Windows Server 2008, member server networking issue / gateway connection issue
I have a network with two windows 2008 servers
My gateway server Netserver has mutiple network cards , the public one connecting to our router ( 210.73.149.238 )
Public
IP 210.73.149.233, subnet 255.255.255.0, gateway 210.73.149.238
Private
IP 192.168.1.1, subnet 255.255.255.0, gateway 192.168.1.1
Netserver is the AD / DNS Server / DC and all client pc's can access the internet when they use 192.168.1.1 as the gateway
--------------------------
My exchange mail server is a member server and is located on IP 192.168.1.2
It has a private card
IP 192.168.1.2,subnet: 255.255.255.0,gateway 192.168.1.1
It CAN send emails out and does so fine, however the machine its self has no internet through IE7 and no client pc's can connect to it in this state.
Network shows a diagram with no internet access
Why is this relativly simple network not working ? I have tried lots of different settings now but still no luck. Is there a set procedure when changing network card settings to ensure they are correctly adopted ? At the moment, I change the settings , then disable and reenable the card and the settings kick in.

Try deleting the gateway for your private IP on Netserver. You should only have one default gateway.
Looking at what you wrote, Netserver is acting as a router for your Exchange Server. Do you have 'Routing and Remote Access' enabled and properly configure on Netserver? You may want to look at this:

Above suggestion is one of it. Check the following instruction from MS on how to set up the network property for ISA on SBS:

Raehrlich is on the money with his post.
I have another question though, is this SBS or just straight server 2008? Also, have you considered putting in a firewall/router combo to handle this instead of putting it all on your PDC/AD server?

Its straight windows 2008 server, the router is acting as the firewall also , its BT Business Hub
What I REALLY wanted was both machines live, with exchange sending through its own public IP because it has a second card I could use, however when this scenario is configured the clients cannot reach exchange. You may ask why I want this , the answer being that the IP for this (live) mailserver has been authticated for mail delivery to AOL , HOTMAIL etc as is complete with reverse PTR record from BT
But I reasoned that I cannot have the gatway set to this live IP as the mail would be delivred to the gateway and not to the exchange server
Im sure I am not explaining this well at all, is there a live chat facility on here I can use ?
How can I ensure the settings are correctly applied when changing them on the card ? Microsoft networking gives me lots of different views of the network which dont seem consistent with my setup

Ok good, so I will remove that as suggested. Will that resolve the connectivity issue with the mail server ? 192.168.1.2 ?
ASKER
WIth that corrected are the mailserver settings of
IP 192.168.1.2,subnet: 255.255.255.0,gateway 192.168.1.1
correct ? or can I have the gateway blank but add 192.168.1.1 as the DNS and then connect my public IP network card as suggested above ?

Server Hardware
Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
