[Samba] Samba fails

[McGranahan, Jamen]

We are running Samba 3.5.8 on a Solaris 10 box and created several shares on our server so that people can access certain files/folders via the Active Directory (so we are also using winbindd). This worked well for a couple of years until recently - now, we are not able to access any of our shares. When we try, samba crashes (though nmbd & winbind do not). I've gone through several tests:

testparm -> everything is fine here

wbinfo -u, wbinfo -g, getent passwd USERID, getent group GROUPID -> all are successful

When I try smbclient, connecting to the server itself, I get "tree connect failed: NT_STATUS_CONNECTION_INVALID". On the Samba listserv, there was a post just like this on 8/3/2011, but no solution was offered (other than please send a debug level 10 log - don't know if this ever happened). I tried the recommendation on this page - http://www.unixresources.net/linux/lf/56/archive/00/00/05/78/57864.html - changing "valid users" to just "users", and got the same result. I'm not really sure what else to try, but I sure would appreciate any suggestions or recommendations. Thank you!
