanks,
Simon Wu

1068 Error when bringing cluster name resource online

Hello Guys,
I have configured 3 node cluster setup on windows 2012R2 machines. When I try bring the networker name resource online, I got following error and name resource failed become online
"Network Name resource 'Cluster Name' (with associated network name 'DEDUPCSV') has Kerberos Authentication support enabled. Failed to add required credentials to the LSA - the associated error code is '1068'."
Can anyone please helpme to resolve this problem.
Thanks,

Hi Ajith G,
Could you confirm every node the “Network List Service” service is running or not, if this service stopped please start it, after you start this service if the issue still
exist please run your cluster validation then post the warning and error part.

Is Access Point name and cluster name same, if we have only 1 access point ?

if we have only 1 Access Points, will the name of access point be same as the cluster name ? can i create more then 2 cluster on same role ?
sid

Hi sid,
You can not create a role same with your cluster name, it will cause the DNS resource confilect.

SCC Cluster name failed to come online on perticular node

Hi all,
I'm working on a 2-node SCC cluster that I've had up and running for quite a while. For some reason now, I cannot move one of my CMS' to a particular node. I am getting two events in the event viewer: 1207 & 1069.
1207 from event viewer is:
Cluster network name resource 'Network Name (EXG)' cannot be brought online. The computer object associated with the resource could not be updated in domain 'ADI.local' for the following reason:
Unable to obtain the Primary Cluster Name Identity token.
The text for the associated error code is: An attempt has been made to operate on an impersonation token by a thread that is not currently impersonating a client.
The cluster identity 'CLUS$' may lack permissions required to update the object. Please work with your domain administrator to ensure that the cluster identity can update computer objects in the domain.
"EXG" is Exchange application instance (CMS)Network name which is failing on perticular node. Find cluster log below for more info
So, my question is, does anyone know what needs to be done in Active Directory to rectify this problem?

Admin share access denied via cluster name

on a windows 2008 two node failover cluster if access \\node1\e$ it works fine. But i am not able to access using cluster name \\cluster network name\\e$.
has anyone faced same issue, kindly advise

Hi,
As in other answers and my post above this is no longer the working method. If you looked at the "
\\cluster-name\c$ " the CNO has no C drive ! this is only a network name!
It is not common that you access the cluster disks other than the node disk by \\CNO\
you should connect \\nodename\c$ and if there is a cluster file share you could connect as
\\Filenodename\sharename and not
\\CNO\sharename if the CNO moves to a other node and the named e$ is than on the other node. Bad way to access the data!
so C$ should only been accessed by \\clusternodename\c$

Duplicate computer name Windows XP

Hello,
I applied Security Update 2011-005 this morning. Now when my Windows XP clients are rebooted, they pop up a message "Duplicate computer name exists on the network." Looking in the XP System event log points the finger at my iMac as refusing to allow that name. Unplugging the iMac from the net fixes the issue.
I have about 200 computers inside my firewall, probably 90% Windows (either XP or 7 Pro). This problem hits multiple XP computers, all with unique names.(so, yes, my single Lion client prevents dozens of XP systems from accessing the Windows network)
I looked at the iMacs Netbios name, it is "13-155-8" which seems to be the last three octets of my dhcp IP address. (35.13.155.8) I have no idea how it came up with that, I've never bothered assigning one.
Seems to be related to Macs keep assuming Netbios names causing Windows computers to get error but the fix there doesn't apply.

Hi and welcome to Discussions,
as it seems Netflix not only needs Windows but also the Internet Explorer 6.0 or higher, so from the Mac OSX side you have no luck, since the latest IE for Mac is 5.0.
I would suggest getting BootCamp from Apple http://www.apple.com/macosx/bootcamp/
and of course a valid Windows XP SP2 or Vista license/package.
Have Fun
Stefan
