Hello, I'm trying to use a DHCP server, under Windows Server 2003. Just for testing, I have clients using DHCP, and clients using static IP. The clients using DHCP can ping the others, and receive the answer, but they can't be found (whan any computer tries to ping this client, it receives timeout). But the client using DHCP can ping any other client wigh static IP, and receives the answer. It's too strange. All the connections are right. I'm doing the tests using the same machines, changing between static IP and DHCP, and the behavior is just like I wrote. I tried with Windows Server, and Linux, and in both cases, the behaviour is the same. Can anybody help me? Thanks,
