Time different on client machine and server prevents login
Posted on 2007-10-03
I have a customer with a laptop and when he heads back to his docking station after being out of the office for a day or two (not in a different time zone), he tries to login to the network and his laptop stops the login and reports an issue where his local time is different than the server, and disallows him to login. As i've been researching, this is caused by Kerberos security relying on correct time between a client machine and the server. I had the customer disconnect from the network, login as the local administrator, plug back into the network, log off, log back in as himself, and that time around he was able to login fine.
The odd thing is though when he logged in as the local admin, the time on the laptop was indeed correct
Anyone have an idea why this is happening? It's happened to him in the past, and i've done this with him again and again to patch the issue.
