I have searched and searched the web for answers on how to setup DNN 6 for a web farm.  I have discovered several documents and have read through them.  Some documents are for older versions of DNN and do not apply to DNN 6 and the DNN 6 document only applied to DNN 6 PE.  We are running DNN 6 CE.  We have 2 web servers each with local storage holding the DNN instance.  We have Windows DFS replication setup between the to storage locations.  We have been in development for a few months now and have had no problems with the site.  We have recently went live and are now seeing what appears to be cache problems. 

I understand that CE only has a file based cache and thats fine for us.  What we are experiencing is changes being made on one server do not appear on the other server.  DFS replication is working perfect and if I go into the other server and clear the cache then all the changes appear. 

I have a feeling that DNN might do something special like launch a file watcher if it senses it is in in a web farm environment.  My question is how do I make DNN know its in one?  If I go to the host settings, the 'Is Web Farm' check box is not marked.  I cannot figure out how to make it checked.   

Any help is greatly appreciated!
