Adding a computer to my network with a pre-set IP address

[liberybell]

I am sorry if this is not in the right forum.
I am trying to add a computer for a training session at our company to our domain. For whatever reason this computer must maintain its current IP address (no created by our DHCP) So I need to be able to add this computer to our domain with the IP that it currently has. Is this possible?

If the IP address falls within the LAN's address space, then yes. What is OS of the pc and of the LAN's domain controller?

 

[liberybell]

No sure of the OS, I just know that they told me that for this training session they must keep the current IP address.Otherwise they will have to rework the entire setup for this B2B workshop.
Our LAN's domain controler is Windows 2003 SP1.
Sorry about my lack of knowledge on this. I am just trying to help our new Network Administrator to do this on a network that he is not really familiar with.
Is there any way I can run the DHCP command:
add reservedip with the corresponding IP and MAC numbers?

 

[stfaprc]

There is not enough information to go on.
Does this pc need to join the Domain/LAN or just be able to access the LAN and the internet ?

 

[liberybell]

Just to have access to the LAN and the internet.

Is DHCP handed out by the Windows 2003 Server?If it is, you can set up a reservation that the MAC address of the PC always gets a specific IP Address.

It sounds like the pc does not need to join the domain. Is the address space of the LAN non-routable?
If so, I suggest just adding a second IP address to the pc that falls within the LAN address space. So if LAN address space was 192.168.111.1-.224, set up a second IP address of 192.168.111.99 (making sure that .99 not already used)

Try giving it a static IP address, and then create an exclusion in the server so that the ip address won't be given out.

You can use this procedure to create an exclusion range for an existing DHCP scope.

Membership in DHCP Administrators, or equivalent, is the minimum required to perform this procedure.

To create an exclusion range in DHCP

1. Click Start, click Administrative Tools, and then click DHCP. The DHCP Microsoft Management Console (MMC) opens.

2. In DHCP, double-click the server name. For example, if the DHCP server name is DHCP-01.example.com, double-click DHCP-01.example.com.

3. Double-click IPv4, and then, for the scope for which you want to create an exclusion range, double-click Scope.

4. Click Address Pool. Right-click Address Pool, and then click New Exclusion Range. The Add Exclusion dialog box opens.

5. In Add Exclusion, in Start IP Address, type the IP address that is the first IP address in the exclusion range.

6. In Add Exclusion, in End IP Address, type the IP address that is the last IP address in the exclusion range, and then click Add.

7. Click Close.

Never mind we decided to set that server on its own separate network with its own hub.
Thanks to everybody for your help.

My concerns on this would have been how would it contact any of the other machines if you couldn't change the IP address on the training machine and it was on a different network address range of your corporate network. Whilst the data would be travelling on the same physical network cable the two networks wouldn't be able to communicate because of lack of gateways.

Glad you decided to move it onto a seperate lan environment.
