That should print "1" EnableLinkedConnections is a DWORD value and should be set to 1. > $ uname -a > CYGWIN_NT-10.0 Vidyo-LT0519-10 2.3.0(0.291/5/3) 2015-11-02 11:15 x86_64 C= ygwin >=20 > Is Windows 10 the same?

There should be no FileNetworkOpenInformation call anymore for Netapp and the PrlSF filesystem. Does Cygwin correctly recognize the FS? What does `mount' print? It should print `type prlfs'. Can you please once again call `/usr/lib/csih/getVolInfo.exe Z:' and `/usr/lib/csih/getVolInfo.exe Y:' and paste the output here? I'm not quite sure because the original getVolInfo call returned a filesystem type of "PrlSF", not "PrlFS" as I had expected. Cygwin now checks for "PrlSF".
