While being logged on to the new 2008 R2 domain controller and all services are running I could not connect to this domain controller on a AD level.
I wanted to transfer the Schema Master role to this new server but when i opened the Operation Master (from Active Directory Schema) i could not change it because i was not connected to the server to the server i self. But to the server holding the roll at the time.
When i wanted to connect to the server itself i saw the status unavailable.
This happens when you disable IPv6 on the network card on a DC.
the solution for this is to add or change a registry entry.
go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\
open the DisabledComponents item. If the item is not there than make one (DWORD (32-Bits) value.
and give it one of the following values:
Type 0 to enable all IPv6 components. (Windows default setting)
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.
Type 0x20 to use IPv4 instead of IPv6 in prefix policies.
Type 0x10 to disable native IPv6 interfaces.
Type 0x01 to disable all tunnel IPv6 interfaces.
Type 0x11 to disable all IPv6 interfaces except for the IPv6 loopback interface.
I gave it the 0xffffffff value and after a reboot the “problem”was solved.
