Using samba in ECS/OS/2 check smb.conf file, make sure workgroup name is the same as Windows.
"smb.conf file found in mptn\etc\samba"
Must be using samba of course.Make sure that something is shared in smb.conf
eg:
[C]
comment = Drive C: (JFS)
path = C:/
read only = No
guest ok = Yes
hide files = /*. SF/root/
Start the samba serviceWindows 7 setup.Create a folder/directory eg I use a folder called "Public". eg: c:\Public
Right click on your new or old folder you wish to share.
Select share with specific people.
Choose "everybody" and allow read and write permissions.
Right click on the same folder and select properties/sharing and select advanced sharing.
select "Share this folder"
Apply,ok, close window.
Now go to control panel and find network and sharing center under advanced sharing settings.
Under both "home or work" and "Public"turn on network discovery.
turn on file and printer sharing
turn on sharing so anyone with network access can read and write files in the Public folders
Under password protected sharing turn off password protected sharing.
I only share one folder and only put what needs to be shared, and I turn off the default share on the
folder called Users.
So at the end of this you should be able to share a folder
with NO password.
I share all my drives on ECS2.2 and one folder on each windows machine with no problems.
Use these notes at your own risk!!! 
Hope this helps and happy networking.
