I have the following problem.
I have a server running windows server 2008 r2 standard, I have configured with the AD domain users.
I have a specific user who logs into the computer and when accessing the server by \ \ server appears a username and password to authenticate, as I place calls but does not work, and if change \ \ server to the server IP el esolicita password but it works perfectly.
and as soon as this user on another computer works fine without asking for any password.
What would be the problem?
