What version of samba was the previous DC running?    I would run 
"testparm -v" and see which versions of NTLM are enabled. I am pretty 
sure you need "ntlm auth = Yes."   Also, NT4 might not support some of 
the signing options.  By default "server signing = No" is set - at least 
on my machines.   However I don't have an NT4 server so I can't say for 
sure if this helps.   Presumably you have at least SP4 installed on your 
NT4 machine?

I would also guess that Samba 3.4 was not heavily tested against with 
NT4 clients.
