I’m having trouble understanding what is meant in http://technet.microsoft.com/en-us/library/cc753945(v=ws.10).aspx where it says “If you enable this policy setting, a user will be prompted on the client computer—instead of on the terminal server—to provide credentials for a remote connection to a terminal server” in the section for *Prompt for credentials on the client computer**. If the user is prompted on the client computer instead of the terminal server, what’s it authenticating against? And the last line in that section discusses the difference between 2008 and previous versions, it says for server 2008 the user will be prompted on the client to provide creds for the remote connection.* * * *Can anyone help me understand what this means?* Windows 2003 and 2008 The reason for this is because we have an environment running on a manufacturing floor using Arista AP-3200 thin clients that utilize ThinManager for configurations and on the older 2003 systems we can have the account and password that is used to start the session stored in the configuration and the clients automatically logon and start the HMI application. But in 2008, it always prompts for the password to start the session. We have the security within the HMI application instead of relying on the OS because of an issue within the application. I'm not sure that the article is related to our issue but I couldn't make sense of what the difference of being prompted at the client or at the server is. -- Thanks, Scott D.
