when you change a dos attribute, within wireshark you should see
  Set Information Request, Path:\yourfile
  Set Information Response
packet pairs on the wire.
The passed "File Attributes" can be also viewed.

Haven't tried windows7 here, whether it uses a different approach.

Can you try on your server itself:
smbclient //localhost/test -U jim
... pw entry
smb: \> setmode yourfile +r
smb: \> setmode yourfile -r
