我已经将IIS授权了，但仍然会报这样的错误，是怎么回事呢？？

<%
                set rs = server.CreateObject("adodb.recordset")
                sql = "select contenttop,content,datenow from yhly"
                rs.open sql,conn
                if not rs.eof then            
        %>
        <div style="width:690px; height:380px; border-style:solid">
        
             <div style="width:350px; height:30px; border-style:solid; float:left">留言标题：<%= rs("contenttop") %></div>
            <div style="width:305px; height:30px; border-style:solid; float:left">留言时间:<% = rs("datenow")%></div><p></p>
            <div style="width:680px; height:150px; border-style:solid">留言内容：<p></p><%= rs("content")%></div>
        </div>
        <%
            end if
            rs.close
            conn.close
            set rs = nothing
            set conn = nothing
        %>
