Dual-line Dual IP is very good, netcom users to access the Netcom line, telecommunications users access to telecommunications lines.

Many people will choose to import static routing table, this approach seems perfect, in fact, a lot of problems.

1, if the telecommunications user is resolved to the IP of Netcom, the server will return to the telecommunications line according to the routing table, but the user requests is the Netcom IP, so the user can not get anything, as if you bought something from the first floor, the mall is on the second floor to you ship, and do not tell you to go to the second floor to take.

2, even if the correct resolution, but if the education network users, the server will be because the routing table does not have IP records and will not return anything.

3, IP is constantly changing, there are additional, to keep the road from the table is really too tired.

The existence of any of the above three articles, I don't think you would consider using a static routing table.

OK, here's the point:

Windows 2003 default dual network adapter configuration is problematic, often without reason, there will be a network card disconnected, frequency, time is uncertain. The reason for this is that Windows has its own "Dead Gateway Monitor" feature, and first we have to close it in the registry.

Disable dead Gateway Monitoring

Open Registry

Hkey_local_machine\system\currentcontrolset\services:\tcpip\parameters

Right, new DOWRD item: EnableDeadGWDetect, value set to 0

This value will not take effect if it is set up to reboot the server.

At this point the problem is half done, the gateway will not jump back and forth, but this time there will be a network card can not connect.

Because Windows allows only one default gateway, to resolve this issue, follow the Feather hill.

Lower right corner tray has two network card connection icon, a telecommunication, a netcom, click one, open Network card property interface

Figure Open the TCP/IP Protocol Properties page

Continue, point "advanced (V) ..." button.

Notice the contents of the red box in the above image, which is the focus.

The metric for the default gateway, set to 2

The tick of the automatic hop count is removed and filled into 10.

Another card is the same setting.

This setting is complete.
