PING: host unreachable
This means that the IP address is currently unreachable. This
is indicative of a network problem. The router sent the
message either to the specific network to which the IP
address belongs or to a default gateway. If it was sent to
the specific network and the network was learned via RIP,
there is probably a temporary network 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 OfficeConnect Remote 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 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 a workstation on the local LAN, get to an
MS-DOS prompt and type
ping <remote IP address>
<enter>
where the remote IP address is the address of a
host on the remote network (Ex: ping 10.0.0.12). If no
