I have 3 Win 7 computers network together in a joined homegroup. PC A host the homegroup. PC B & C join the homegroup. Each PC has no problem accessing each other file sharing. Until recently, I renamed PC C to D. The problem is now PC B has problem accessing PC D, but PC D can access to PC B. When PC B try to access PC D, it will popup a dialog box requesting entering username & password. However, PC A still can access to PC D.
Why is that after renaming, that PC cannot be accessed by other PC? How can I fix it?
