I have just been asked to add 2 network printers and a PC to an existing network. I have completed all the cabling and the tests are ok. Problem – I am using Windows Server 2003 standard edition, I can’t see the the three new machines. The network kit comprise of a SonicWall TZ70 – Firewall, Nortel Baystack 420-24T Switch and a A BT ADSL Router. The original set up had 12 nodes all working ok. The firewall is between the router and the server. I can’t see any firewall software on the server for configurations. How do I gain access to the additional 3 ports on the switch?
