I'll start off with what works (:-)):
I have a 3 computer network (workgroup), each computer connected to a HUB all using Windows XP PRO. One of the computers has an internet connection and shares it.
(IPs are 18.104.22.168 up to 0.3) with the gateway set to 192.168.0.1.
Each computer can access all the shares on the others with no problem (no need for username/password, nothing).
Up to here everything is fine.
I got a new Laptop (also XP PRO), but I don't have a port where I wanted it. So I stuck in another NIC in 192.168.0.1 (my "main" computer), connected it with a crossed cable to the laptop (192.168.0.6 and also on the same workgroup).
All the computers can "Access" the shared folders of the laptop.
The laptop can PING all the others. But
Now the problem:
If on the laptop I enter a computer name, for example "\\main\" it doesn't find the computer. But if I enter the IP "\\192.168.0.1\" it finds the computer but asks me for a local username/password. If I enter that, I get access to the shared folder.
And - although in the "Network settings" it "sees" the shared internet connection - it doesn't find any internet site.
Anyone have any ideas?
