Can not access Windows XP computer over the network?

You could ping a Windows XP computer. But can not access using Network Neighborhood or my network places or by using UNC path. You keep getting "Network path not found" error whenever you use the computer name. Here is the solution.

Open Windows Explorer, Click Tools, Folder Options, View and deselect or uncheck the very last line option "Use simple file sharing (Recommended)".

You are done.
