Internal Network in Virtual Server

I need to be sure of something before implementing:
I have a live network with DHCP. I have a server that has 2 NIC's in it, both on the network. On this server, Virtual Server 2005 is running for testing purposes. I have created a Virtual 2008 server and in it's settings connected it's virtual NIC to "INTERNAL NETWORK". Am I safe to install DHCP on this 2008 server and have no routing\communication to my live networkk?

No you're not. It will acknowledge packets from your network clients and attempt to give them addresses as far as I can see.

Sorry.   I don't understand your question..

You are running 2 server in a same computer, and one of them is Virtual, and you want to "ENABLE" your virtual server, just to make test???

you have to use "private network" type

IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

I can not see an option to create a 'private network'. Can someone provide simple steps for configuring a virtual network that it is completely separate from the host machines networks so I can add my test virtual server to it?
 
Thanks

I think you are talking about something else.
I want to setup a completely separate, private virtual network within virtual server 2005 that I can assign my Virtual 2008 server too (and any clients I may wish to add at a later date).

hi!
If you are talking about 2008, can you use hyper-v instead of virtual server 2005?

from_expCommented:
actually I would recommend to use hyper-v if you have windows 2008 license.

Why don't you use a diffierent IP range and domain name. That and a different mask will stop any dhcp dns problems etc.

I am using Virtual Server 2005 on a Win2003 host. I want to setup a completely separate\private network (within Virtual Server ) so I can install DHCP safely on my virtual servers without affecting my main network.
Can we stick to the question?

if you want to run a dhcp server on your virtual machine and want to make sure it doesnt interfere with the existing dhcp you have to run it in a private network.
however, if you still want network access to the virtual server, you should add another virtual NIC which is connected to the existing network.

dhcp packets on the private network will not be broadcasted to the external network unless you bridge the two

thanks noisy cricket, so how do I create a private network in virtual server 2005?

felnyCommented:
I agre with leegclystvale: just use a diferents ip range?

leegclystvaleCommented:
Your question was can you install and start DHCP in your current setup, which I answered......  NO and told you the reason why.
You have asked other questions since which people are giving their time to answer and help. My reply about a different ip range, mask, subnet and domain would allow you to do what you want to do.
Sorry but your response was rather unappreciative of the responses you have been receiving. Hope that helps

I didn't really direct this comment at you leegclystvale it was more to avoid the Hyper-V tangent the question was going towards. We posted at the same time and as it happened my post was after yours.

If you want to create a private network in Virtual Server 2005 you go the STATUS page by opening a web browser and navigating to http://<VIRTUALSERVERNAME>. From there you go under "Virutal Networks" and choose "Create". This network will be totally self contained and NOT CONNECTED to the outside world.

You can also use the VMRC+ to connect to your Virtual Server and add the network.

PeteAuthor Commented:
dfxdeimos when you choose 'create' does it not ask for type of network to be created? can you be a little more specific?
I assume my test server in question can go on this network (with a safely separated DHCP server) and any clients I wish to add to my server?

dfxdeimosCommented:
There aren't different types. The only option you have to set is "Network Adapter on Physical Computer = None (Guest Only)". That makes it so the VMs that are attached to that network can ONLY communicate with other VMs (that are attached to the network obviously).

Your assumption is correct. As long as that network is set to "None (Guest Only)" it is totally isolated from your other network.
