Instead of configuring a virtual machine as a DHCP server, you can use the virtual DHCP server for your virtual network.
To configure the virtual DHCP server:
1. Open the Virtual Server Administration Website.
2. Under Virtual Networks, select Configure and then click the virtual network.
3. In Virtual Network Properties, click DHCP server.
4. Check the Enabled checkbox, then configure the necessary DHCP server options.
5. Click OK.
