Thinking out aloud - Dave Hunter's SharePoint Blog

With your typical intranet with MySites scenario you have two front-end web applications, one hosting your intranet and the other hosting your MySites.  These are two separate components.  MySites are a shared service, they are designed to be consumed by one or many web applications.  Out of the box they aren't linked to a web application hosting your intranet.

When a user creates a MySite they may ask you "how do I get back to the intranet?".  You can do this by setting the Portal Connection.

First take a look at my environment

1. Browse to the MySite host settings page.  In my case this is http://mysites/_layouts/settings.aspx
2. Click on the "Portal Connection" link
3. Enter the URL to the site you wish to connect to.  In my case this is http://intranet
4. Enter a descriptive name
5. Click OK.
