Have you actually went through the process of sharing a folder on all PCs involved??
...absolutely; 1st: they were communicating "before" w/o trouble; 2nd: I have tried 'ALL' of the many suggestions, renamed the network to
myNAME, signed out-and-in to make it stick; automatic activation etc etc -- right now I cannot even 'see' any of the other PC.
I erased those 'media-network' files - they gave me NO access either and I did not want to share just media.
Could it be that MS is trying to force me to both PC owners have an MS / outlook / live account?! that would make sense in that MS too is trying to hook up real user data (phone etc ++) to the respective hardware+win10 constellation.
Honest? I cannot believe that not more people have (had) that very same problem; I mean, update took over closing my delicate open files NO MATTER WHAT - but should
never touch what had worked before!!
Thanks to all involved an helping; a great weekend to y'all
