We are running 8.8 and use the software deployment portal for users to install additional software that they may request. However I have found that if you deploy Office 2010 partway through the install the portal stops refreshing and displays a message as below.
Cannot find Server
Page cannot be displayed
The install completes successfully however it is not ideal having the portal "break". My guess is that Office 2010 is updating a component that portal relies on.
