[Samba] Samba 3.5.10 RHEL6 vs Win7 pro Koan

[WSIS Tech]

My RHEL6 is running Samba Server Version 3.5.10-125.el6
My laptop is Win7 Pro Service Pack 1

My Windows Explorer CANNOT see the Samba..
But in a DOS window ..
1) net view
\\BLACK6               Samba Server Version 3.5.10-125.el6
\\GHD-M7
\\PENTIUMD             HP Pentium D On top shelf
The command completed successfully.

2) C:\Users\ghd>net view \\Black6
System error 53 has occurred.

The network path was not found.


3) C:\Users\ghd>net view \\192.168.0.201
System error 5 has occurred.

Access is denied.

4)  C:\Users\ghd>net use x: \\Black6\ghd
Enter the user name for 'Black6': ghd
Enter the password for Black6:
The command completed successfully.

The mapped drive is visible and I can read files..
(the user ghd is a user on all the machines, with the same password
AND a samba user)

I can read files from the share..  /home/ghd .. on RHEL6 ..
But if I create a file from win7 to the share, I get a "File too large"
error on attempting to rename the file.

Obviously, I'm miss-configured.   Can someone please help get this
sorted out?
