DHCP connection on Tangerine iBook

[Marc Bosch]

Fellow listers,

My daughter has not been able to connect to her university's network 
with her tangerine 300mhz iBook running OS9.2.2.

Other iBooks, running OSX, can connect, and it is a very PC-dominant 
school.
She has had some tech support for the basic TCP/IP settings, but they 
have not resolved it.  This "should" be a no-brainer.

Her TCP/IP control panel is configured for DHCP and ethernet, and they 
have given her appropriate IP addresses to try, even though that should 
not be necessary for DHCP. She has tried the DHCP manual settings as 
well.

She tried and verified a host of "possible" causes: ethernet cord, wall 
plug, trashed TCP/IP preferences, removed MacTCP DNR file, rebuilt 
desktop, set Apple Talk CP to ethernet, used Apple Knowledge Base docs 
on this topic, and other.

Two Questions:
1.  Is it possible the school's network protocols have been set to 
accept "only" Windoze OS and Mac OSX machines?
2.  Are there other settings or configs that we are overlooking?

Any help will be appreciated. TIA.

PS. Installing OSX is an option we are pursuing.  Should have done that 
before.....
Thanks!
Marc
