Have you ever received the error message “Can not add the user because a user with that name already exists” when trying to add a user in SharePoint 2003? Well, there’s a fix. Most people overlook the SharePoint users collection because it is nested in a different web than the admin web. So, to see a list of users, visit http://ServerName/_layouts/1033/Siteusrs.aspx where the ServerName is the name of your web. For more information, visit the Microsoft KB and look up 893696.
