Upgrade to 2.0.6 not working

[Gary.L.Smith at astrazeneca.com]

Hi All,

We have been running samba-1.9.18p10 beautifully for the past
year or so.  Finally decided to upgrade to samba-2.0.6 and am
having no luck.  We are using security=server such that the
users are using their NT login/password to authenticate.  When
I test the 2.0.6 installation with smbclient, I get the
"protocol negotiation failure" message.  Does anyone know what
this means?  I can't find anything in the documentation
regarding this.

root at berg/opt/samba(0)# ./bin/smbclient -L \\berg
doing parameter max log size = 50
doing parameter security = server
doing parameter password server = mainman.arcb.us.astra.com
doing parameter socket options = TCP_NODELAY

doing parameter wins server = 167.2.1.220
doing parameter dns proxy = no
pm_process() returned Yes

protocol negotiation failed

According to the log file for this client, there's some kind
of Internal Error happening:
