[Samba] Win98 Login Problem

[binc5]

** High Priority **

Hi
 
I am trying to login to a Samba share via win98, When I try get access
to a shared folder that is protected.  It prompts me for a password. 
the problem is that the username is already typed in and I can not
change it.  On winxP, when I get prompted I can put in the username and
password, and it works fine.
 
Please any help would be muchly appreciated.
 
Thanks
Steven
