Você pode tentar o Configurador de redes PE :
PE Network Configurator or PENetCfg is a stand-alone utility that allows you to start and configure networking in Microsoft WinPE and BartPE.
With PENetCfg you can do the following:
- Enable and start networking support if it's not started yet.
- List all Ethernet adapters on the running machine and set TCP/IP properties (IP Addresses, Default Gateways, DNS Servers, WINS Servers
- any number of them) and switch between using static and dynamic (DHCP) TCP/IP settings at any time.
- Select Link Speed/Duplex Mode of a broad range of Ethernet adapters.
- Add any Domain, workgroup, or Server to browse its resources and map and disconnect network drives.
- Change computer name and join workgroup.
- Release and renew the IP address of any Ethernet adapter.
- Change the MAC address of any Ethernet adapter on the fly.
- Use network profiles to automate configuring network settings. For more information about using the network profiles, see the included readme.txt in the downloaded package.
O nome do computador pode ser predefinido no arquivo PNETCFG.INI
em [NetID]
.
Por exemplo:
[NetID]
ComputerName=the-name
Workgroup=workgroup
Eu nunca usei este aplicativo e não posso garantir que ele ainda funcione com as versões mais recentes do Windows.
