SCVMM is failing to add a Host with an error saying:
VMM is unable to complete the
request. The connection to the agent
hostservername.domain.local (name changed to protect innocent) was lost.
(Unknown errror (0x80338126))
Host machine: Server 2008R2 Std – Only role is Hyper-V
SCVMM Machine: Server 2008R2 Std – Roles include: IIS, WSUS, File Server.
Domain: Windows Server 2003 functional level. Domain controller is a Small Business Server 2003 SP2 DC.
WinRM is configured on both servers and winrm id -r:servername commands successfuly return details between both machines. Server's can be remotely administered by use of Server Manager from a third machine.

Debugview Trace output has the following line of interest:

Error getting cluster details for

0AD4.0FCC::02/04-01:29:13.471#09:ClusterHelper.cs(570):
System.Management.ManagementException:

Any help gladly appreciated 🙂 I've reinstalled SCVMM w/ factory defaults, reenabled WinRM on both boxes, and disabled Windows Firewalls, everything I can think of.

Solution: The agent somehow got installed but not correctly onto the host during the process. Removing this agent and manually installing it onto the host allowed SCVMM to add the host with no problems.
