problem in connecting two virtual machines for local network only

HI,
I have Win xp professional sp3 as my host OS, have one lan card with static
IP from ISP

I have created two virtual machines in Microsoft VPC 2007.

First virtual machine runs Win xp sp2 with only one network adapter 'local
only' (in virtual machine networking settings) and have IP 192.168.1.21
Second virtual machine runs Windows Server 2003 with only one network
adapter 'local only' (in virtual machine networking settings) and have IP
192.168.1.20

Now the problem is while running both virtual machines simultaneously I can
ping from my XP machine to Server machine and also able to take a remote
connection. But when I try to ping from Server machine to XP machine I get
error request time out and also can not connect using remote desktop.

Re: problem in connecting two virtual machines for local network only

That sounds like a firewall problem. If you can ping one way, your
network setup is correct. The ping request can travel from one machine to
the other and the pin reply can travel from the target machine back to the
original requesting machine.

The firewall on the XP machine is blocking ping responses. This is the
default behaviour from SP2 onwards. You need to change the setting for
the firewall to allow ping (and also the other protocols you want to
use between the two machines).
In fact, since both are on local only it seems like there is no need
for a firewall at all, there is no outside connection to worry about.
So you can disable the firewall altogether on the XP machine.
