Odd DNS/Ping issue

[Guest]

I've got a W2K machine that can get an IP from our DHCP server just fine.
After taking an IP, DNS works fine (resolves www.yahoo.com to 66.94.234.13).
But I can't ping anything. Not the DNS server, DHCP server, internet,
intranet, etc.

Obviously then no internet, email, ICS, etc. I can release/renew just fine.
dnsflush doesn't work. Also unistalled TCP/IP, then removed Winsock from the
registry, then reinstalled TCP/IP and still nothing. I'd like to try other
things before I reinstall OS. Ideas? Thanks much!

That you can resolve to the Internet implies
that your router-firewall is working in some
way but Ping is frequently blocked on firewalls
(ICS, NAT, ISA-Proxy server) by default.

Obviously then no internet, email, ICS, etc.

No, that wasn't obvious until you said it.

I can release/renew just fine.
dnsflush doesn't work.

What do you mean "doesn't work" -- if will fail
if the "DNS Client" is stopped or you don't
have enough privilege.

So what happens when you perform

"ipconfig /flushDNS" ?

This error message:

"Could not flush the DNS Resolver Cache:
Function failed during execution."

....indicates the DNS client is not running (which
is Ok usually, and normal for a DNS server itself.)

Also unistalled TCP/IP, then removed Winsock from the
registry, then reinstalled TCP/IP and still nothing.

That is just flailing around instead of giving us
precise behavior and error messages.

I'd like to try other
things before I reinstall OS. Ideas? Thanks much!

And doing that is usually silly any so let's just
fix the problem instead....

Post your "Ipconfig /all" (Don't type it but copy and
paste the TEXT -- not a picture -- from the command
prompt OR send it to a file then paste it in.)

Tell us about you client AND router firewalls.

Tell us about your INTERNAL DNS server if any.
....and DHCP if any.

Try a "tracert 66.94.234.13" and show that output
if Ping fails.
