Currently, I have two other (non-DC) servers running with no issues on the domain. NAT works as it should, and internet access is just fine. The CentOS box on the same network will not receive an IP address (only through static configuration, the non-DC 2003 boxes have no problem receiving an IP and DNS settings with auto settings) or get online. Even when defining a static IP on the CentOS box, there is no Internet access, unlike to the other clients. My question is, what could be restricting the DHCP and DNS information to the CentOS host, and why can't I access the internet/NAT forward a web server?
To summarize, I have four machines involved, all located on the same network:
- Machine 1 - Windows Server 2003 Enterprise - Domain Controller, DHCP server, DNS server, NAT server.
- Machine 2 - Windows Server 2003 Enterprise - Domain member, Exchange server.
- Receives DHCP and DNS information with automatic network settings.
- Has internet access through NAT.
- NAT forwards ports to this host.
- Machine 3 - Windows Server 2003 Enterprise - Domain member, Sharepoint Server.
- Receives DHCP and DNS information with automatic network settings.
- Has internet access through NAT.
- NAT forwards ports to this host.
- Machine 4 - CentOS 5.4 - On same network as other clients, hosts web server.
- Does NOT receive DHCP address or DNS information.
- Has no internet access
- NAT does NOT forward correctly.
Any assistance on this problem would be greatly appreciated.
