Cannot add namespace server 2008 R2

I am trying to add a 2008 R2 DC as an additional DFS namespace server and it fails during the commit stage.  The share gets created, but it is not listed as a namespace server.  There are currently 24 2003 DFS/DCs and 1 2008 R2 DFS/DC.  Also, when it fails, the error pasted below shows up.

If anybody has any ideas, it would be very helpful.  I worked with support for 2 1/2 hours yesterday and made no progress.

Thanks,

Steve
