Hello,

we have windows server 2003 computers connected to 2 disjoint networks via
2 network interfaces.
Does anybody know a way to force TCP reply on the same interface that
incoming traffic ?

It has to do with how TCP/IP works (not Windows). It will always reply on
the interface according to the system's Routing Table. If the destination
has a specified and "known" route in the Routing Table it will reply via the
corresponding interface, but if the route to the destination is unspecified
or "unknown" (such as the Internet) and therefore does not have a line in
the Routing Table, then it will always reply via the interface associated
with the Default Gateway no matter which nic it came inbound on.
