Windows NT 4.0 SP3

[leach at pcs1.hac.com]

I have Samba 1.9.17p2 and it works great on NT4.0 SP2

When I update to NT4.0SP3, my Samba connection gives me the following message:

	The account is not authorized to login from this station.

Did something change? 
Maybe NT4.0 SP3 uses a smb.conf option that wasn't used before?

I've installed the package version from the Solaris 2.5 web site. 
I'm actually running Solaris 2.5.1
