The hosts file doesn't set your hostname, it just associates DNS names
and IP addresses. Elsewhere, the hostname is set.

Now my ISP's DNS was down and today they gave me a new DNS address.
This time I used again the graphical tool to set the new DNS address.
Reactivated the network card. What happened was my hostname was
changed from current name to previous one without my knowledge. I
didn't notice the problem till all other windows machines were unable
to reach the webpage hosted on it.

Sounds like yet another issue. Those other PCs don't use its hosts file
to find it, they use their own or a DNS server. You can blank out your
hosts file, and it won't affect other PCs from finding it.

What do you mean by they gave you a new "DNS address", though? They
changed your hostname, IP address, told you to use different IP
addresses to access their DNS servers at, or something else?

I had to reedit the /etc/hosts file to change my hostname and
reactivate the network card to fix the problem.

This made me think that "system-config-network" doesn't rely on the
/etc/hosts files. It must have its own backup file which get rewritten
in /etc/hosts file after some modification

# locate hosts |grep /etc
/etc/hosts
/etc/sysconfig/networking/profiles/default/hosts
...[snip]...

It's been a while since I played with dialup, but I think the idea was,
during dialup to use one as a template, and modify the /etc/hosts while
connected, then put it back as it was after disconnection. I can
remember that malarkey with the /etc/resolv.conf file, but I can't
really remember what changes were made to hosts files.

If you edit, and restart the network, out of sequence, you might have a
bit of confusion.
