Windows Network does not show computers, but I have a batch file that will load them and log in. I have used Credential Manager to set up accounts and if I try to log into a computer from "Run", it still requests a password. Both these issues are working on Windows 8 with no problem; I have four computers set up as Network Locations with one being XP. The problem computer is a tablet running 10 which I can reach with the other three.
