log4net not working on other machines

Question

I created a web service project that uses Log4Net to log to the event viewer and optionally to a .log file. Everything works great on my machine, when I try to deploy it on another machine it won't even log to the text file or the event viewer. The fact that it's not even writing to the text file makes me think it's not able to find the log4net.dll or something to that effect?

I'm also receiving an error message when it hits the noted line below in my global.asax:

log4net:ERROR XmlConfigurator: Failed to find configuration section 'log4net' in the application's .config file. Check your .config file for the and elements. The configuration section should look like:

section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /

I'm stumped, I have no idea why this isn't working, help!

Ran an exe compiled from the following code that adds the source to the eventlog in Windows, like I said, works fine on my machine:

Option Explicit On
Option Strict On

Imports System
Imports System.Diagnostics
Imports System.Threading

Module Module1

Sub Main()

    If Not EventLog.SourceExists("LendingService") Then
                    EventLog.CreateEventSource("LendingService", "Application")
        Console.WriteLine("Creating Event Source: LendingService")
    Else
        Console.WriteLine("LendingService events already defined to this system.")
    End If

      End Sub

End Module

You are looking for you configuration in your app.config file. To change this you can use:

// Configure log4net using the .log4net file
[assembly: log4net.Config.XmlConfigurator(ConfigFileExtension="log4net",Watch=true)]
// This will cause log4net to look for a configuration file
// called TestApp.exe.log4net in the application base
// directory (i.e. the directory containing TestApp.exe)
// The config file will be watched for changes.

or

log4net.Config.XmlConfigurator(ConfigFileExtension="log4net",Watch=true)]

as reference:

// Configure log4net using the .config file
[assembly: log4net.Config.XmlConfigurator(Watch=true)]
// This will cause log4net to look for a configuration file
// called TestApp.exe.config in the application base
// directory (i.e. the directory containing TestApp.exe)
// The config file will be watched for changes.
