Unable to connect to Internet through VPC (Guest OS : windows 2003

Hi ,

I'm facing a issue while configuring Shared Networking (NAT) for my VPC.I
basically want to access the web through my virtual PC.
I am using a standalone laptop & use it to connect directly to the web
either through broadband / dial up modem.

Below are the settings on my system & steps that I have followed (as per
suggestions on the web):

1)Host OS : Windows Vista .I have no proxies configured on the Host OS. And
its a stand alone laptop.
2)ICS is enabled on the Host for the connection accessing the net.
3)Guest OS : Windows 2003 Server , DHCP enabled .
4)Microsoft VPC 6.0 with shared Networking enabled.
5) I have configured static DNS server IP to 192.168.131.254 on my Virtual
PC. When I access a web page from my VPC , I get the error "Internet Explorer
cannot open Search Page" .

I also tried the below config for the Guest OS. But to no avail.

Default Gateway :192.168.131.254
DNS IP : same as that of the Host OS ,connection.
Guest IP :192.168.131.1

It seems that the Guest OS is able to send data , but unable to receive.
Is there any settings/configuration that I have missed out ?? I'm totally
lost.. Kindly guide.

TIA,
Girija

p.s: I'm not into networking , but i'm trying my best to get this working

You should not need to configure anything manually. If you set it to
Shared Networking (NAT) the vm should get the config it needs automatically.

A server OS does not work well as a NAT or ICS host, but changing the
DNS setting (as you have done) should solve the problem. What happens if you
do an nslookup of a public address like www.microsoft.com?

You should not run ICS on the host and use Shared Networking (NAT) on the
guest. Use one or the other, not both.

Thanx Bill , I could finally get to connect to the internet through tthe VPC.
Below are some of my findings .

Connected using ,
1) Shared Networking
2) Using Loopback Adapter and ICS.

However , after enabling Shared Networking on my VPC , I still had to
manually set the IP address , Default Gateway & DNS Server information

Default Gateway : 192.168.131.254 (for win 2003 server)
DNS Server : the one assigned to the host by the ISP.
& weirdly enough it worked only when the IP Address was in the range of
(192.168.131.64 -192.168.131.190 ) (It was an accidental finding though .
I copied the values for NAT as is from the doc
(http://download.microsoft.com/downlo...whitepaper.doc)
and it worked ) .Though ,no where it has been specified that the IP has to
fall in that range .
[And for the last so many days i have been trying it with the ip
192.168.131.1 ]

However , when I set the ip to one of the values in the said range , I was
getting a warning message in the VPC "Windows System Error - A duplicate name
exists on the network" . (My host and VM have different names ) .

Though , I have got things working , those are few doubt's that are still
lingering in my head .

2) Using Loopback adapter was quite a straightforward approach .
->Installed it on the Host
-> Enabled ICS on my internet connection on the host.
-> Configured Loopback adapter on my VPC
I could connect to the web , access my VM from the host . However, it didn't
work the other way round.i.e connecting the Host from the VM inspite of
unblocking the firewall fro the VPC.

Thanx Once Again .

girija,
MLA is needed when there is no additional physical adapter in the machine
but good that u got thru

follow these steps to solve yr issue;

1. which ever adapter [lan/wireless] on host is used for net access; right
click on it from network connections and enable net sharing option.

i hope the net connection is giving u dynamic IP. also install the VPC
service on that adapter. for more info check this
http://claytonj.wordpress.com/2007/0...c-to-internet/

2. enable the default VPC adapter [intel 21..] with dynamic IP setting

3.in yr VPC window edit->settings select the host's adapter being used for
net access [lan/wireless]

4. restart yr VPC and i hope yr problem will be solved

if not then do share further details
