You only need 2 LAN cards in one computer the one connected directly to the Internet Device which should be a router.

With the proper security applications installed on this machine you can then put a switch of the other LAN Port and connect the remaining computers to that. As this sounds like a simple Peer to Peer Workgroup you will most likely have to run the Network Setup Wizard again but start with the one connected to the Internet device and then work around to the rest of the machines using the this computer connects through my LAN option.

Sharing a Internet Connection and LAN this way is a waste of both hardware and time in attempting to setup as to the Network it looks as if there are 8 devices connected instead of 4 and you have to install security software on all the computers.

Wow, been seeing a lot of people using double NICs in their systems (well... "seeing" it here on techrepublic). I agree with both previous replies. Get rid of the ONE of the NICs for each machine, get a router/switch and set up the network properly.

netbios must be working but not dns, that is what it sounds like to me.
i would do ipconfig /all on each system and compare. maybe the gateway?

maybe we are getting fooled by a red herring. this a workgroup, yes? and you have confirmed a usr account exists on the pc's you get the access denied error with the same exact name and password as logged in as on the ics box?
i have rule of thumb: first take the error messages at face value (look for horses not zebras)
maybe its just a firewall issue
i would go the the support.microsoft.com mskb and search 'access denied' and try all the obvious stuff
you must have dial up or isdn to be using ics instead of just putting the router on the 'external' lan, yes?

make sure your on the same subnet and iprange

get rid of dual network cards its a bad solution, join them all up to a switch/router and share the internet through there
