Hello, anyone can tell me how I can fix the "Login timed out after 60 seconds" error, when the system is not even taking 60 seconds, since as soon as it loads, it gives this error when am trying to enter my login details. I have access to the system's files using WinSCP, so if I need to change any file settings will not be a problem... I am on a 7.04 Ubuntu server

It may be a clock syncronization problem. Make sure all your systems are getting clock updates using NTP. You can either use an internet NTP server such as NIST, etc, or you can set up a local server on your LAN which will keep all the PC's updated locally, yet it will keep updated from the Internet - allowing a large LAN installation to minimize the amount of NTP traffic going out of the firewalls.
