I have three computers in my homegroup. While I have been successful in sharing folders between two, am unable to do with third one. KR-PC is able to connect with RK-PC. but RK-PC is not able to connect to NUPC-PC This snap shot is from RK-PC. When I put in the homegroup password from NUPC-PC, it says invalid username or bad password. What should be the username here ? thanks.
