Two networking cards

Hi there,

Here is an interesting question. We have two servers, each of them has two
networking cards, all of them connect Internet directly (two subnets,
155.57.19.xxx and 155.57.44.xxx), but only cards on 155.57.19.xxx sets up a
gateway, 155.57.19.254. My question is both cards on one of servers work
very well, computers on both subnets 155.57.19.xxx and 155.57.44.xxx can
access both cards, but one card on the other server works not well,
computers on 155.57.44.xxx can access 155.57.44.72, computers on
155.57.19.xxx can access 155.57.19.237, but computers on 155.57.19.xxx
cannot access 155.57.44.72.

Configuration of working one as
Windows 2003 Enterprise Version SP1
An Intel dual port networking card

Configuration of non-working one as
Windows 2003 Standard Version SP1
One Intel(R) PRO/1000 XT Network Connection and one Intel(R) PRO/100 S
Server Adapter

I don't know why one of them doesn't work. Is it networking configuration
problem, Windows 2k3 version problem or networking card problem? In fact, I
cannot figure out both two networking card connecting with Internet.

Please see the attached route tables, the top one is from working server,
the bottom one is from non-working server.

Thanks.

Ray
