How Do I Log Into A Mac To Share Files From A Windows Pc

I was using a great guide by Jackson Chung (https://www.makeuseof.com/tag/how-to-easily-share-files-across-mac-windows-computers/#comments) to set up an Office workgroup between my MacBook Pro and my Windows Home PC.

I did everything in the guide and set up two shared folders from my Mac. I can now see and log into my Mac from my Windows’ ‘Network Places’ screen. Unfortunately, it asks me for a username and password and I’m not sure which one it wants. The screen rejects my Windows administrator login, my Mac administrator login, and the Homegroup password I was given when installing Windows.

I’ve also tried registering the same username and password on both machines but to no avail. can anyone help me out?

Regards,

Vincent
