This must be done for each user's home directory ($USERHOMEDIR). You might have to be root on the fileserver itself, or a no root squash machine.

1. Delete the offending file:
   rm ~/Library/Preferences/Microsoft/Office\ Registration\ Cache\ 11
   
   
2. Make sure you're in the right place:
   cd $USERHOMEDIR/Library/Preferences
   
   
3. We're about to open up the user's ~/Library/Preferences/Microsoft folder, so
   we need to lock down the user's ~/Library/Preferences/ folder first:
   chmod 700 .
   
   
4. Give the user's ~/Library/Preferences/Microsoft folder permissions like
   /private/tmp: anyone can create a file, but only the user that created a
   file can rename or delete it:
   chmod 1777 Microsoft
   chown 0:0 Microsoft
   
   
5. Change directory to Microsoft:
   cd Microsoft
   
   
6. Create the file:
   touch "Office Registration Cache 11"
   
   
7. Make root own the file, so the user can't delete it:
   chown 0:0 "Office Registration Cache 11"
   
   
8. Make it so that the user can't read or write to it:
   chmod 0 "Office Registration Cache 11"
   
   

Now what? The user can run Excel and Word and do insert object, etc, and it
all works. The only bad thing? You have to do that stuff up there for each
user (script it), and you get a few seconds delay each startup because there
is no cache.
