The Windows authentication FAILED (error 6L) usually refers to permissions errors. The Remote Agent software/service might not have enough privileges to authenticate Windows Accounts. In that case you might want to refer to the attached document, sections "Configuring for Domain Controllers Authentication" or "Configuring for Member Server Authentication". You should check the one that applies for your installation depending if the RA is installed on a Member Server or Domain Controller on your AD Domain.
Also, remember that Windows Authentication for AD Domains running Windows Server 2008 was included on ACS 188.8.131.52 Patch or above. As a recommendation, an upgrade to 184.108.40.206 latest patch would be the best approach. If the issue persists after the upgrade you might need to check the attached document Post-Installation Tasks under the sections mentioned above.
