hi, I'm running Windows Server 2008 and XP pro SP2 on Virtual PC 2007 and I'm trying to set a DHCP so the XP vm's IP is set by the DHCP. I already got the IP range and subnet mask (no 100% sure if is right, I got the following range: 10.10.16.1 - 10.10.16.254 with subnet mask: 255.255.255.0). So my questions are, is there a Virtual PC setting I have to check for this? Which is the best way to configure the DHCP? and how I know that my dhcp is really working?? thankx.
