My hosts file now has this line in it:

127.0.0.1   localhost localhost.localdomain localhost4 
localhost4.localdomain4 member1.ts.mystuff.com member1

I seemed to recall that each line in hosts could only have 4 names, but 
left the default installed names on the localhost line.

I stopped and restarted smbd, nmbd, and winbindd to no avail. I then 
tried rejoining as a member with no benefits.
