I was wondering if someone could tell me what is causing these errors?

Do a forum search here on "SPNEGO", and you'll find the answer...

It's a Samba thing...

Any harm in turning off samba share? under usb Application->Network Place (Samba) Share / Cloud Disk as far as I can tell I don't use samba or even sure why I would need it? USB hard drive to router? If so ill never use that

It's for USB Shared Disk support - if you don't need it, you can turn it off...
