I got an impression that the OP is trying to deploy something (maybe the entire Cygwin) onto an NFS share.  So the named FIFO "file" is also created in there.

It's pointless to assume that the FIFO can be used as a communication device between the hosts that can mount the share, but it can be quite feasible to envision a scenario, in which the same host opens the FIFO located on the share from two processes and establish the communication using that special "file" (which is basically a special data-less i-node).
