Our DHCP server is set to lease ip addresses for 30 days in the 172.16.x.x range. But our Windows XP machines will assign their own ip addresses (192.x.x.x) when it can't connect to the DHCP server even when it has a current lease for 172.16.x.x. Our other workstations (win95&98) will continue to use the leased ip addresses. Is there a setting I can change on the XP machines to use the leased ip address even if DHCP server is unavailable?

try giving one of the XP systems a static IP address, let it breathe for a day or so then change to DHCP via the release renew method.

I'm not sure if this will help, but try disabling Automatic Private IP Addresing (APIPA). Q244268 has the information for 2000, but I can't find an article on how to disable this in XP. Should be the same for the most part.

Automatic Private IP Addressing (APIPA)is working properly but it is causing you problems.

Try setting a default gateway address
(see MS Knowledgebase article 220874, ...computer checks for the DHCP server and if none are found, an attempt is made to contact the default gateway. If the default gateway replies, then the...computer retains the previously-leased IP address. However, if the computer does not receive a response from the default gateway or if none are assigned, then it uses APIPAto assign itself an IP address)

Or disable APIPA
