Hi, I have been trying to test PXE boot Window PE using the Linux server, faking a MS RiS by following the guide written by Gianluigi Tiesi (Linux-RIS). I started by using the above to do a remote install of w2k3sp1, which worked very well afterdhcpd/atftpd/smb were set properly. Then, I went further to test the same logic for WinPE (opk2005). The client (WinPE) booted ok, and I could ping from the client side to the server, but I could not ping from ther server to the pe machine. There was no firewall enabled. I put ethereal on the server to check the outgoing icmp packets, there was no echo from the other side. However, the smb traffic between the server and the client was ok. I tried to put ethereal on the pe too, but it failed to detect and network interfaces. Initially, my testing settup contains only the server(pxe) and the testing client, but I tired to add another machine, which was able to ping the server and the server was able to ping it to, but neither of them was able to ping the pe machine, and at the same time, the pe machine can still ping both of them. I wonder what I have missed here, will appreciated any comments, and thanks in advance.
