Hello!

Our VMM Server 2008 R2 manages 6 lusters Hyper-V 2008 R2.

One had a problem, so I decided to remove and add it again.

Trying to add, it returnos the following error:

• my.cluster.fqdn is not listed in Active Directory Domain Services.
• Verify that the computer name and the domain name are correct, and then try the operation again.
• ID: 10403

When I try to add using the "Skip Active Directory Name Verification", the job sarts and then:

• Error (415)
  Agent installation failed copying E:\Program Files\Microsoft System Center Virtual Machine Manager 2008 R2\agents\I386\2.0.4521.0\msiInstaller.exe to \\my.cluster.fqdn\ADMIN$\msiInstaller.exe.
   (The network name cannot be found)
• Recommended Action
  1. Ensure my.cluster.fqdn is online and not blocked by a firewall.
  2. Ensure that file and printer sharing is enabled on my.cluster.fqdn and it not blocked by a firewall.
  3. Ensure that there is sufficient free space on the system volume.
  4. Verify that the ADMIN$ share on my.cluster.fqdn exists. If the ADMIN$ share does not exist, reboot my.cluster.fqdn and then try the operation again.

I cant access access the path \\my.cluster.fqdn\ADMIN$ using Windows Explorer, but if I try each node name \admin$, it access ok.

Any idea how to solve this?

Hi Elton!

Thanks for helping.

Firewall are all disabled on all related servers. 

But I didnt try to access the shares from the DCs before. I tried just now, and the name resolves OK but it doesnt work for the cluster name. 

Cluster is OK, I can do live migrations OK, Cluster validation only shows warning for pending updates, but both servers show no updates when running windows update.

PS C:\> setspn -L myclustername

Registered ServicePrincipalNames for CN=myclustername,OU=HOST,OU=SERVERS,OU=VCA,OU=COMPANYNAME,DC=COMPANYDOMAIN,DC=com,DC=
br:
        MSServerCluster/myclustername.redebahia.com.br
        MSServerCluster/myclustername
        MSServerClusterMgmtAPI/myclustername.fqdn
        MSServerClusterMgmtAPI/myclustername
        MSClusterVirtualServer/myclustername.fqdn
        MSClusterVirtualServer/myclustername
        HOST/myclustername.fqdn
        HOST/myclustername

PS C:\>

Any other idea?

I tried to access other clusters \admin$ share, and I couldnt, got same error.

But when accessed the \\clustername, all of them ran OK, including the problematic one. 

Once this VMM Server manages other 5 clusters hyper-v, I removed one other to re-add, just to check if really the problem is only with that one. 

I added again (the cluster I removed) and it added successfully. 

So, the problem is with this specific cluster.
