Exchange 5.5 Public Folders

We restored our Exchange server from backup after having removed the server from the site. Initially, we kept our Public Folders structure and data. After less than a day, our Public Folders were shown as residing on our Bridgehead server (2nd server in site). The folder structure remained, but no data. We went into Exchange Administrator and changed the "Home Server" Properties for our site from the Bridgehead Server back to our Primary Server. Still no data for Public Folders, although the Pub.edb file shows 122mb on our Primary Server. How can we cause our Public Folders to read the data from the Pub.edb file on our Primary Server?
