We have a single server with a static IP address that acts as a file server. No DNS, no DHCP. We have a DLink DIR-655 router as well that does the DHCP. All the other clients have dynamic IP.
When pinging the server by IP address, there's a response. When pinging or trying to reach it by hostname, there isn't a response. All the dynamic clients are working with both their hostnames and IP addresses.
Manually entering in an entry to the host file of a client alleviates the problem of reaching the server via hostname, but any idea why the computer suddenly can't be reached by hostname? I thought it was the router. Isn't my router supposed to have a cache for local DNS?
