Since the latest automatic Windows 10 update on my desctop PC, my Surface 2 (not pro) file manager cannot access its files. Clicking on Network shows the router, the tablet itself, network printer/scanner and the Desktop PC. The Properties shown for the Desktop look OK, but only the tablet itself shows in the submenu under Network in the LHS. A week ago it was OK. I have checked 'sharing' of C: drive, and 'Homegroup' on PC and can see nothing wrong. Ping works both ways. The PC claims it can see the C: drive of the Tablet but does not have permission to access it (though it is actually wide open). One user (nameA) on PC with passwordA, One user (firstname.lastname@example.org) on Tablet with passwordB Can anyone help?
