Jose,
This sounds like a firewall issue. A misconfigured firewall could block
incoming HTTP, DNS, DHCP request. Red Hat comes with an easy to use firewall
that has three security settings, high, medium and none. Go to Main Menu ->
System Settings ->Security Level. As a troubleshooting step, try changing
the security setting from high/medium to none. Click OK and then test your
client. If your client now works, you will need to customize your firewall
security so it allows incoming, WWW, SSH, DHCP. If you configured Apache web
server to use SSL, you will need to add 443/tcp and 443/udp to the Allow
incoming services.
Can anyone answer how to add addition services like 443/tcp, 443/udp to the
Allow Incoming section of Red Hat Security Level program. I realize you can
probably do this using iptables method, but I believe there is an easier
way. I know during the Red Hat installation, you have the option of adding
addition services to the Security level's allow incoming list of services.

Just a thought, it might be a client problem.
Can you ping the NetReg Server?
Do you have a BHO (Browser Helper Object) on your machine? (aka spyware,
scumware, adware) BHO have a commen thread that they redirect all of their
traffic thru an external server. If that server is not reachable, then it
won't display webpages.
Try telneting to the Netreg server webprocess
>From your client machine's command prompt type:
C:\> telnet netreg.yourdomain.edu 80
Where netreg.yourdomain.edu is your netreg server, and 80 is the port your
connecting on, (your webserver port)
When you get the blank screen, type GET (all caps) you should see the HTML
from your default page, and the connection close.
If you get that, the Netreg server is working.

I am able to get an ip address (unknown clients) from the DHCP but I am not
able to browse the web server.
Any suggestions!!!
