DNS name resolution issue with nmap on windows

[Guru Prateek Pinnadhari <guruprateek89 () gmail com>]

Im using the command "nmap -sn -R x.x.x.x/24" to get a list of all host up
in the network.


While it works fine on a linux machine including DNS names, I observe the
following on a windows :
(command modified a little to explain the issue)

DNS name resolution skips hosts here and there ( usually all alternate host
names are dropped)

Any idea why this happens or is there a workaround?

Thanks!
Guru
