Another Linux Blag

I share folders with samba fine, on other computers running linux they can see it fine, when I tried to access via a computer with windows xp it came up with a password prompt, I put it my username and password however it rejected it.

Must remember in terminal to:

sudo smbpasswd -a <user>

which will then prompt:

[Enter your password] (as it says)

New SMB Password: (enter the password which you will use to access from xp machines)
Re-Type SMB Password: (as it says)

that <user> and password combination should now work in the password prompt in xp and let you login.
