DFS Site shows as "No site association" after OS upgrade

Hi,

I upgraded one of my DFS servers from W08SP2 to W08R2SP1.  Now the server shows the correct Site in the DFS Management GUI, but via dfsutil the Site information shows as "No site association" for each of the 4 dfsroots it holds. 

I tried removing the server from one of the dfsroots and then added it back, but that doesn't change the site status.

Any suggestions?

Thanks!
