Error 2912 when a Virtual Machine Manager 2008 and 2008 R2 operation fails due to a certificate issue: "Element not found (0x80070490)"
Article ID: 971264 - View products that this article applies to.
When you use System Center Virtual Machine Manager 2008 to perform any action that involves file transfers across virtual machines, such as new VM or new P2V, the operation fails and generates the following error message:
An internal error has occurred trying to contact an agent on the %serverName%.
(Element not found (0x80070490))
Ensure that the agent is installed and running. Ensure the WS-Management service is installed and running, then restart the agent.
0x80070490 = Element not found = Certificate not found
Note The exact error message that is displayed in the console is generic in nature and will contain an error code such as 2912 or 3154. However, the message will always contain "Element not found" in the description.
This problem occurs because the certificate is missing from the VMM server or because of an issue that affects the Host certificate, such as an incorrect name or the use of IP instead of FQDN or NetBIOS.
To identify and verify this issue, you must capture a trace by using the Dbgview tool. For more information about this process, including where to download the Dbgview tool, click the following article number to view the article in the microsoft Knowledge Base:

The following is a snippet from the stack trace that was collected when this error occurred. Notice the point at which the operation checks for the certificate on the VMM server. Another key to this problem is the BitDeployer.Copy function.

To resolve this problem, remove the managed host from the VMM server, and delete any residual certificates from the host on the VMM server. Then, re-add the host. To do this, follow these steps:
SCVMM uses BITS to transfer payload between SCVMM managed computers. These data transfers are encrypted by using a self-signed certificate that is generated at the time that a host computer is added to VMM. If these certificates are corrupted or missing from the VMM server or from the managed computers, the payload deployment job can fail. Deleting the certificates and re-adding the host causes the certificates to regenerate.
