Setup for System Center 2012 Virtual Machine Manager crashes when the server name exceeds 15 characters

Applies to: System Center 2012 Virtual Machine Manager

Symptoms


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.

Cause


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$" gets changed to "MyVMMServerName$". 

Resolution


To resolve this issue, rename the VMM server so that the NetBIOS name does not exceed 15 characters.
