Sharing mac volume with Samba


I am trying to get my mac volume shared to my windows box for 3 days now... with no luck.

Installed Samba X2.2.1a, attempted to configure it with SSCT 2.1.. but I can't log in from my w2k box, for some reason. If I try a 'share' security type, I can browse the shares, but can't access them.

I think the problem is that samba doesn't recognise my login name (the same as my username for my mac)... running the following on the command line:

sudo smbpasswd [username]

and changing the password gives me the following error:

Failed to find entry for user [username].
Failed to modify password entry for user [username]

Any advice?

PS. My OS X version is 10.1.
