I have a Dlink Ethernet router connecter to Windows 2003 server. All computers could see each other and access the internet. I have to put an external computer in a shop across the road and have purchased a Sitecom wireless router and wireless pci card to connect. All set up and internet connects fine. I cannot however access the server or even join the domain. Keep getting a message that the domain is not found. I can connect to the PC's including the server using the ip address but conversely none of the other computers can now see the wireless networked pc.
