Thanx for your repaly..
Basically i don't need iframe scrollbar. i have one default.aspx page in that page top pane (Image) , contentpane , bottom pane (copy right etc).
Now in content pane my iframe is loaded that is diffrent source (http://localhost/DotNetNuke/Default.aspx")
My both source is configured in same domin or machine.
Please see this url for more idea.. http://wb.ibsgi.com/

As per your security suggestion How i set low security settings ?
