Exclamation red hat 9 logon error

I just installed Red Hat 9. Right after I logon, I get the following error:

Could not look up internet address for dhcp-82-86. This will prevent GNOME from operating correctly. It may be possible to correct this problem by adding dhcp-86-82 to the file etc/hosts.

[Log in Anyway] [Try Again]

Bypassing the error by hitting Log in Anyway continues the login, and I have no problems accessing the internet or anything else for that matter. I tried adding the line suggested to hosts, which didn't change anything. I have cable internet, and network prefs are set to use automatic dhcp configuration, so I'm not sure what is going on. When I log on, it also lists my account as 'dhcp-86-82@localhost.localhost. What's going on here?

Thanks in advance - any help or advice is greatly appreciated!

I also use cable modem and I have the same problem.
Linux will work correctly (including GNOME).

If I understand what is happening, your system is getting this address (dhcp-86-82) from your ISP and, unfortunately, when the system tries to resolve it, it will not find it, because dhcp-86-82 is not valid.

Long story short. I do not know how to correctly fix this issue. I ended up using one of my valid domain names as a hostname for my box. -> Problem fixed.
But not everyone as a domain name.

If you plan on using SendMail locally, every e-mail you send out on the internet will have a return-path: root@dhcp-86-82, which may caused some problems when some people, not all, try to reply.

If anyone knows how to fix this correctly, please post all suggestions.

i think it's trying to find that address on your local
machine, and your hostname isn't set up right, or
it's loopback entry doesn't exist in /etc/hosts, such
as localhost
or whatever yourhostname is.

In order to fix this just do the following.

hostname <makesoemthingupthat'scool>
vi /etc/sysconfig/network
Change your hostname to what you changed it to above
vi /etc/hosts

Since the dhcpwhatever your ISP issues you isn't a real hostname you can make your computer think it's a real hostname by adding it to /etc/hosts since your computer will search it first.

# Do not remove the following line, or various programs
# that require network functionality will fail. Shadow dell Crackwhore laptop Daemon daemon localhost Router

in the above example "Router" is what I named that machine as so I added that to hosts.

Once you name it whatever you want and add it to hosts you won't have this problem.
