I am not sure if you are using Samba for DC duties as you don't
explicitly say, but I can give you some general things to be aware of:
-Windows NT < SP3 and Windows 95 clients have issues in native 2003
domains due to SMB packet signing (if that's what you are moving to).
You can address that
Greetings folks,
I'm currently using the latest samba 3.x versions but my servers
are in an NT4 domain which has a trust relationship with an AD
in mixed mode. This has worked flawlessly for the past few years
(I started with samba 2.x series).
I am heavily considering getting rid of the domain
