RDP Connection Authentication Error

0

I have a AWS Server running Windows 2012R2. I have been using it for long and it works fine. Today I changed 2 group policy settings i.e.

-Accounts: Limit local account use of blank passwords to console login only - disabled
-Network access: sharing and security model for local accounts to Guest only

After I restarted the server I am unable to connect to the server using RDP. This happened because of the group policy settings that I changed. How to fix it as I can't connect via RDP?

When I try to connect it gives error: "An Authentication Error has occurred. The local security authority cannot be contacted. This could be due to expired passwords. Please update your password if it has expired."

I have 2 user accounts (admin & standard) and both have passwords.

Please help as its urgent.

Thank you

Issue resolved, just reversed the registry entry by accessing server through AWS Session Manager.
