Hello, I've the following network configuration : - Netgear ADSL modem, router, firewall and 100MB switch on this switch are connected my 100 MB computers and a - Netgear 100/1000 switch on this switch are connected my two 1GB computers : desktop and laptop Every thing works fine with XP for file and printer sharing, but when my desktop runs with Linux and a samba server, file sharing works but I'm unable to print from windows boxes to the printers shared by my desktop, even from Windows running with VMware in my desktop !! I tried a lot of things and found that if I force my desktop NIC to run at 100MB everything is OK, but I loose the capabilities of my 1GB subnetwork. Any suggestion to solve this issue will be welcome. Thanks in advance. Michel.
