samba - Mar 1998 - NT Primary Controller problems.

I have Samba running on a Linux platform and I used to have my NT
V4.0 Primary Domain Controller successfully mounting Samba shares.
	Acouple of days ago, I installed NT V4.0 service Pak3 and I.E.
V4.0 to my Primary Domain Controller. Everytime I try to connect to a
Samba share on my NT machine, I now get this error: "The Account is not
authorized to login from this station" .
	Has anyone seen these before? Does anyone know what I need to do
to solve this?

Best Regards,
