Windows 10 Network sharing issue

I am running a peer to peer win 10 network. I have one of my computers (A) that can access the other (B) through explorer, but when I try to save a new doc or open one through the dialogue box to that computer (B) I cannot find it in my network folder. What am I missing? I can open any file off of (B) from (A) through an existing shortcut and all of my permissions appear good.


Thank you,
John
