        bring up the properties of each network adapter to want
        to <strong>dis</strong>able the protocol for and clear
        the checkbox next to <strong>PPP over Ethernet Protocol</strong>
        in the listed components. <strong>BEWARE:</strong> If you
        accidentally disable the protocol for the network adapter
        you want to connect through, simply re-checking the
        checkbox, even if you do so immediately, may <strong>not</strong>
        be enough to make the protocol functional on that network
        adapter again. See <a href="#KnownIssue2">Known Issues</a>
        for a more detailed explanation and possible workarounds.</li>
</ul>

<ul>
    <li>The protocol is now fully functional, but you still need
        to create a dial-up connection to use it. See the next
        section for details.</li>

<h3><a name="Section3"><u>3.</u></a><u> Creating PPP over
Ethernet Dial-up Connections</u></h3>

<p>PPP over Ethernet dial-up connections can be most conveniently
created with the <strong>Dial-up Connection Setup </strong>application
provided with the protocol, which creates dial-up connections
with all the correct settings at the click of a button.</p>

<ul>
    <li>Click the <strong>Start</strong> button on the taskbar
        and select <strong>Run...</strong> to bring up the <strong>Run</strong>
        dialog box.</li>
</ul>

<ul>
    <li>Type <strong>RASPPPOE</strong> in the edit field and
        click the <strong>OK</strong> button to run the <strong>Dial-up
        Connection Setup</strong> application.</li>
</ul>

<ul>
    <li>If the application quits with an error message, follow
        the advice it gives.</li>
</ul>

<ul>
    <li>A dialog box comes up with a combo box labeled <strong>Query
        available PPP over Ethernet Services through Adapter:</strong>
        at the top. Select the network adapter your broadband
        modem is connected to from the list. If the protocol is
        only operating on one network adapter, the box will be
        grayed out as there is no choice to make.</li>
</ul>

<ul>
    <li>Generally, it is <strong>recommended</strong> that you
        create a connection for an <strong>adapter</strong>, not
        for a specific service, so that it continues to work even
        if your service provider changes the server or service
        name. To do this, simply click the <strong>Create a Dial-up
        Connection for the selected Adapter</strong> button now.
        Shortly afterwards, a shortcut to the new dial-up
        connection named <strong>Connection through </strong><em><strong>Adapter
        Name</strong></em> should show up on your desktop.</li>
</ul>

<ul>
    <li>If you want to create a connection for a <strong>specific
        service</strong>, click the <strong>Query Available
        Services</strong> button. The application will send out a
        query for offered services and display the result in the
        list view below. If an error message is displayed, see <a
        href="#Trouble3">Troubleshooting</a> for help. Otherwise,
        select the desired service and the button below will
        change to <strong>Create a Dial-up Connection for the
        selected Service</strong>. Click the button to create a
        connection for this service. Shortly afterwards, a
        shortcut to the new dial-up connection named <strong>Connection
        to </strong><em><strong>Service Name</strong></em><strong>
        at </strong><em><strong>Access Concentrator</strong></em>
        or <strong>Connection to </strong><em><strong>Access
        Concentrator</strong></em> (if the connection is for the
        default service) should show up on your desktop.</li>
</ul>

<ul>
    <li>After you have created the connection(s) you need, click
        the <strong>Exit</strong> button to quit the application.</li>
</ul>

<ul>
    <li>Double-click the desktop icon for the dial-up connection
        you created.</li>
</ul>

<ul>
    <li>In the <strong>Connect </strong><em><strong>Connection
        Name</strong></em> window, enter your user name and
        password if your service provider requires authentication.</li>
</ul>

<ul>
    <li>Click on the <strong>Dial</strong> button. If all goes
        well, you should be connected to the Internet almost
        instantly. If not, see <a href="#Trouble4">Troubleshooting</a>.</li>

<h3><a name="Section4"><u>4.</u></a><u> Removing the PPP over
Ethernet Protocol</u></h3>

<ul>
    <li><font color="#FF0000"><strong>WARNING:</strong></font>
        You are about to remove a driver. Since <strong>any</strong>
        driver removal poses a non-zero risk of crashing your
        operating system, you are advised to save your work and
        close all running applications before proceeding.</li>
</ul>

<ul>
    <li>Since you are about to remove a driver, you will need <strong>administrative
        privileges</strong> to perform the removal. If you are
        logged on to a user account, log off and log on to an
        account with administrative privileges before proceeding.</li>
</ul>

<ul>
    <li>If you are running <strong>Windows 2000</strong>, right-click
        the <strong>My Network Places</strong> icon on your
        desktop and select <strong>Properties</strong> to bring
        up the <strong>Network and Dial-up Connections</strong>
        window.</li>
</ul>

