Can't ping external IP address

I'm running Virtual Server 2005 on a Server 2008 host machine. In Virtual Server, I have two servers, one is a domain controller, and the other is a server that is not part of the domain. Both are running Server 2008. The DC works well with the host OS in that it has internet access and DNS seems to work fine. But on the second server, I can't access the Internet or ping any external IP addresses.

The first server, DCServer, has two (virtual) network adapters configured as follows:

#1: Connection-Ext (this is a Microsoft Loopback Adapter, to provide access to my LAN, which is on the 192.168.1.0 network):
IP: 192.168.0.10
Netmask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS: ::1 and 127.0.0.1

#2: Connection-Int(this is the internal adapter for my virtual network, on 192.168.100.0):
IP: 192.168.100.10
Netmask: 255.255.255.0
Default Gateway: (blank; actually, it's some IPv6 address listed; I think this is automatically handled by the loopback adapter andits installed Virtual Network Machine Services)
DNS: ::1 and 127.0.0.1

The second server, ServerTwo, has one virtual NIC:
IP: 192.168.100.110
Netmask: 255.255.255.0
Default Gateway: 192.168.100.10  <-- This is the IP address of the first server. I'm guessing this is the problem, but I don't know what address I should use here to provide internet access for this machine. If I try to set NIC #1 on the other server to use ICS, it wants to change the IP address to 192.168.0.1, which I can't do. Is there some other way I should configure the first server to allow Internet access (and pings) to go through it?
DNS: ::1 and 127.0.0.1 (DNS seems to be working fine as the ping command can resolve hostnames to IP addresses)

Thanks in advance for any help.

I thought you had to be in the same subnet as the 'host' server for this to work (or use NAT).

The normal mode would be bridged so your restricted to whatever sub netting you have available for you normal network.

Even the two server on the same virtual server but I dont think you able to use IP address of server 1 as a default gateway for the second server.  Is it the routing is done on the router not on the DC?

just my 2 cents

My other question.  
Is the 'host' Server (the physical one, the one has your 2 new servers on) able to access and 192.168.100.0 subnet?  And is this subnet able to access Internet.  If all the answer is yes, you may try to give the default gateway of the second server as 192.168.100.1

You can't set the default gateway of second server as 192.168.0.1 because your server IP and subnetmask doesn't support in that default gateway.

Make it clear.
255.255.255.0 is a /24
If you use that Subnet Mask, then only 192.168.0.2-192.168.0.254 are the available IP to be used.  192.168.0.1 will be default gateway for those IP addresses and 192.168.0.255 will be the broadcast IP.
The samething will go for 100 subnet.  All you need to do is replace 0 with 100.
IP available for use: 192.168.100.2-254
Subnet Mask:  255.255.255.0
Default gateway: 192.168.100.1

If you want your current setting to be working.  Your "host" server has to be able to access to 2 subnets (subnet 0 and subnet 100).  Then on your second server, set default gateway to 192.168.100.1.  And on the router, you have to make sure that subnet able to access the internet (routing stuff) then your second server should be worked.

Hopefully I'm not creating more confuse for you.
