I'll insert more details in the next 5 hours but this is the issue I'm facing:
I have 2 LAN NIC :
one of them, pre-existing & connected all these while are working
fine & its gateway is the default gateway for this server.
I just connected another cable (from another LAN) which was tested
working on my laptop to LAN 2 : by connecting/disconnecting & observing
status of LAN 2's network "Status" from Windows 2003, I'm positive this
port is LAN 2 which shows as "Connected" now (after I did "Repair" on
LAN 2, then it got activated). I've assigned an IP addr & mask to LAN 2
but without gateway set on this NIC port
However, when I tried to add a persistent static route (the exact persistent
route command which I previously (errr about 2 weeks ago) was able to add
successfully on my laptop, it rejected with an error that the gateway was
unreachable or not on the same subnet. The command was "route add
192.168.128.0 Mask 255.255.252.0 192.168.200.1 -p"
I'll attach the exact screen shot & commands in a few hours' time
