With NLA enabled, the user is "pre-authenticated" before any desktop and related processes are created. It is recommended to have all Terminal Servers (RDS) use NLA at all times. XP Service Pack 3 and Remote Desktop 6.0 support NLA but it is not turned on by default which means you may simply not connect or see the error "An authentication error has occurred (Code:0x507)".

I honestly don't know what changes were made, but I DO know that some were.Round about the same time, my Remote Desktop Connection to another system stopped working. When trying to connect from my WinXP machine to my Win7 machine, I started getting the following error:An authentication error has occurred (Code: 0x507).Anyone know what might have happened? My next step is to reload a restore point of a couple weeks back, but I'd like to avoid this if there's a simple fix.Thanks for any help. Solved! Go to Solution.

Solved (0x507) error when trying to Connect to TS 2008 from XP SP3 Posted on 2010-08-23 MS Server OS Windows XP Windows Server 2008 1 Verified Solution 11 Comments 4,376 Views Last Modified: 2013-11-21 I have terminal services set up on a Windows server 2008 that is also a domain controller. I have no issues connecting to it remotely through machines running Windows 7. However, I have several machines running XP SP3 that cannot seem to connect. I get to the initial log in screen in TS which authenticates no problem. It is when I launch an application and enter in my credentials that I get the RemoteApp error: An authentication error has occurred (Code: 0x507) Remote computer: {domain name} Any help would be appreciated 0 Question by:B00m3r Facebook Twitter LinkedIn Google Best Solution byB00m3r I was able to resolve the issue.
