I was able to get the connection to the NAS working again by adding the following line to the [global] section of /etc/samba/smb.conf

client min protocol = NT1

I am not sure if I have added any security problems, but at least I can access my NAS now. So you know I have a Buffalo LinkStation LS-QL.

I am not the only person with this problem. I have come across several posts about this subject. I am trying to get the others to come to this report and add their input.
