Guest dan Posted August 26, 2007 Posted August 26, 2007 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.
