addresses assigned to the devices have changed, you can use the Resolve IP Addresses wizard to rediscover
these devices and resolve the status.
The Resolve IP Addresses wizard retrieves a list of all the devices that are currently in a communication error
status, regardless of the reason for the communication error. For each of these devices, the wizard retrieves
the hostname assigned to the device, and then looks up the hostname in the Domain Name System (DNS) to
determine if the corresponding IP address has changed. If a new IP address has been assigned to the device,
the wizard adds that device to a list of devices to be rediscovered. The wizard then runs a Specified Addresses
discovery using this list of devices to be rediscovered. If there are PC-connected devices and network-
connected devices in a communication error status, the wizard runs a separate discovery for each group of
devices.
If you know that the IP addresses assigned to some of the devices on the network have changed, you can run
the Resolve IP Addresses wizard one time to resolve the status of those devices. If the IP addresses assigned
to the devices on the network change frequently, you can create a schedule to run the wizard on a recurring
basis, such as daily, weekly, or monthly.
To resolve devices that are in a communication error status, perform the following steps:
1. Go to Tools > Resolve Device Communication Failures. The Resolve IP Addresses wizard starts.
2. To run the discovery immediately, leave the Schedule checkbox cleared.

installed. You should be aware of the potential for time and date differences when configuring
schedules.
