I have just setup a new (well rebuilt) Windows PC for my wife to use and I am trying to set it up so my wife can print to the printer I have connected on my Mac mini (Yosemite). I have sharing enabled on both and on my mini I have shared the printer. From my Mac I can see the files located on the PC that I've setup to share, so that tells me that I can see the PC from my mini. But for some reason I can't access anything on my mini from the PC. I have enabled both File and Printer sharing on the mini. Any suggestions of things to check? Thanks for your help. Additional information - if this helps on the PC side, when I try to access the Mac, it keeps asking for credentials but for the life of me I can't figure out what it is asking for. I've tried my logins for my Mac and my PC and it rejects then both.
