All OSX releases prior to yosemite have networked with my windows computers, on a home network, flawlessly. Yosemite seems to have broken that. On one Mac, one of the two computers that my 10.9 connected to previously can't be found, even though the name is there. On my second Mac, it can't find either of the two windows computers I have. Nothing I have tried is working. The names of the windows computers hasn't changed. Yet one Mac computer can connect to one of the other window computers. When I try telling the other mac to use that name, it can't find it. HELP???
