Okay, I upgraded my system from FC3 to FC4 without a problem and everything loads fine with no errors in the system, smbd, and nmbd logs.
Now it gets wierd. I explore the shares from my XP machine, access them, change directories, and I cannot see the files that are in there nor do I have rights to rwx.
I went back to the directory on the FC4 system, the files are still assigned to the user group for the share. I even chmod'd a file to 777. Still, no files.
