I STRONGLY suggest you stop trying to find alternative workarounds for retrieving your files, and concentrate only on investigating and resolving the original issue.
As I see it there is (was) nothing wrong with your server, it seems to be a network login rights issue.
While in windows explorer I right click my computer and select "Map Network Drive". In the window that pops up I entered "\\SME Server Name\Username" and assigned it to be drive X.
It may be that the credentials being passed from your workstation to your server are for a different user (ie the automatically logged in user), as you have now set up other workstations and the default user may actually be different. Even though you log in with a username and password they do not match up correctly. Usually only the logged in user can access their home folder.
Given that scenario, I think a workaround fix is appropriate and should work OK.
create an ibay
make your user name a member of that ibay
login to the server as root
copy all the folders and files from the users home folder to the new ibay
change the ownership of folders and files using a chown command so the files are accessible by anybody
map a drive to the ibay
access your files
It should be easy and straight forward.
If you want to go that way, I will provide the specific commands and steps so ask again here.
