Network communications Problem
Issue
- Since midnight last night, we have not been able to access our server's VIA hostname, but we CAN access them via IP address.
- Immediately we thought that there was a DNS problem, but DNS is working fine, and the servers are all resolvable.
- /etc/resolve.conf and /etc/hosts all appear to be correct as well.
Environment
- Red Hat Enterprise Linux 5.5
