Hello ,I think you will get proper solution from above 2 post but there is another problem is seeing shared folder on network then it is most likely an issue with a particular service being turned off. Then you can solved it by going to START>Run>services.msc and then made sure that services involving networking were not disabled and set to automatic.
Windows Registry Editor Version 5.00
Code:
; DISABLE SHARING
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Network]
"NoFileSharing"=dword:00000001
"NoPrintSharing"=dword:00000001
