Thanks for the guide. But i have some question regarding the ftp function of the trimble netrs. 1) I had configure the netrs to be running on a local LAN. It seem like after a few hours the ftp server on the netrs does not allow me to ftp in. But i still able to access the web interface of the netrs. 2) For the netrs i configure a static ip and with the default gateway to the router. But i not sure if my named server field should be point to the router or leave it blank. Please help me. Thanks alot..
