-- You'll see a little house that says Network next to it. If you have not already done this (and why are you reading this if you have?), it will probably say Work Network underneath that. Whatever it says, click it. You will be presented with three options. I tried Home and Work. Home is the one that worked best. -- It will show you another page that lets you select your libraries. I don't have or want any of the things it shows so I clicked them Off. (In an early iteration, I selected Documents. It did no good.) Then click Finish. --It will offer you a random password. I never found a use for it and it is easy to change (Network and Sharing Center->Choose homegroup and sharing options (middle bottom)->change the password. But, as I said, I never found a place where I could type it. -- Also, since I am working on a virtual machine, I do not keep a password on my Windows login. When I tried to access the new server from my Macintosh with my userId and (blank) password, it said the password had expired. To workaround this, I went to Network and Sharing Center->Change advanced sharing settings (left column - great UI!, not) and clicked "Turn of password protected sharing". If you read carefully, this allows guest access to the shared folder. Since I am, technically, visible on my office network, I also clicked "Turn off network discovery" to reduce my visibility. 3) Back on the folder you want to share, right-click and, about a third of the way down is a selection called Sharing. Do this and choose, homegroup (read/write). 4) On that same tired folder, right-click->properties->Security. Click Edit, then Add. There you will see a place where you can Enter an Object Name. Enter "everyone" (without the quotes). Click Check Names. It should capitalize the word. Then OK. You will see the list of "Group or user names." Make suer 'everyone' is selected and, in the panel below, choose Full Control. Then OK to get out of that property panel.
