Unable to Initialize NICs on Windows Server 2008 R2 CORE edition

Microsoft has seen under certain conditions Windows 2008 R2 Core Server may not be able to detect new network cards or is not using both interfaces on a dual interface NIC on a machine with multiple NICs.
 
The problem has been found when a user replaces the motherboard and another known issue seems when you add a dual port network card. It fails with an “Error 31 - A device attached to the system is not functioning”

The bold error code(REGDB_E_CLASSNOTREG) indicates that net class installer failed to instantiate CLSID_InstallQueue COM object (handles pending install work items) because this class object is not registered with the system.
The failing function is net\config\netcfg\engine\dihook.cpp:netcfgx!HrInsertItemIntoInstallQueue.

1. A possible workaround to use would be to use KB929852 (http://support.microsoft.com/kb/929852) to disable IPV6 by setting [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents] to 0xffffffff.

2. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\
3. Double-click DisabledComponents to modify the DisabledComponents entry.
4. Type any one of the following values to configure the IPv6 protocol, and then click OK:

a. Type 0 to enable all IPv6 components. (this is the default setting)
b. Type 0xffffffff to disable all IPv6 components, except the IPv6 loopback interface. This value also configures Windows Vista to use Internet Protocol version 4 (IPv4) instead of IPv6 in prefix policies.
c. Type 0x20 to use IPv4 instead of IPv6 in prefix policies.
d. Type 0x10 to disable native IPv6 interfaces.
e. Type 0x01 to disable all tunnels IPv6 interfaces.
f. Type 0x11 to disable all IPv6 interfaces except for the IPv6 loopback interface.

5. After a reboot use the command devcon.exe remove NICVendor_DRV\L2ND&PCI_*
6. devcon.exe rescan
