    I have Server 2003 running on VPC 2004 and am only doing local networking for testing purposes. Both Client VPCs that are running on my box get the exact same IP Address from Server 2003. All 3 are running on my box and DHCP server only shows one lease for the first VPC that receives it.. Any Clues?

    I'm not coming up with an obvious answer after doing a google search and going over microsoft's site. The closest I came to your issue is outlined in the two links below:

    http://support.microsoft.com/?kbid=152273

    http://support.microsoft.com/kb/q303743/

    I also tried http://support.microsoft.com and searched for Virtual PC. I came up with a series of troubleshooting issues but none of them had to do with dhcp. I did see that SP1 for Virtual PC has been issued so it is possibly an issue where your software needs to be updated. It also may be an issue with your virtual server itself and not the Virtual PC software.

    I use VMware and don't know enough about Virtual PC to really give out more than guesses. I assume that your virtual netwokr is isolated from your actual real-world LAN/WAN (not bridged) so you aren't getting conflicting IP assignments from both a virtual and real dhcp server.

    Just shooting from the hip. Hopefully, someone else will drop by soon with some other ideas. You could also contact MS support and see if they have any idea. Good luck and let us know what happens next.

    BTW, since this is your first post, I'd encourage you to pop up to the new members introduction forum and tell us a bit about yourself and how you found CF. Thanks.

    I'm a little confunsed. How many computers do you actually have? If you only have one nic you should only have one IP.

    The reason I'm asking is because it seems server 2003 has "Duplicate address detection" However, you have not mention anything about error messages.
    This is what I found.
