Troubleshooting
WinDiscovery
uses bi-directional UDP messaging on port
6163 for both the discovery process and to communicate
configuration and status packets to and from the NTP
network device(s). Delivery of UDP messages/packets is not
guaranteed. If you experience intermittent problems with
WinDiscovery
, try closing the current session and restart
the application. If this does not resolve the issue try the
following trouble shooting tips, or switch to an alternate
method of configuration such as
Telnet
.
LOST PASSWORD
Possible reasons and
solutions:
A password cannot be recovered if it is lost or forgotten.
Reset the MDN to the factory default configuration using
the procedure described in the section, “
Configuration
”
(page 10). Then the unit can be reconfigured and provided
with a new password. The default password will once again
be “
public
.
”
UNABLE TO FIND/DISCOVER THE MDN DEVICE
ON THE NETWORK USING WINDISCOVERY
Possible reasons and solutions:
1.
The discovery process was not complete before
selecting device(s). After clicking [
Discover
], wait until
the status indicates 100% completion.
2.
Verify that all network cables, hubs, etc. are in proper
working order. Be sure that Ethernet cross-over cables
are not being used where inappropriate.
3.
Verify that the network device is on the same physical
network as the computer from which you are running
WinDiscovery.
If the computer is separated from the
device by a router or a firewall it is likely that the
router/firewall is blocking communication with the
device. Run WinDiscovery from a computer within the
remote network, or ask a network system administrator
to configure the router/firewall in question to pass
through (both directions) UDP broadcasts on port 6163.
If this does not resolve the detection problems you may
additionally configure to pass through both directions
UDP broadcasts on ports 6165, 6166, and 6264.
4.
Verify that the hub/router/switch is capable of
supporting the 10mb speed that the attached network
device requires.
