Cannot Login to EC2 Instance As Local User After Joining SimpleAD Directory Service in AWS
I have an EC2 Windows 2012 r2 instance that is joined to Directory Services (SimpleAD directory).
Before joining the server to my SimpleAD I was able to login as the local Administrator yesterday.
I have created a local administrative user but I cannot login as that User. I can login as a Domain Administrator, but not locally. Obviously this is different than yesterday.
I've tried several things, including omitting the domain name when attempting to RDP and adding
The error I am getting is "Login Attempt Failed".
I have not changed any Group Policy.
Any suggestions on how I can login to the machine as a local user?
Thanks for your help.

Thank you, but that's not the issue. I have the Administrator password. What's really happening is that when this server was connected to a Domain, I couldn't login as any local user.

To resolve this, I removed the computer from the Domain and associated it with a temporary Workgroup. I was then able to login locally. I then logged back out and in as the local account again, adding the machine to the Domain.
My best guess is that this has something to do with SimpleAD (Directory Service from AWS). I'm going to leave this up for the rest of the day to see if someone else has experienced this as well and, if so, what the fix was.

Great suggestion. I will let AWS know. Thank you.
If that password doesn't work, you should be able to log on to the instance using the Administrator account you have been provided via SImpleAD. Using that account, you should be able to RDP to the EC2 instance you joined and reset its local administrator password.
