Since you are using Windows XP, make sure that you have Simple File Sharing turned off. This can be accomplished by going to any explorer window, pressing Tools, and going to the last option "Folder Options." Once there, go to the "View" tab and scroll until you see something that says Simple File Sharing, and make sure you select "Do Not use Simple File Sharing."

After you have done this, try reconnecting to your SMB server with the proper credentials (SERVERNAME\username for the username, and then whatever password you set).

Good Luck!
