Change link URL for logo in header on a SharePoint 2010 site?

In SharePoint 2007 I can go to site settings -> Look and Feel -> Top Link Bar to set the url for the image link on all sites/subsites to point to the site collection site.

 

In SharePoint 2010, Site Settings -> Look and Feel -> Title, description, and icon

That should control the top icon in a team site. What site template are you using?

try accessing the page directly _layouts/topnav.aspx

or

Go and edit your master page(in sharepoint designer or if it is place on your vs) which you can find sharepoinnt icon tag like this and change the LogoImageUrl to you Url.

 

<SharePoint:SiteLogoImageid="onetidHeadbnnr0"
 LogoImageUrl="/_layouts/images/titlegraphic.gif"runat="server"/>
