Cannot ping client, even on LAN

I'm going to repost this issue since the my information in the other post
was getting confusing. I have one client on a small LAN that I cannot use
Remote Desktop Connection to access, even fromt the LAN, although I can
access all other clients with no problem. Upon investigation I find I cannot
ping the client from my server (Windows Server 2000) with either IP address
or computer name. If I run pathping, I see the computer name is resolved to
the IP address so DNS is working. Pathping reports 100% loss of packets on
the first hop- failure. I can ping the other way, from client to server,
just fine. I've checked the firewall setting and it appears to unblock TCP
port 3389 as it should. What am I missing? thanks.
 
Re: Cannot ping client, even on LAN

Hello,

can you make a telnet IPADDRESS 3389 ?
after issuing a ping, do arp -a
do you see the mac address about this ip ?

Check properties in the computer tab of workstation that you can connect
through RDP

Mathieu, thanks for the quick reply! No, the telnet fails to connect.
What is the exact command for using arp? thanks.

Thanks I'll check that when I get on site to look at the client. The arp -a
does not show the client's IP or MAC address.
 
Re: Cannot ping client, even on LAN

if just after a ping, you can't get the arp (or 00-00-00-00...) then it's
not alive, at least on this ip

RE: Cannot ping client, even on LAN

hi,
what subnet mask do you have set on client and on server? Do you have set
any TCP filtering on client? what firewall do you use on client machine -
some firewalls have the abbillity to mark some IP addresses as "no access".

Dragos, it's the standard /24 subnet mask, and the Firewall is XP SP2
version. I'm going to check the firewall settings again (maybe even turn the
firewall off temporarily while I try to figure this out, but I've got to be
on site obviously, since I can't remote in....
