When you build public facing sites with WSS or SharePoint, your users may be experiencing a message through IE asking them to run the Name ActiveX control.
This ActiveX control allows users to see presence information in SharePoint (when you go to a document library you can see if the author or editor is online at the time)
To get rid of this message on the browser, method 3 in this article fixes the issue (involves adding a js file to the server and modifying the master page)

But recently a colleague at livePoint (Luis) came up with a more elegant solution if you are dealing with externally hosted sites where you don't have access to the file system to install your js file.
His implementation was to add a javascript in the master page.
<script type="text/javascript">function ProcessImn(){}function ProcessImnMarkers(){} </script>
<script type="text/javascript">function ProcessImn(){}function ProcessImnMarkers(){}
</script>
This way when SharePoint loads the page it will use this function implementation and will override the one in the js file at the file system level.
