We have some devices in Fault Monitoring Device Administration known by IP address (i.e. did not resolve using the local hosts file). For others there seems to be no problem reading the hosts file. In version 3.x one could delete the devices and request a resynch with DCR. The online Help suggests that there should still be a Delete option in version 4.0 but there is no such button on the page. How does one persuade DFM to use the local hosts file to resolve the IP address for devices already in "Known" state?
