NT 4.0 SP 3 problems serving up from a SUN Sparc 10 running Solar is 2.5

[Thompson, Martin]

I am having problems logging into my Sparcstation as user  "thompsma" even
though user thompsma is defined in /etc/passwd
and /usr/local/samba/private/smbpasswd using the smbpasswd command. I get
the following message:

"The account is not authorized to login from this station"...

I am attempting to login from CRW048 which is IP 132.225.34.139.

Here is my smb.conf file...

[global]
   printing = bsd
   printcap name = /etc/printcap
   load printers = yes
   guest account = pcguest
   workgroup = AECL
   hosts allow = 132.225.34.139 132.225.34.41 127.
;   remote browse sync = 132.225.34. 
;   remote announce = 132.225.34.
[homes]
   comment = Home Directories
   browseable = no 
   read only = yes
   create mode = 0750

[printers]
   comment = All Printers
   browseable = no
   printable = yes
   public = no
   writable = no
   create mode = 0700

; you might also want this one, notice that it is read only so as not to
give
; people without an account write access. 
;
 [tmp]
   comment = Temporary file space
   path = /tmp
   read only = yes
   public = yes

[MTHOME]
   comment = MARTIN THOMPSON
   path = /dat66/accounts/thompsma
   public = no
   writable = yes
   printable = no

Any ideas would be most appreciated...
