Hyper-V failed connect via WMI 'failed credentials'

Post by msullivan@csa1.com »

Hello
We have just installed Veeam 6, accepting defaults, on Windows Server 2008 R2 SP1.
I'm trying to add a server 'Hyper-V standalone' using the local administrator account, and we recieve the following error:

Unable to connect Via WMI.HostName:[xx.xx.xx.xx]
User credentials cannot be used for local connections


I have tryied setting up a new account with full administrative rights and recieve the same erorr.
FireWall is turned off. Also, if i click 'Ports' button, all components show failed to connect.

Hello Matt,

Could you please tell me if you're trying to add Hyper-V host, where Veeam B&R server is installed?

Thank you!

Yes, we have Veeam installed on the host server running 3 vm's.
I had been trying to add the server as a 'Microsoft Hyper-V server (standalone).

So, I tried adding the server as a 'Microsoft Hyper-V cluster and receive the same error in the following topic.

RPC Error adding Hyper-V Server http://forums.veeam.com/viewtopic.php?f=25&t=9991

Firewall is turned off, and I tried to disable the anitvirus, but we still get the error.

Hello All,

I know this thread is old and probably different, but I ran into this issue in my test environment when I executed a "files to tape" job.
I get the following error;
"Failed to create shadow copy for G: Error: User credentials can not be used for local connections".
G here indicates the G:\ of my physical VB&R and Tape server.

My environment:
-Tape Server: Dell R320 (VB&R server)
-Tape library: NEC LTO5 LL009F Autoloader (directly connected to the above server via SAS cable)
-SAS Card: HP Smart Array P212 (identified as NIC2 by the OS for reasons unknown)
-Tape drive: IBM ULTRIUM-HH5 SCSI sequential device
-Media changer: NEC LL009F Media changer

I have not created any user and therefore logs in as the administrator. I do not understand the above error.

Your comments will be very much appreciated.

Thanks.
