Hyper V - Logon Issue - you cannot log on because the logon method

After a server reboot now when i try to log on to 2 DC servers ( Alpha & Beta) via Hyper V Manager i get the following error on both servers -  you cannot log on because the logon method you are using is not allowed on this computer.
I'm logging on using the domain administrator account which i've always used.

I can only log on to 1 of the servers (Beta) using RDP . When i do so it appers that the domain controllers are down probably becuase i cant login to the PDC (Alpha)

Are you able to log on via RDP to Alpha?

What OS is the host and the guest DCs?

When logging on do you see any symbols below the password field that indicates Smartcard or other authentication method?

Did someone enable Smartcard only in a GPO?

the host and guests all have windows 2008 std
I dont see any symbols below the password field and nobody enabled smartcard in a gpo.

Do you have a snapshot to go back to before the reboot? (why did you reboot--were any changes made before that?)

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

I've revert to a backup from last Friday and i get the same issue , i didnt reboot , the san that the vm's are on powered off /on over the weekend
Lionel MMSmall Business IT ConsultantCommented:
So before the reboot (power failure) you had the same problem?  When was the last time you could logon?
pcstech-mwarrenAuthor Commented:
i think it might be to do with the the rpc service  , i think another service might be stopping it from starting
Lionel MMSmall Business IT ConsultantCommented:
If that is the case you can connect to the server using "services.msc" from another PC/Server and browsing to the server and checking the services

i stopped the information store service and rebooted and now i can connect with rdp. Although the rpc service weas started , info store was using the same port and got to it first.

At least im on alpha now but the login via hyper v manger still exisits , from reading forums most people are pointing towards a gpo permissions issue.

Hi Philip,

The problem was sbs remote operators group was in the deny logon locally policy on the defauly domain controller policy  see below for resolution....


No idea when that group was added to that policy

One should never edit the two default policies that come out of the box. :(

Always create GPOs and make settings changes in them.

Glad to hear that it got worked out.
