If you uncheck "Use Reverse DNS Lookup", then the discovery process will not do any lookup (and that is the reason the option for sysname is greyed out in GUI)
So, all devices will be shown with IP addresses.
1. Make sure that you have entries in your DNS server for sysNames on devices. That is, lookup on IP address must return the sysName of the device and reverse lookup on this sysName must return the "same" IP address.
2. Check both the options: "Use Reverse DNS Lookup" and "Resolve By Sysname".
If the reverse DNS lookup based on sysName is successful, then you will see devices in DCR with their sysName. Otherwise, the devices will still be shown with their IP address.
If the devices are in DCR, then use the export feature in DCR to export them to a csv file. MS Excel should be able to read the csv file and you can get the sysNames and IP addresses from it as a list.
