Change DA 9.0 Export Folder Default Path

We have DA 9.0 running on a Server 2008 64 bit server with the client's running on Win XP SP3.  On the client I have changed the default path for the export folder to a shared folder via the full UNC under configuration>settings>export production.  However even after restarting the client when I go to export the default path is still listed as C:\.  It is in use at the moment so I cannot recycle the services which is my next thought but I wondered if there is something else that I might be missing?  I'm doubtful that restarting the services will do anything as this is a configuration on the client and not on the server.
