Network problem on Virtual PC's

Hi folks
I have set up 2 Virtual PC's: vm1 and vm2 running advanced server 2008. One
runs as domain controler. Both bult up on company PC with static ip.
my pc has ip: 172.188.3.99.
I set up 2vm's as:
vm1:
172.188.3.102
dns: 172.188.3.102
gateway: 172.188.3.102

vm2:
172.188.3.103
dns: 172.188.3.102
gateway: 172.188.3.102

now, vm1 can not ping vm2 (172.188.3.103)
vm 2 can ping and see vm1 (172.188.3.103)

One of the problem I see is after i finish network properties set up and go
back again, I see that network ip is set to some bogus address: 10.1.1.1
what i am missing here?

Do you have two NICs in the VM1? In the VM1, should not set gateway pointing
to itself.

Right.
And you don't even need a GW, unless you need internet access.
In that case, you'd specify the router as the GW.
And unless VM1 is a server running DNS, you should be pointing to your ISP
DNS servers there.
Also, make sure the Windows firewall is turned off on both machines. That
would block the ping.

Hi Robert

I have 1 NIC on host pc and 1 nic on vm1 and vm2. What should i specify for
gateway?
If i copy gateway specification from my host pc, shouldn't i register both
vm's in real domain controller?

Haliluya!

it's working now. I turned off firewall. All working. Even Internet is
working!
Unbelievable break through!
I did specify gateway from my host pc.
However, i crazy thing i see:
On vm1 when I go to tcp/ipv4 properties, i see
10.1.1.1 as ip address. Than 'advanced' shows 2 ip addresses,
and ipconfig /all shows correct address.
I feel windows interface to ip setup is not as representative as ipconfig /all

Thank you guys for your input, i really apprecuate your help.

Gateway settings have nothing to do with that. That should all work
without a default gateway at all. The gateway setting is only required to
see machines in another network (or the Internet).
