  Use the windows task manager to make sure, if you like, or something like
process explorer from www.sysinternals.com

  IIUIC the cygwin dll recreates them if they're missing any time a cygwin
app fires up.

  If you really can't find a running task, that suggests that it's some
service that's been installed with cygrunsrv.  What was that you were saying
about an rsyncd?  What does the output of "net start" show you?

Can't think of a witty .sigline today....
