Tor On Private Network

[DM]

I am trying to run Tor on an internal network and I seem to be having  
a problem with the Directory Server.  The Directory Server starts up  
but I am seeing the following message in notices.log:

Sep 02 20:44:28.840 [notice] While fetching directory info, no running  
dirservers known. Will try again later. (purpose 14)

Any idea what that means?  Also, should I set the Directory Server's  
"DirServer" to point to itself or do I need to run mulitple Dir  
Servers and point them to each other?  Here's the configuration file I  
am using:
