Did you check both Share and File Permission rights? You need both to be setup properly to gain access.
Setup user accounts on the system to use, when mapping the share use this format to authenticate "net use [{DeviceName | *}] [\\ComputerName\ShareName[\volume]] [/user:[DomainName\]UserName]". So would look like "net use Z: \\PCName\MyShare /user😛Cname\MyUserName", after you hit enter it will ask you for the password.
The DomainName would be the name of the computer with the share, the UserName will be the user on the remote system you setup.
Make sure that use has rights to the share AND the file permission rights.
When trying the Net Use command on the XP machine, I get 'System error 85 has occurred' The local device name is already in use. Like I said, there's full read write permissions in effect for all users on the Win7's C-Drive.
Does that include the Share rights as well as the filders/files? That error just means you already have that drive mapped, pick another drive letter.
Having no passwords is a bit trickier to use with shares across different operating systems, in some cases you need to setup a user with a password.
