Development site Up navigate takes me to production site.

Hello,

I am having an issue with a new production build, I will call it, Production B. On Production B we restored from our current production, Production A. Things work fine pretty much when navigating. Here is the issue. In Production B if I use the SharePoint 2010 'navigate up' folder icon, to go back to our company home page, it takes us to Production A.

So on Production B, my path is \\companyhome\teamsites\Advertising\ProjectA.

If I use the 'Navigate up' and click on either teamsites or Advertising, I stay within Production B. If I click on 'companyhome' it takes me to Production A.

We had an issue similar to this for some sites using Absolute URLs over relative URLs. I was able to go into the sites navigation settings to change this.

However, I don't see how to change the setting in the 'navigate up'.

Any ideas?

Thanks
