Set up as router?

[shannanl]

I have a small server that is in our Radiology department (we are a small hospital). They have several machines such as a CT, Ultrasound that use TCP/IP. These machines are on a different subnet that the rest of our LAN. I have this server with two NICS acting as a router between the two nets. Randomly this machine looses its connection to the lan. The only thing I can see is that when I run IPCONFIG the gateway is not there even though it is set in the properties along with I.P., DNS, etc. It just seems to lose this. We have installed 3 servers in the department over the last couple of months and two seem to do it. The third went two weeks with no problems. Can this problem be associated with the routing? I have changed all the cables, switches, etc. and we still have this problem. We also have 75 other workstations and about 6 servers that have no problem. None of the others are running this two NIC configuration.

Thanks,

Shannan

Why don't you just add the Radiology equipment to the regular network and forget using the routing features of Windows?

I have a similar setup for a stubbed test environment. This is how it looks:

Prod--------RRAS-------Test/Switch
Two Nics:
Prod 1 (interface to the production network
IP - 192.168.254.10
SM - 255.255.255.0
GW- 192.168.254.1 (gateway/Interface on production router)

Test 1 (Interface to the test network)
IP - 10.0.0.1
SM - 255.255.0.0
GW - No Gateway

Routing Table for Default Route is:
Destination - Network mask - Gateway
0.0.0.0 0.0.0.0 192.168.254.1

Make sure you do not have two entries in the routing table of the Default Route, this can cause issues. If you do have two default routes; remove the Default Gateway, in TCP/IP, for the interface facing the radiology network.

Of course there could be other issue:
Are you using and IP scheme that is already used on the network?
How is the routing table being created? Static? Dynamic using RIP or OSPF?

I agree with FloDiggs, if you can use your network equp (Cisco) to creat a new subnet and route traffic. But that information is not provided so we can't assume the equpment exists.
