I have an SBS 2011 server, in trying to solve a different problem I found articles saying disable ipv6, on rebooting the server just hangs on "applying settings" this was for over an hour until I switched the server off.
On further searching I now know that switching off ipv6 was crazy.
If I try to start the sever in safe mode or SM with networking I get to the logon screen enter the details and I get "there are currently no logon servers available to service the logon request"
Where do I go from here please!!
