I've been using windows shares for years without issues. I agree back in vista pre-SP1 days it may have been a bit psycho but since then it is fine.
So long as your network is set to 'private', allow network discovery and sharing (on each computer on the network), then any folder you share should work just fine.
As long as you have done it before & know what your doing, the sure>
But , its still a buggy mess, as witnessed by the OP
How may PC-PC sharing's have you set up ?
Just wait till you come across the bug when a PC cannot access the share, no mater what.
Its a bug, theres been a few threads in geekzone about it. Requires Net Use batch file , running on startup to solve the issue
Such a nasty bug, that even running "net use" from within Win wont work in that case(only works if run on Win startup)
Then theres the bug (bad design) with Domain connected PC's trying to access shares on Non domain PC's requiring a login/pass
Yes, its a buggy , overly complex mess. In now way is PC-PC sharing suitable for the Average user to setup .
Sometimes it just works, other times it takes alot of effort to make it work.
At least the master browser issue from years back seems to be a thing of the past :-)
