No logon servers available to service the logon request on SBS2011

 I have a SBS2011 virtual machine on Hyper-V server.
 In SBS2011, I changed the boot type to SAFE MODE and restarted it. But when I enter the password at the logon screen, it says: "There are currently no logon servers available to service the logon request".
 I waited 24 hours and still I get the same error message when I enter the password.

Can you help?

HyperV IP@Andrew,
Hyper-V server was originally set to receive IP informaiton from SBS2011 VM DHCP Server. Since SBS VM was in Safe mode, Hyper-V server had no IP information. This morning I assigned a static IP (please see the screenshot) to Hyper-V server and all of a sudden, I can log in as domain admin and restarted SBS VM in normal mode.
This evening, I am going to remove IP information from Hyper-V server again and restart SBS VM in safe mode to see if I can make this problem re-occur.
I will report back.

As a rule we don't join standalone hosts to the guest's domain. Use the local admin to log on if the guest DC is offline.
