How to remote 2nd server in 2nd LAN?

I have few servers on work where main server IP is 192.168.100.1 and this server provides internet access. I don’t administer this server but few others. Second server which I administer have fixed IP in same subnet 192.168.100.200 and have also fixed IP address on second NIC 192.168.200.1. This server I can access remotely. 3rd server which I want to remote have fixed IP address 192.168.200.50. I can’t ping this server from workstations because all workstations gets IP via DHCP from first (main) server and everybody logon to this server and get access to internet. Only way to access resources on 3rd server is to enter server UNC name in explorer or full UNC path to get a file from specific folder. What do I need to do to take remotely 3rd server over with fixed IP address in other subnet 192.168.200.50 without placing new NIC (all slots are full) so that this server is not exposure to attacks from internet? This server have important data and because of that reason is so in network implemented. All servers have installed Terminal Services in Remote Administration mode and works with Windows 2000 server.

First server IP = 192.168.100.1 (provide internet access via DHCP to workstations) (can access remotely but is not under my supervision)

Second server IP address of NIC 1 = 192.168.100.200 (can access remotely and is under my supervision)
Second server IP address of NIC 2 = 192.168.200.1

Third server IP NIC 1 = 192.168.200.50 (under my supervision, want to remote, but can’t ping this one from workstations because of first server)

At first when I read this, it looked like you had a routing problem - but I'm not so sure now.

Is this correct - you can browse files on it, but cannot ping it?

If thats right, it sounds like packet filtering - maybe its in a dmz or something. - what device seperates the subnets?

Sounded on first read like routing to me too, i.e. you might need a route added to the internal computers to get to subnet 192.168.200.x, i.e.

route -p add 192.168.200.0 mask 255.255.255.0 192.168.100.200

but then I was confuused by the being able to access files too.  Please clarify!

Have found a solution by implementing IP address on 2nd NIC for 2nd network. So when I log on to first server I use Remote Desktop to logon on 2nd server witch I can't ping.

Interesting.  Well you have a solution by the sound of it but you should have been able to fix it with some routing or firewall changes without needing another NIC.

Can't change anything on firewall and routing. That's another part of storyand is not under my supervision.
