Thanks again guys, it's great to have so many willing to help.

I think my syntax and usage is correct but my NAS is the issue.

Thanks to Kenny on the MorphOS team emails, he also has a NAS from QNAP and found that the latest Samba security updates caused the same issues for him.

Hopefully the manufacturer can provide suitable firmware to me.

Until then I would be willing to help test any newer release for SMBFS or SMB=Handler.

Thanks again!

Matt
