[rhn-users] Hostname change not getting reflected on redhat network profile for system

Bingo. The client updates the "Hostname:" part of it's System Details 
page with the results of a reverse lookup. If DNS returns a bogus name, 
the bogus name will get stored in the profile. I believe you could force 
it to show the hostname you want by adding the info to your /etc/hosts, 
but your best bet is probably just to change the DNS info.

Note the difference between the "profile name" and the "hostname" The 
profile name is arbitrary and can be reset manually. The "Hostname:" 
value in the System Details RHN web page is always going to show the 
results of a query on the system's IP address ("unknown" if the query 
fails). Also, you don't need to re-register your system just to change 
the info on the System Details page. The "up2date --hardware" command 
will update this information for you.
