With the internet off, check:
ping from client to server by name
ping from server to client by name
Send us /etc/hosts, /etc/host.conf, /etc/hosts.*, /etc/nsswitch.conf
Do you have a firewall that perhaps is changing config depending on
internet status? What firewall do you use?
Relavent error messages:
1. take a copy of /var/log/syslog on each machine.
2. Try to mount an NFS directory
3. Record any visible error messages on either box
4. Take another copy of /var/log/syslog on each machine and diff
with the previous copy, and send the diffs, snipping off
extraneous or sensitive data.
Good luck,
Doug.
