possible network issue

In the redcay lab 3 of the 6 machines were stuck booting up. They were complaining about networking errors, but didn't get any further, not even timing out. After 3 hours of trying to find what was happening, they started working again. No changes had been made to the software. Early on I actually had ruled out networking, since that was my first suspicion, but I had swapped the cable with an adjacent working one, and it still misbehaved.

The only other thing that I did to two of them is boot them up with a rescue cd and manually configure the networking.

The other problem is that Pam was refusing local logins because it couldn't contact the ldap server. It is unclear to me what the problem is in the configuration files.
