question: i am trying to share and open my folder from one windows 7 computer to another windows 7 laptop but it keeps giving me error when i go to the network section:

OPEN FOLDER:

you might not have permission to use this network resource

\\MYLAPTOP is not accessible. you might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.

logon failure: the user has not been grated the requested logon type at this computer


so today we are going to address this question from gary: try doing this if you are also getting this error:

go to your control panel then click on Network and Sharing Center

then click on the network you are: (home network)
02p-8331-network-sharing.gif

then select 'home network'
02p-8331-home-network.gif

now select: view or change homegroup settings:
02p-8331-home-network-change.gif

finally clikc on join now:
02p-156298-home-network-join.gif


be sure to also do the same for the other computer. you will be ask for a password, so be sure to write it down:
02p-8331-home-network-password.gif

after you have completed these steps, you will get a confirmation:
02p-8331-home-network-joined.gif


also, be sure you have setup the the network sharing settings correctly: this is how i have mine setup:
02p-8331-home-network-sharing.gif


shortcut:
if you want the path: Control Panel\\All Control Panel Items\\HomeGroup

hope that helps
