You will have to select a directory to share out.
I normally create a directory put it right under the /home
When an unknown user accesses this directory they
are mapped to a user called
nobody, I personally
transfer ownership of the dir. to nobody (see permissions),
but that's not necessary. Keep in mind that the user
nobody
has to have read/write rights.
Now we will use this share in configuration.
Your workgroup and domain controller settings will differ from mine.
The workgroup should match the name of your Windows Workgroup
and in your case is will most certainly be a domain controller.
I may even have to come back and adjust.
