Connecting to ISP but can't ping

If someone's met this before then the answer's easy, otherwise...

I have a 2 node XP Pro peer-to-peer wthrough a DLink switch ith modem dial up ISP and a Laserjet 1200. No firewall. File sharing, printer sharing and ICS fine.

Everything worked fine for a while and then stopped.

I've been given some anecdotal evidence that the Laserjet's the guilty party and that I need to reinstall my NIC. Have uninstalled NIC device driver and rebooted, but no help, and can't remove the card cos it's onboard.

Am going to try to reset the IP stack and also update the Laserjet 1200 driver tomorrow, but would love to hear anybody's thoughts.

IPConfig tells me that everything's fine, even the ISP's client and server addresses, but ping just gives me an Error 65.

Am really embarassed with this one! Help please...

Unless the laserjet is trying to access the wan, it should not cause a problem.Some isp`s servers (more and more these days)will not respond to a ping anyway.
You should have a firewall for any internet connection.

Sermon over.

Does your main machine connect via the modem?

If so, ICS is a likely problem.

You say ipconfig is ok, but on which machine?

just check that the isp's DNS servers have not been reconfigured, or that you are not on a different ISP subnet .
Is everything set as dynamic ?(ip,dns,etc).
some isp's if you drop the line for a few hours,you end up with different ip, subnet mask, dns servers, etc

Everyone who referred to ZoneAlarm was right. I wasn't running it, but I had been, and it was still blocking!

Removed and reinstalled - all working fine now.

Thanks to all

Thanks. Had removed ZoneAlarm but it was still doing its worst, so I reinstalled, downgraded its security settings and it all worked.

Have now reinstated firewall security.
