hi,

I cant able to login with any account even local administrator, while login it shows "the sign in method you are trying to use isn't allowed. For more info, contact your network administrator"

Please help me out on this problem

Thanks & Regards,

Hi,

I am supposing there is a group policy which prevent user from log in. if you are not the administrator of your environment, please report this issue to your domain administrator.

If you are administrator of domain, please refer to following thread for reference.

There are 3 or 4 group policy or solutions, give it a try.

How are you trying to log in?  Locally, via remote, VPN, etc?
