Hello Everyone,
I try to connect three computers into a network with using 4 ports switch, CAT5 cabing and internal NIC. Those computers using Windows 2000 pro. And I assign the IP address and subnet mask to them and change the workgroup name. Finally I can see those computers with each other and sharing the resources. But the main problem is,I can't ping those computers, the message said " request time out" The main purpose I set up in a network is playing online game... and I try to unistall the TCP/IP and Install it again, but it still doesn't work, can you guys give me some suggestion for me? Thanks a lot

what ips and subnets did you assign.

my computer is so fast, it completes an endless loop in less than 4 seconds!

I choose a Class B address
150.50.16.10~150.50.16.12 &
Subnet mask is 255.255.240.0

can each machine ping itself?

that makes no sense.

If you can't ping yourself, and you're using XP, then open a dos prompt and type "netsh int ip reset resetlog.txt". That'll reset tcp/ip.

If you continue to be unable to ping yourself, try a 192.168.0.~ IP, and then your subnet will set to 255.255.255.0 (I believe), which might work better.

Do you have ZoneAlarm or BlackIce or some similar software firewall running? If so, turn it off and see if that makes a difference.

are you pinging by IP or by machine name?
