why can't I ping the other computers?

What IP numbers do the computers have when you type ipconfig /all at a DOS prompt? Did you try running ipconfig /renew_all at the DOS prompt?

First of all what are you using for an isp? If you are using DHCP,then your IP address should change,(being assigned from your ISP).
Get rid of NETBEUI, it overrides TCP/IP.
Can you ping yourself?
After disableing NETBEUI, try pinging the othercomputers by computer name instead of address.
Good Luck!

First of all, I would uninstall all the other protocols, both IPX/SPX and NETBEUI are broadcast protocols and create unnessarary traffic. The reason why you can share files and printers is because of the other protocols and not via TCP/IP. Are you trying to ping the other computers via the computername or via the ip address of the computer. If you are using the computer name you will have to register the computer onto the other computers via the lmhost file, that is if you are not using a wins,dhcp or a dns server. Well for sharing to work you have got your workgroup/domain configured correctly. It could be that your switch is blocking your TCP/IP traffic. If it is a managed switch install an IP address onto it and check what its settingsare. Good Luck.

Are you using firewall software? You're probably able to share files and folders using netbeui. Go to the properties of the nic cards and see what protocol(s) they are bound to. If ot selected check tcp/ip.

First of all don't know your OS, MS internet connection sharing the host will be set to 192.168.0.1 by default so this should be your host address. set to that reboot and try to ping your self at 192.168.0.1 if that works but still can't ping otherip addresses try and manually set media type on adapter properties start at 10 half and work up. Also update AV and run a scan there are viruses that attack the wsock files in system folder and disrupt TCP/IP functions. Your file sharing and printers are probably using either IPX or Netbeui to talk. Remember to set the default gateway for all PC's to the host for internet sharing. IF your running XP make sure the MS firewall is disabled on your interface for testing and reconfigure once TCP is working.

Dump everything but tcp/ip.
Buy a SMC7004ABR Barricade Broadband
router.
This thing is a 4 port 10/100 SWITCH, a DHCP
Server/Client, Print Server, firewall, and has a
rs232 port for a dial up modem.

In other words you hook your modem up to
this port and it shares the internet connection
to all of your computers.

Once you go to dsl or cable it has a
broadband input as well.

Good Luck Lee

The only other thing I can think of trying is going into the properties for your NIC and changing media type from auto to whatever your hub supports IE 100 /half duplex and give that a try. Also I've found that Intel NIC's have a setting called adaptive technology and this has caused some issues.

Check all IP settings are in same range and that none are duplicated.

If you're using ICS then set all PCs to obtain IP automatically.

Uninstall NIC and all protocols and re-install with only TCP/IP. (Having other protocols present will only complicate fault finding)

Are u using different NIC cards?
If ye, set the sever to hardware negotiotan and the other pc's to there 10baseT or 100BaseT
lock them, and try again

This is the answer that solved the problem.There was a vxd file left in from ZoneAlarm which was preventing the connections to ping.This file is "vsdata95.vxd" The file was removed in DOS before booting.Then there was the message that the file was missing,I continued to boot and removed the reg key using the "find" in regedit.Actually I am using a great reg editor called "VilmaRegestryEditor" it is freeware,I suggest that anyone that does work with the registry try this program.The problems that I had are gone and I am able to share my dial-up connection now.Thanks for everyones help and I hope this info will help the next suckker that uses ZoneAlarm.Personally I prefer BlackIce.
