I have the three following laptops all connected to the same network and the same band on that network or, in the case of the Windows machine, connected via ethernet. My router is a Netgear Nighthawk AC1750 and my modem is a Netgear DOCSIS 3.0 340 Mbps Cable Modem.

Laptop A:

Gigabyte 15 inch P35 BWx V4
Intel i7 5th Gen
Windows 10


Laptop B:

Macbook Pro 13 inch 2011
Mac OSX 10.8.5 (Mountain Lion)
Intel i5 3rd Gen


Laptop C:

Macbook Air 11 inch 2015
Mac OSX 10.10 (Yosemite)
Intel i5 5th Gen


I set both Apple laptops up for file sharing with the ability for everyone on the network to read and write to the shared volumes connected to them. AFP and SMB/Windows File Sharing Settings are all enabled.

I set my Windows laptop, in the Network and Sharing Center, as shown in the screenshots provided by the link. I have tried fiddling with these settings a bunch already.

I have no passwords or usernames setup for any of my laptops, and they all login automatically.

Initially I was able to access both Mac machines from my Windows machine (which is what I wanted) without any problem. Then, seemingly spontaneously, my Windows machine began prompting me for login credentials for the Macbook Pro only. There are no login credentials for that machine, so this makes no sense to me. I can still access the Macbook Air just fine from my Windows machine over the network, but the Macbook Pro is inaccessible in this manner. My problem is that I would like to fix this networking error and regain access to my Macbook Pro over the network from my Windows machine.

I have included a link below to a shared Google Drive folder with relevant screenshots and text files with network settings. Thanks for any help you guys can provide.

Info for Tom's Hardware
 
1) FYI, I'd add that I have a WDMYCLOUD (mine is 4TB) which I use to share files between computers. It attaches to the router and can be easily seen by any computer.

2) I doubt the following will help, but I have in the past linked computers with a Gigabit switch to share the router, but any device attached to the switch just goes through the switch to talk to each other.

3) *Not my area of expertise, so not sure if this is useful to you:

So thanks for your reply, but none of that solves the problem for me, and while I appreciate the info most of it seems like it would further complicate the issue. I'd rather not have to buy new hardware at the moment, and the third bit isn't quite what I was looking for. Thanks anyway. I would like to add that this appears to have been a problem in Windows 7 at least, in the past, as I found when performing a Google search. I was unsuccessful in finding a solution however, or at least one that I could apply to my problem.
 
So as it turns out all I had to do was enter my username into the prompt and leave the password field blank. Still weird that it was asking for credentials, but the problem appears to be solved now anyway.
 
Okay, so now it is happening again and no longer accepting the correct user name at all. The weird thing is that it seems to be an intermittent and unreliable problem. I have re-enabled the link for the files on my Google Drive.
