The installation of System Center 2012 Virtual Machine Manager will fail with the following error if the NetBIOS name for the VMM server exceeds 15 characters:
The Virtual Machine Manager server could not validate user Domain\ComputerName.
Contact your Virtual Machine Manager administrator to verify that there is a two-way trust relationship between the user domain and the domain of the Virtual Machine Manager server.
NetBIOS names longer than 15 characters are not allowed (see KB909264 - Naming conventions in Active Directory for computers, domains, sites, and OUs - http://support.microsoft.com/kb/909264). When a server is deployed and the server's NetBIOS name is longer than 15 characters, AD NetBIOS Name changes and truncates the server name. For example "MyVMMServerName01$" gets changed to "MyVMMServerName$".
To resolve this issue, rename the VMM server so that the NetBIOS name does not exceed 15 characters.
