I have a home network with a linksys switch, linksys router and cable modem. 3 computers running win2k. All computers can ping through the switch, router and cable modem to the internet. All computers are able to get DHCP info/config from the router. However, I cannot ping from any one computer to the other??? I thought the switch was supposed to "route" traffic between the computers when the addresses are local. DHCP is assigning 192.168.100.10X addresses. Submask is 255.255.255.0 Router has a 192.168.100.1 address on the LAN side. Thoughts? Network looks like this: Comp1 -> Comp2 -> Switch -> Router -> Cable Modem Comp3 -> Thanks, Lorin

Do they all have the same workgroup name? Do they have unique computer names? Are they set to "Use DHCP Server for WINS resolution"?

Yes. Yes. Don't know. I'll check. I didn't think Win2k had an option like that for WINS.. Just a WINS server entry.

Okay. Win2k doesn't have that option but I think 95/98 did. Here are the 2k options for WINS: Wins addresses in order of use: {add} {edit} {remove} Enable LMHOSTS lookup Enable Netbios over TCP/IP Disable Netbios over TCP/IP Use Netbios setting from the DHCP server. What is WINS? Thanks, Lorin

WINS is used to convert NetBIOS names (the computer names) to IP Addresses. Select TCP/IP and click Properties. Click the Advanced button Select the WINS tab Click Enable NetBIOS over TCP/IP If that doesn't work, try editing the LMHOSTS.SAM file, and make sure you enable the LMHOSTS lookup feature (on WINS tab) Add a line at the end of the LMHOSTS.SAM such as: 192.168.1.2 mycomputer

Okay. I'll give this all a try but I still don't quite get how that will fix ping. I see how that might keep network neighborhood or DNS or netbios lookup of the name from converting to an IP addr. BUT, my ping doesn't work even if I use the HARD IP addr without any lookup.??? Would your solution still hold true? It seems like a have a very basic TCP/IP problem although it doesn't make sense that all the computers can get to the router okay, but not each other via a ping. Thanks, Lorin

Ie.. If all the computers on configured on the same subnet, same mask, connected to an 8-port switch: How is possible for them to not ping each other. Does ping or TCP/IP screen who it will respond to? Is the switch not routing the packets correctly?
