Client OK but can't ping

I'm trying to use Remote Desktop Connection to connect to a client (from the
internet, not internal). If I use the client's IP address I succeed, but if
I use the client's computer name I fail. Upon further investigation, if I
remote into my server first (Windows Server 2000), then try to ping the
client, it fails whether I use IP address or computer name. If I look in the
forwarding zone of DNS on the server, the record correctly maps
192.168.1.212 to RWWS1, which is the client I'm trying to reach. Where
should I look for the root cause of my problem (not being able to RDC to the
client with the computer name). The client functions perfectly on the
network by the way, this is just a RDC problem. TIA.
 
Hi Dan,

You arent trying to RDP with the client's internal ip are you? :-)
Do you have an externally registered domain name for this company? If
yes..check that whoever hosts the external DNS mapping has it correctly set
to the external ip with the registered domain name, if that is it has ever
worked via ext dns. You basically need a record set which points the
external ip to the registered domain name of your clients server which runs
the RDC. There are many companies who host dns and domain registration, a
google search will find some. Alternatively you could host the ext dns via
the clients server but that wold mean opening up more ports and additional
configuration, and you would still need a registered domain name.
This is a great site for DNS tools to help you troubleshoot.

I see that my post is a little confusing. When I encounter my problem, I
already have a secure connection to my network via a Sonicwall SSL-VPN. My
problem is with this specific client- I can easily RDC to any other of the
clients on the network using their computer name. Since I can access the
client using the IP address, it would appear to be a DNS problem, but why
can't I ping either the IP address or the computer name from my server, and
again, the forward zone correctly maps the IP to name?

Hi Dan,

Ahh ok thank you for the additional info. :-)
Since the issue symptoms are only in connecting with this client, I would
start troubleshooting there. Have someone, sitting at the pc, confirm that
it is configured set to dhcp with no static entries(assuming that that is
how it is supposed to be). Have them do an ipconfig /flushdns as well as an
ipconfig /release, and then you manually delete the dns record for their pc
off the server. Also flush the DNS cache of the DNS server. Have them reboot
and then confirm they picked up an ip, also check that there is a new dns
entry on the server for them, if not then they should do an ipconfig /renew
and a ipconfig /registerdns.

Lets start with that and see what happens.

Another question.. do you happen to use vlan in this network?
Also try doing a pathping to this pc and we can see where it fails.

Also you could try changing the switch port the pc is on.

hi,
when you ping -a IP it's show the name of computer, on ping by name it shows
the IP or is a error? check the status of dns, the registration of the
computer and run a clear cache on DNS servers.

also check on the server and on that client the "route print" to see what
routing table do you have and may be that IP is routed elsewhere.

Thanks I'll give these a try.
