windows requiring network credentials pw to access mac RRS feed

  • Question

  •  have 2 pc's -- one winxp and one win 10.  whenever i try to access the mac from either one of the pc's for file sharing, a "windows security" dialog box opens wanting a UN and PW.  i was advised to set all (mac and both pc's) with the same login pw -- i did but to no avail.  the pc's still want the network pw.  i can however access the pc's from the mac without a pw.  what is so baffling is that i have never, to my recollection, set up a pw on either of the pc's.
    the mac has yosemite  10.10.2 (if that's relevant).   don't know where to go from here-- any help greatly app.  tks in adv
