Hi,

My exact problem is that the XP Pro client is not acquiring a new IP address from DHCP. I read somewhere that the client will try to pick up the same IP from DHCP if it can. So my question is how do I get the client to acquire a new/different address. I have already tried ipconfig /release and ipconfig /renew as well as ipconfig /flushDNS but it still does not acquire a different address. Maybe I have to set the lease duation to lets say one minute so the lease will expire before the client will acquire a new address? I am not sure. I have checked the client setting and these are pointing to the correct DNS, DHCP, etc.

Thanks,
