Hyper-V failed connect via WMI 'failed credentials'

Veeam Logoby msullivan@csa1.com » Sat Jan 07, 2012 12:26 pm

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.

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