I am trying to create a new user named "Shop" with a password of "SHOP" who would be a member of the group "users" on a stand alone XP SP3 machine. I have created and deleted this user several times both using the control panel User Accounts icon, and the local users and groups under Computer Management. After creating the user, when I log off as Administrator and log back on as Shop, Windows thinks about it for 30 seconds or so, and then loops back to the "press ctl-alt-del to login" window. If I change Shop to an Administrator, I can log on with no issues. If I log off and change Shop back to the "Users" group, I get the login loop. I tried Local Security Policy - Log on Locally Properties, and added Shop to list under Local Security Setting. It now lists Administrators, Backup Operators, Guest, Power Users, Users, and Shop. This did not seem to change anything. I am still stuck. Only members of the Administrators group can log on to this PC. What am I missing?
