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 for the report. Could you post debug output (-d9)? Also, to
copy short Nmap cmd.exe output, you can use the following procedure:
-d9 will produce quite a lot of output. I suggest you to redirect it
to a file, this way:
nmap -sn -R 10.0.18.2 10.0.18.3 >log1.txt
nmap -sn -R 10.0.18.3 10.0.18.2 >log2.txt
Could you then send us the log1.txt and log2.txt, so we could see more
about what is going on?
