Try disconnecting the mapping

Restart the computer

Remap the share

Thomas GrassiSystems AdministratorCommented:
Have you checked the share and ntfs permissions

Compare with one who works

Try creating a new share see if that helps

what is ntfs permission? can you explain more in detail
Thomas GrassiSystems AdministratorCommented:
When you click on the drive or folder and select properties the tab Security you will see the File permissions (NTFS) also in the same properties you will see the tab for Sharing then select advanced sharing you will find the Sharing Permissions there

They are two different types of permissions required when sharing files folders etc.
