[dba-Tech] Network Password

Dear Lists:
 
Time to figure this out.  I am trying to get my laptop - which I only use
for travel - to talk to my primary box so I can upload stuff I need to take
with me.  I've been working around this for a long time by copying to my
external HD and plugging that into the LT.  But that's soooo unprofessional.
 
When I try to connect to the main box from the LT or from the LT to the main
box I get a dialog box asking me to Enter Network User Name and Password but
I have no idea what this could be.  Main box does not have a login, just
fires right up - LT has a login - user name and password, but that does not
work as credentials on either box.
 
Any ideas how to find the Network User Name and Password?
