Couldn't you reproduce the problem in your environment with my test case? Release note of iperf 2.0.5-1 says: Note that a currently known limitation of the Cygwin version is that running as a daemon (with the -D option) is not currently functional. The previous version (2.0.4) also had this limitation.
