Hi all! I've just replaced the 3com 10mb on my work box with a realtek 8139 100mb. The card is working, I can ping other machines on the network, telnet in to linuxbox from my windows machine, use my samba share, BUT the linux box is no longer appearing in the windows network neighbourhood, and the inranet site served up from linuxbox won't display over the network (it will display using lynx on itself). Is there a file in debian where I can check the settings for a card, eg check it is configured to use TCP/IP (I think ping is UDP)? Thanks, Jenny.
