Help with 404 error

[chasuav]

I have a situation and am in need of some help.

 

I have a Windows XP Pro SP 1 machine with Apache 2.2.6-win32-x86-no_ssl and PHP Version 5.2.5 installed.  I'm using Joomla 1.0.12 as my content management system and docman as my file manager. This server is used for a company's intranet via port 80.

 

The problem is, this machine is running under a default gateway of 192.1.1.1  Every machines that are under this default gateway has no problem accessing the intranet what so ever.  However, there are other machines from other branches that are running under a default gateway of 192.1.4.1 and 192.1.5.1 etc, When someone from these branches access the intranet (http://intranet) most of the time, they can get to the homepage just fine, but as soon as they click on any menu item from the navigation menu, they get a page not found error. 

 

This does not happen all the time but on a randomly pattern.  Sometimes, if they "Refresh" their browser a couple of times, the page will load just fine. 

 

Another note is, when someone from the branches gets a page not found error, users from the default gateway of 192.1.1.1 would also get the Page Not Found error.  But after about 10 seconds or so, users from the default gateway of 192.1.1.1 can access the intranet with no problem again.

 

I have checked Windows XP built in firewall and it is not enabled.

The httpd.config file is configured to listen to port 80

 

#Listen 12.34.56.78:80

Listen 80

 

The server name is configured to the apache server machines ip address

 

ServerName 192.1.1.120:80

 

I don't know what else to look for anymore, because the intranet is working fine for the main branch as long as other users from other branches don't access and get an error.  As soon as someone from the branches gets a Page Not Found error, this impact the main branch as well.  It is difficult to narrow down the problem because the problem does not occur constantly but on a randomly pattern only.

 

I don't believe the error is caused by joomla because the main branch is not getting any of these errors.  I almost certain that there is a firewall or switch issues, but I also don't know if there is any thing else in the httpd.config file that I should be looking for as well.

 

If need be, I can post the httpd:config file if this helps.

 

Anyway, any suggestions or advises on how to fix this is greatly appreciated.

Here is my httpd.config file.

 

#

# This is the main Apache HTTP server configuration file.  It contains the

# configuration directives that give the server its instructions.

# See <URL:http://httpd.apache.org/docs/2.2/> for detailed information.

# In particular, see

# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>

# for a discussion of each configuration directive.

#

# Do NOT simply read the instructions in here without understanding

# what they do.  They're here only as hints or reminders.  If you are unsure

# consult the online docs. You have been warned. 

#

# Configuration and logfile names: If the filenames you specify for many

# of the server's control files begin with "/" (or "drive:/" for Win32), the

# server will use that explicit path.  If the filenames do *not* begin

# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"

# with ServerRoot set to "D:/apache2" will be interpreted by the

# server as "D:/apache2/logs/foo.log".

#

# NOTE: Where filenames are specified, you must use forward slashes

# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").

# If a drive letter is omitted, the drive on which Apache.exe is located

# will be used by default.  It is recommended that you always supply

# an explicit drive letter in absolute paths, however, to avoid

# confusion.

#

 

# ThreadsPerChild: constant number of worker threads in the server process

# MaxRequestsPerChild: maximum  number of requests a server process serves

ThreadsPerChild 250

MaxRequestsPerChild  50

 

#

# ServerRoot: The top of the directory tree under which the server's

# configuration, error, and log files are kept.

#

# Do not add a slash at the end of the directory path.  If you point

# ServerRoot at a non-local disk, be sure to point the LockFile directive

# at a local disk.  If you wish to share the same ServerRoot for multiple

# httpd daemons, you will need to change at least LockFile and PidFile.

#

ServerRoot "D:/apache2"

 

#

# Listen: Allows you to bind Apache to specific IP addresses and/or

# ports, instead of the default. See also the <VirtualHost>

# directive.

#

# Change this to Listen on specific IP addresses as shown below to

# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)

#

#Listen 192.1.1.120:80

Listen 80

# 'Main' server configuration

# The directives in this section set up the values used by the 'main'

# server, which responds to any requests that aren't handled by a

# <VirtualHost> definition.  These values also provide defaults for

#

# ServerName gives the name and port that the server uses to identify itself.

    # If you include a trailing / on /webpath then the server will

#

# Apache parses all CGI scripts for the shebang line by default.

# This comment line, the first line of the script, consists of the symbols

# pound (#) and exclamation (!) followed by the path of the program that

# can execute this specific script.  For a perl script, with perl.exe in

# the C:\Program Files\Perl directory, the shebang line should be:

 

  #!c:/program files/perl/perl

 

# Note you _must_not_ indent the actual shebang line, and it must be the

# first line of the file.  Of course, CGI processing must be enabled by

# the appropriate ScriptAlias or Options ExecCGI directives for the files

# or directory in question.

#

# However, Apache on Windows allows either the Unix behavior above, or can

# use the Registry to match files by extention.  The command to execute

# a file of this type is retrieved from the registry by the same method as

# the Windows Explorer would use to handle double-clicking on a file.

# These script actions can be configured from the Windows Explorer View menu,

# 'Folder Options', and reviewing the 'File Types' tab.  Clicking the Edit

# button allows you to modify the Actions, of which Apache 1.3 attempts to

# perform the 'Open' Action, and failing that it will try the shebang line.

# This behavior is subject to change in Apache release 2.0.

#

# Each mechanism has it's own specific security weaknesses, from the means

# to run a program you didn't intend the website owner to invoke, and the

# best method is a matter of great debate.

#

# To enable the this Windows specific behavior (and therefore -disable- the

# equivilant Unix behavior), uncomment the following directive:

#

#ScriptInterpreterSource registry

#

# The directive above can be placed in individual <Directory> blocks or the

# .htaccess file, with either the 'registry' (Windows behavior) or 'script'

# (Unix behavior) option, and will override this server default option.

#

 

#

# DefaultType: the default MIME type the server will use for a document

# if it cannot otherwise determine one, such as from filename extensions.

# If your server contains mostly text or HTML documents, "text/plain" is

# a good value.  If most of your content is binary, such as applications

# or images, you may want to use "application/octet-stream" instead to

# keep browsers from trying to display binary files as though they are

# text.

    # To use CGI scripts outside of ScriptAliased directories:
