Apache/Netscape unable to find server.

[ktb <xyf@inetnebr.com>]

I'm hoping someone can help me out here.  I have no desire at this time
to set up a web server for myself but I am doing some volunteer work for
and archeology agency (writing a search program to work through a
browser).  I'm suppose to meet with them on Monday and I can't test my
script.  I had Apache installed on my Debian system and was using it to
test a Perl script I was working on.  I had to reinstall and when I
installed Apache this time I get this Netscape error when I try to run
my search program,

Netscape is unable to locate the server www.xyf.com
Please check the server name and try again.

I have everything set up as I did before.  My html
form is in /var/www and the program is in /usr/lib/cgi-bin.  Last time I
edited,

/etc/apache/httpd.conf
/etc/apache/httpd.conf.0

by adding "ServerName www.xyf.com" and everything
worked fine for me. The page in /var/www loads just fine but when I use
this form to search a file the Netscape error I listed above pops up.
Does anyone know how I can fix this?  I looked in,
  
/var/log/apache/error.log

and nothing was there but Apache shutting down and
starting.    
Thanks,
kent
