hi,

were tried connect virtual machine in local host or in remote hyper-v server?

is hyper-v host server standalone server or domain member?

> including localhost/administrator , null password

did mean standalone server , administrator has null password? set password administrator , check result.

also may modify following group policy settings:

1. start gpedit.msc.
2. expand computer configuration, , expand administrative templates.
3. expand system, , click credentials delegation.
4. in details pane, double-click allow delegating default credentials.
   
   note if using ntlm authentication, use allow default credentials ntlm-only server authentication entry.
5. click enabled, , click select concatenate os defaults inputs above check box.
6. click show, , verify computer of remote user included in list. if necessary, click add, , include computer of remote user. can use wildcard characters. example, select computers, add following wildcard character:

*

1. click ok 2 times.
2. close group policy.
