Multihomed 2003 server

In a network we have a terminal server. This server (Server 2003) has two
NIC's

First NIC connected to LAN (10.10.102.2), on this LAN there is a ADSL router
(10.10.102.10) to use internet and Email

Second NIC (10.10.103.2) is connected to a separate Router with an extra
ADSL line, this line is used to make connection from outside the office to
the terminal server.



I appear that the server sometimes sends info from the 10.10.102.x segment
to the 10.10.103.x segment or the other way around.



I already changed the metric setting from automatic to manual and gave both
NIC's metric value 1



What else can I do to force the server tot send to the right NIC?



Thanks.......................

You need to modify the routing table. Or post the routing table here. This case study may help,

Routing One router goes to the corporation email server and another one goes to the Internet. Symptoms: you have one router connecting to the corporation for email ...

You should only have one default gateway on your system. That means configuring it on only one NIC. The other should be left blank. Then you create static routes to control which NIC gets outbound traffic depending on destination.
