Changing Computer's Name

[Robert roehner]

Yesterday when I upgraded my iMac to Jaguar, dummy me gave the iMac 
the same name as our eMac. Is these any way to change the name of one 
of those computers?  It may be silly, but it does get confusing when 
I try to access one computers HD from the other by choosing Connect 
to Server from under the Go menu and the same names appear. Thanks in 
Advance.