<ul>
    <li>If you are running <strong>Windows XP/2002</strong>,
        click the <strong>Start</strong> button, select <strong>Control
        Panel</strong>, then click <strong>Network and Internet
        Connections</strong> and then click the <strong>Network
        Connections</strong> control panel icon to bring up the <strong>Network
        Connections</strong> window.</li>
</ul>

<ul>
    <li>First, you may want to remove all dial-up connections you
        created for connecting through this protocol. To do so,
        right-click each of the dial-up connections you created
        for this protocol and select <strong>Delete</strong>. If
        you had created any shortcuts to these dial-up
        connections on your desktop, right-click them and select <strong>Delete</strong>
        as well.</li>
</ul>

<ul>
    <li>If you are running <strong>Windows 2000</strong>, you
        must first unbind the protocol from <strong>all</strong>
        network adapters to ensure that it is <strong>unloaded</strong>
        from memory. This step is <strong>not</strong> necessary
        if you are running <strong>Windows XP/2002</strong>. <font
        color="#FF0000"><strong>BEWARE:</strong></font> Do <strong>NOT</strong>
        do this if you currently have a <strong>RASPPPOE</strong>
        version <strong>prior to 0.95</strong> installed as these
        versions may <strong>CRASH</strong> the operating system
        when unbinding the protocol from the last network adapter.
        In that case, <strong>skip the next step</strong> and <strong>reboot</strong>
        after uninstalling the protocol to remove it from memory.</li>
</ul>

<ul>
    <li>To unbind the protocol from all network adapters, right
        click each <strong>Local Area Connection</strong>, select
        <strong>Properties</strong> and <strong>clear</strong>
        the checkbox next to <strong>PPP over Ethernet Protocol</strong>
        and close the properties dialog with the <strong>OK</strong>
        button. After clearing the last checkbox, the protocol is
        unloaded from memory</li>
</ul>

<ul>
    <li>Right-click <strong>any</strong> <strong>Local Area
        Connection</strong> and select <strong>Properties</strong>.
    </li>
</ul>

<ul>
    <li>In the list of components, select <strong>PPP over
        Ethernet Protocol</strong> and click <strong>Uninstall</strong>.</li>
</ul>

<ul>
    <li>A dialog box comes up asking you to confirm the removal.
        Make sure that you are really about to uninstall the <strong>PPP
        over Ethernet Protocol</strong> and click <strong>Yes</strong>.</li>
</ul>

<ul>
    <li>Back at the <strong>Local Area Connection Properties</strong>
        window, click <strong>Close</strong> to close the window.</li>
</ul>

<p><strong>Note:</strong> The protocol is <strong>not</strong>
completely removed from your machine at this point due to
shortcomings of <strong>Windows</strong>, which prohibit a
complete removal. The pieces that are left behind are <strong>not</strong>
harmful in any way, but if you want to get rid of every little
bit of this protocol, here is what's left behind: </p>

<ul>
    <li>If you are running <strong>Windows 2000</strong>, the
        protocol's <strong>Notify Object</strong>, named <strong>RASPPPOE.DLL</strong>,
        is left behind in your <strong>\WINNT\SYSTEM32</strong>
        directory. You can safely delete it at this point.
        Automatic deletion fails due to a bug in <strong>Windows
        2000</strong> (see <a href="#KnownIssue5">Known Issues</a>).
        In <strong>Windows XP/2002</strong>, this file is
        automatically deleted.</li>
</ul>

<ul>
    <li>In your <strong>\WINNT\INF</strong> directory, the
        protocol's <strong>INF</strong> file and its precompiled
        version is left behind, named <strong>oem#.inf</strong>
        and <strong>oem#.PNF</strong>, respectively. &quot;<strong>#</strong>&quot;
        stands for a number that varies with the number of third
        party drivers you installed on your machine. This means
        that you will have to identify the <strong>INF</strong>
        by loading each of your <strong>oem#.inf</strong> files
        into a text editor, e.g. <strong>NOTEPAD</strong>. The <strong>PPP
        over Ethernet Protocol</strong> <strong>INF</strong>
        identifies itself as such right in the second line of the
        file. Once you have identified the <strong>INF</strong>,
        delete it and the corresponding <strong>PNF</strong> file
        as well. This is not a bug, but Microsoft's design. These
        files cannot be removed automatically due to the varying
        name.</li>
</ul>

<ul>
    <li>Even if the protocol has been completely removed from
        hard disk and memory, the <strong>dial-up devices</strong>
        that were exposed by it will be shown in the properties
        of any dial-up connection until you <strong>reboot</strong>.
        This is a bug in <strong>Windows</strong> (see <a
        href="#KnownIssue4">Known Issues</a>).</li>
</ul>
