Cannot log in after moving server

We are really scratching our heads on this one.

We moved 3 Dell PowerEdge servers with Fedora 12 x86_64 from one datacenter to another. 2 of them are fine but the 3rd we cannot log into any more.

The KDE login screen comes up, the user names are shown, but our passwords don't work.

Going to the console, we cannot log in as root with the password either.

Also, I set up shared keys for ssh between the 3 boxes so that I could ssh between machines without entering my password -- that doesn't work either. This one is one of the head scratchers since /home is on a different disk.

I'm 1,600 miles away and the tech that went into the cage to try from the console does not know Linux. Dunno how he got picked...

What exactly would have been corrupted to cause this behavior -- unable to login locally AND ssh authorized_keys no longer works?

Oh, and apparently they were initially able to get into the machine from the console after the move since they were able to configure the NICs. But now we can't.

We know how we can get a root login on a reboot from GRUB, but we don't know what to look for as far as what might be wrong with the system once we're in.

Any thoughts/pointers would be greatly appreciated. My backup plan is to go out with the DVD and try to rescue the system or simply reinstall it.

The Red Hat family distros do not like to be moved around. Haven't found a cure myself yet.
