I am having a problem where Ubuntu is not communicating with my windows 2003 DNS server. I set up debug logging in the DNS server and got nothing from my IP when trying to ping the address of the PC. In VMware I can ping the address and it is logged and works. I have tried the address of the new DNS server as a primary and secondary DNS server in Ubuntu, but I think the settings are being sent by DHCP (which works in windows as I said before). I don't know if it is a security issue in Ubuntu or 2K3 so I don't know where to start.
