Redundant Server with Redundant Lan

[Adz83]

Hi all,

Have a small issue... im trying to configure a "redundant server, on redundant Lan" system. Using Windows Server 2003

basically each server has two network cards on different subnets....

Card one Server 1 10.193.0.10 (255.255.0.0) card two Server 1 10.193.1.10 (255.255.0.0)

card one server 2 10.193.0.11 (255.255.0.0)

card two server 2 10.193.1.11 (255.255.0.0)

each card is connected a switch (one on the x.x.0.x network, the other on x.x.1.x network)

The switches also have a PLC (programmable logic controller) with 2 ethernet cards (basically two network cards) connected to them.

PLC IP address 1 10.193.0.15, connected to x.x.0.x switch

PLC IP address 2 10.193.1.15, connected to x.x.1.x switch

when i try and ping 10.193.0.15 from the server, i dont get any respone.. when i ping 10.193.1.15 i get the usual response.. When i ping 10.193.0.15 -t and uplug the x.x.1.x cabe, it starts to ping normally.... obviously one card has preference over the other.

so my question is, is there a way to configure the two network cards in the server to send/recieve traffic at the same time??
