How do I diagnose this?

[bruce.labitt at autoliv.com]

Recently I changed employment.  (Our group was bought.)  It appears that 
the new network is configured quite differently than at my previous 
employer.  Naturally, stuff has broken.   Right now I am trying to figure 
out why yum and wget (http and ftp) fail.  I think it may be because the 
programs would need to login to the network before being allowed access. 

From my observations, this past week, I believe this is a windows centric 
organization.  I have an active directory login.  When I first used my 
browser in linux, it challenged me.  I provided the correct credentials 
and was able to access the net.

What should I do to try to figure this out?  Do I need to use ntlmaps, 
which is a python program?

My local IT person linux experience is not recent, however, he seems to be 
quite willing to learn.  I would like to know what to ask for, or at the 
very least how to write up a help ticket.  It would be fun to figure this 
out with the list's collective help, however, which is why I am asking...
