Cant file share vista and mac (10.6)

[thegeezer3]

Ive been trying to set this up for 6 hours now and no luck. Ive followed tens of tutorials as well.

In MBP I have

• 
  set file sharing to on
  set SMB to on and checked my username directly below.
  designated my user directory to be shared as read and write,
  set the firewall to allow smb
  set my workgroup to WORKGROUP under WINS for airport (i connect via wifi)

In Vista I have

• 
  turned off all my security - virus, defender, firewall
  set file sharing on
  shared my documents folder
  set the registration key LmCompatibilityLevel to 1

Now in the mbp nothing shows up in the finder under shared. I tried connecting to my vista ip address via go => connect and nothing.

In Vista in networks my macbook shows up but when i try to click open it up it hangs and complains the name might not be correctly set.

I cant ping either whether its mac => PC or PC => mac.

Can anyone help
