How To... Resolve Comm Issues When the DNS/DHCP Device Connected to the Server
is Power Cycled
Certain drivers support DNS/DHCP resolution for connectivity. These devices also allow users to assign unique Domain/
Network names for identification purposes. When starting and connecting to the network, the devices will request an IP
address from the Network DNS server. This process of resolving a domain name to an IP address for connectivity takes
time; thus, for greater speed, the OS will cache all of the resolved IP/Domain names and then re-use them. The
resolved names are held in cache for two hours by default.
If The Server Fails to Re-Connect to a Device
This issue normally occurs when the name of the IP address (associated with the device's Domain/Network) changes. If
the change is a result of the device being power cycled, it will acquire a new IP. It could, however, also be a result of
the IP being changed on the device manually. In both cases, the IP address that was being used no longer exists.
Resolving the Problem
The server automatically flushes the cache every 30 seconds; thus forcing the IP to be resolved. If this does not resolve
the issue, users can manually flush the cache by typing the command string "ipconfig /flushdns" in the PC's command
prompt.
