The Local Security Authority cannot be contacted Remote Computer: hostname or http://www.petenetlive.com/KB/Article/0000826 ip The Reason There are myriad reasons why this could crop up. However, for me it has always beenone: User must change password on nextlogon Under many situations (such as when the local computer isn’t a member of the remote computer’s domain) https://blog.mnewton.com/articles/Solution-RDP-The-Local-Security-Authority-cannot-be-contacted/ the Remote Desktop Connection application can’t handle the prompt to change a user’s password when Network Level Authentication isenabled. One step forward, two stepsback With previous versions of the RDP protocol, a user was allowed to change their password graphically after signing on. However, NLA has no such provision, at least the way it’s implemented in RDC. So, if you have to change your password you are SOL unless you can get to aconsole. Workaround In my case, I was able to sign on to a domain member’s console using the VMware vSphere Virtual Machine Console. When I did that, I got a friendly password changescreen: After setting a new password, subsequent Remote Desktop logons workfine. Enable JavaScript to view the comments Matthew Sojourner NewtonRSS
Server Hosting Colocation Remote Desktop Connection: An authentication error has occurred. The Local Security Authority cannot be contacted Fixing login problems with Remote Desktop Services http://www.riptidehosting.com/blog/remote-desktop-connection-an-authentication-error-has-occurred-the-local-security-authority-cannot-be-contacted/ If you have having issues logging into a Windows Server with Remote https://theregime.wordpress.com/2015/09/10/rdp-error-local-security-authority-cannot-be-contacted/ Desktop Services, below are some things to try. For example, some users have seen an error like this when trying to login “Remote Desktop Connection: An authentication error has occurred. The Local Security Authority cannot be contacted”. First, check if your issue is affecting all users authentication error or just one account – can the administrator login? Does user have correct permissions to access the server via RDP – are they are member of the Remote Desktop Users group in User Permissions? Does the Firewall allow RDP connections? What port is used? Is a VPN connection required? Login as computername\username (i.e. SERVER1\jdoe) instead if just typing jdoe authentication error has at the RDP login prompt. (this seems to be required if using the MAC RDP client). Computername is the name given to the server, which you can see under computer properties If only affecting one user, try to reset the users's password and uncheck the box by "change password at next logon". In 2008 R2, login as administrator, open server manager (which may open automatically), expand tree on left side to get to users and groups, select users, right click on user name and say “set password” to reset password, then go in properties of user and uncheck change at next logon. In 2012 R2, click on start button, type “computer management” which will open and expand tree on left side to get to users and groups as noted above. Do not use the “user much change password at next logon” button in user properties. Various comments and posts online indicate that changes in the windows authentication process in recent OS versions don’t allow expired users to change their password via R
