I have searched through some of the results that come up for the hanging on boot issue and most deal with hardware issues before the windows splash screen from what I have come across so far. I have a bit of a different twist however. Two users who travel the globe frequently are complaining of their Dell Latitude Laptops (one is 600 and the others is a 610) hanging on login. The normal bootup screens show, the users are always prompted for the username and password. The computer will start the login process and go as far as showing the users background. However, no start-up music, icons never appear on the screen, and ctrl+alt+del yields no reposnse. The users have allowed this to sit attempting to login for up to half hour with no response still. The only solution is to force the computer off by holding the power button and then going in through safe mode. Occasionally doing this and then the machine returns to working fine after a reboot, and then will go into another freezing episode maybe two or three boot-ups later.
This is a hit or miss problem. Never happens when they are in the office. Always when they are traveling it seems. I am having a hard time with it because I have been unable to re-create the problem thus far. That and the computers are in the office probably 5 days out of every three months. Problems just seemed to start in the last two months. Have several users who travel but the two this is occurring with are two of my heaviest travelers.
Any ideas, troublshooting tips?
