KB IssueWhen sharing across the network with Windows 7, you may get an error telling you that it is not accessible or that you do not have permission.
Issue DetailsCreating network shares has always been rather easy to do, but now that Windows 7 has come along, we are faced with some more challenges in our goal to create that share across all computers in our network.

The following error is just one of the few that you may receive when trying to access the Windows 7 share from another computer.



\\win7pc\shared folder 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.
Recreate Issue
In Windows 7, without the proper permissions set for the share, you will not be able to access it via the Network.
Microsoft has tightened up its security for shares so that you have to go that extra step in order to allow someone access to the share. This, in turn, may cause a person to avoid performing the required steps to share their files.
This is a good thing, the reason:
Sharing can be a bad idea if you do not properly set permissions and allow the wrong person to access your files.
