Hello, I have a server that houses DNS, DHCP and AD. From this server I can ping and tracert other server and client machines. However, no machine can ping or tracert this server, be it hostname or IP. I can connect to the server via remote desktop, UNC path and to its shared drives. This has caused an issue with DHCP clients not being able to find the domain when signing in because no connection=no DHCP server thus resulting in each client to give itself the AIPIA address of 169.x.x.x. The clients and the server are on the same subnet with the only thing between them being a Ciso Catalyst swith. The server is a w2k box and the clients are 2k and XP. For a quick fix I have set each client with a static IP and everything works fine like this. I want it to work right and I want to fix the problem not just put a bandaid on it. Does anyone have any suggestions that I can try?
