I have user that isn't able to map any network drives that she has access to. Everytime she tries to get to map drive it ask her for her username and password. Everytime she put in her credentials, it just pops the screen backup asking for credentials again. I tried logging into another machine with the same user account and I wasn't able to authenticate and it kept saying that I had wrong username or password. So what I did was I created a new account to see if this is just with her user account.
I created a testad (username) user account and logged onto my machine.I logged on successfully, however I tried to map a network drive and it asked me to put in username and password to share folder again. I put in testad and password and it didn't do anything except ask me for password again. I tried my admin account and it allowed me to map network drive.
Another weird thing is I tried to verify permissions on the directory/folder I'm trying to map to for both accounts and when I select permissions for folder, hit add and enter the user/object name testad, it says An object named "testad" cannot be found. I tried the initial user account and I got the same response. It's as if these users don't exist. What is going on? I had another tech try to log in on his machine with the new account I created and he couldn't even log on to the system. Not sure what is going on and how to test my AD or troubleshoot this issue. I checked event viewer and I saw no suspicious errors. I RAN dcdiag and no errors. I appreciate anyones help and support.
