I just got off the phone with microsoft.  5 minutes and $245 later, I was 

told to unload the Arcserve Backup agent for open files.  I did that and 

it worked, no more 80070020 message.  Some twisted relationship between CA 

and microsoft prevents an external KB article from being posted.  So I 

thought I would share to save others some $$$$.
