    Anybody else had any problems?

    If I install VPC 2004 I lose my DHCP IP address. Reboot didnt bring it
    back. IPConfig cant get it back. Had to do a system restore back to before
    the install. Running XP SP1 with a Broadcom Net Xtreme NIC (6.34 drivers).
    Got the NIC set up so that its a member of 3 VLANS.

    I wasnt surpised that it broke my network connectivity, but would be
    interested to hear if anybody is using these both OK....

    This sounds like you are directly connected to an ISP that (only) provides
    you with a single IP address. Workarounds are getting a hardware "DSL
    Router"/Firewall box, using "shared networking/NAT instead of (virtual
    switch), or using "loopback adapter"+"Internet Connection Sharing".

    Typical troublemakers in VPC networking are:
    - Optimizations that some network adapters has ("Network Offload")
    - Some wireless adapters
    - VPN clients (those that require *real* low level access to the NIC and/or
    wants exclusive access)
    - Some firewall software

    The normal setting for VPC is to set the network adapter in "promiscouous
    mode". In some environemts or with some adapter this doesn't work.

    VPC 2007 breaks dhcp

    I experienced the exact same issue when I installed VPC 2007 on windows xp with a Broadcom NetXtreme 57xx gigabit controller. I don't have any restore points so if somebody knows why this happens and possible solutions it would be greatly appreciated if you shared them.

    When I try ipconfig /renew I get a timeout message saying it timed out trying to connect to the DHCP server. Is there perhaps some way to directly reconfigure the connection to the the DHCP server?

    Please help me. I need to figure this out
