problem. If the network is a static entry in the routing
table, it may have been entered incorrectly.
PING: timeout waiting for reply from <IP
Address>.
The host network is probably reachable but there is no
answer from this IP Address. There are a couple of possible
explanations for this: The IP Address might not be assigned
to any unit; the path from the OCR 812 to the unit is so
slow that the PING response did not get back in the
allotted time frame; or there may be a temporary break in
the path.
DNS Errors
Network Name: <name> could not be resolved.
Network Name: <name> could not be resolved due
to a problem interacting with the Name Server.
The name could not be resolved. Either no DNS server was
located or the server(s) did not have the name in the host
table list. This error will also appear if the user entered an
invalid IP address such as 10.100.100.256.
Network Name: <name> could not be resolved due
to a timeout on the request.
No response was received from the DNS server to which
the DNS request was sent. This could be due to a network
connection problem or Internet congestion.
Option 2: DOS Ping to ISP or Remote Site Network
1 From the workstation on the local LAN, access the MS-DOS
prompt and type
ping <remote IP address> and press
<Enter>, where the remote IP address is the address of a
host on the remote network (Ex: ping 10.0.0.12). If no
address was provided, contact the ISP or the remote site
administrator for an IP address to ping.
2 The OCR 812 will send the PING request. A reply from
10.0.0.12 indicates success.
An example script of a failed ping is:
C:\ping 10.0.0.12
Pinging 10.0.0.12 with 32 bytes of data:
