I am using Windows 7 on all my PCs and I have all PC networked & join as homegroup. Most of the time file sharing and accessing other PC works fine. But it is also frequently that sometime having trouble to access other PC even know that PC is show in Network. When double click on that PC icon, windows will popup error "Windows cannot access \NETPC". This cost us huge inconvenient to access files from other PC.
Why is it having trouble to access sometimes? How can I solve it?
Thank you.
