Simple "Internal Networking" not working

Post by pgonzaleznetwork »

Hi,

I´ve seen many post about this but I havent found an answer. Im a networking student and Im trying to use VB to do some testing.
I have to guest machines, one running Windows 7 and the other one Windows Server 2008. I have enabled a second network adapter for each
and set it up to "internal network" and they both have the same name. Then I went to Win 7 and assigned 192.168.5.3 to the second network adapter
and then I went to Win 2008 and assigned 192.168.5.4 to the second network adapter.

The problem is they cant see each other, when I ping them,it says "session time out". Right now the first network adapter (the one configured with NAT) is turned
off on both guests, but I dont think this should be a problem. This seems to be a pretty basic configuration and I have read the manual.

Any ideas?

Thanks in advance

note: this is my first time here so any help would be greatly appreciated.

It would help if you posted the output if ipconfig /all from both guests.

Hi,

So, as you can see they are in the same network, and they adapters are set up to "internal network" and they share the same name. I can get them to ping properly. Thanks in advance

Can I assume that you really meant that they can not ping each other as stated in the original post?
If so make sure that you have enabled ICMP (ping) since by default the Windows 7 does not allow this.
