UPDATE: Are you using SharePoint 2010? See my newer post about the name ActiveX message in SharePoint 2010.
Have you seen this message on public facing SharePoint sites:
The Web site wants to run the following add-on: ‘Name ActiveX Control’ from ‘Microsoft Corporation’. If you trust the Web site and the add-on and want to allow it to run, click here…
For an example of one (at least until they fix it), check out:
There are quite a few nice examples of internet facing SharePoint 2007 sites on the interwebs these days, however many of them seem to be plagued by this minor annoyance that seems to have slipped through the Microsoft cracks. The problem is compounded by the fact that most developers won’t even notice the issue until their portal is available to internet users. This is due to the fact that the problem is seen only in Internet Explorer 7 and only when you are visiting a WSS v3 website that is NOT in your trusted site list for IE. You will not see the message most of the time in your local environment because, by default IE knows you are visiting an intranet site and auto-magically puts the site in your trusted list… then as soon as you visit the site with an external domain name, boom, your see the warning pop up.
Apparently, SharePoint is trying to access “Presence” information that is available in Office, and for some reason they decided to name this ActiveX “name.dll”, which really couldn’t sound more like a trojan horse. Asking for more information on the ActiveX control doesn’t help either. Most end users get immediately turned off to your website, and generally its just not a very professional way to present your portal.
Please, feel free to try it out and let me know if you experience any problems or if you have any suggestions on better ways to tackle this problem.
