Problems connecting to Samba Server

[Villagomez, Sigrid H]

I installed Samba (bbf format) on AIX 4.3.2 for the first time.  The client
is NT 4.0(SP 5).

I am able to connect to the tmp share name.  Also, after a few attempts I
was able to connect to another share name that requires a password.  When I
powered on my PC the next day, I was asked to enter the network password, I
did.  I typed the username and password but it was rejected.  Next I tried
connecting using the command line.  It failed.  This time, however, I got a
message, "System error 86 has ocurred"  "The specified network password is
not correct." 
I have rebuilt the samba password file (smbpasswd.sh) from my /etc/passwd to
no avail.  
The net command that I am using from NT is, NET USE X: \\ServerName\ShareDir
/USER:username, also I tried, NET USE X: \\ServerName\ShareDir password
/USER:username.  Nothing seems to work. 
net view \\ServerName works OK.
nmblookup works OK.
netbios-ssn is in Listen state.
I can connect directly from the AIX system using, smbclient
//ServerName/ShareDir -U username.
Where did I screw up?

Any help will be greatly appreciated,

Sig
