This is not to knock on SWAT, but I think if it's your first time you should configure the shares yourself. SWAT may be nice but you don't learn a damn thing. Such as the veto files issue I had when I installed the Office XP Pro CD on my server. Therefore I am going to show you a sample of my samba.conf. I removed all the comments from my server because I do not believe in them, in my httpd.conf however I do have comments to remember WTF I did. Notice on the veto files I took out the riched.dll because whatever is in the veto files, is hidden even though it is really there. It's a protection against some viruses.

Also make sure that you have permission to read and write to the files on the linux server. If samba was not configured properly in the beginning you may have odd permissions.
