[Samba] From Samba 2.2.3 to Samba 3.0

[Frédéric Pierron]

Hello,

I used Samba 2.2.3 on a Linux Red Hat 7.3 platform (server and client).
I've just moved to Samba 3.0 by updating the rpm with the binary package
Samba 3.0 for Red Hat 7.3.
My smb.conf wasn't modified during the upgrade of Samba (no encrypt
passwd).
Then, Samba doesn't work anymore. I can launch smbd but I can't connect
by smbclient from any client (even from the server).
Are there any differences between 2.2.3 and 3.0 that can explain this ?
What should I do to recover Samba ?

Thanks for your help
