Hi. We're running Server 2003 with a DHCP server. The DHCP side seems
to be working fine. We have various reserved address [all below .100]
and 20 IPs [.181 to .200] reserved for those that don't have a
reservation.

When we took a PC [Win XP SP2] off static address and tried to renew,
it could not pick up a reserved IP address [even though the right MAC
was used]. Even after removing the reservation, it couldn't pick up
one of the 20 un-reserved addresses.

It's a "flat" network with 1 segment and 1 router. Other clients are
fine.

The "repair" feature in win XP didn't help.

Ideas?
Some type of IP flushing?

Thanks

Is the DHCP service running on the client?

Check with possible firewall / anti-virus settings on the XP PCs.

Most firewalls automatically allow the DHCP to go in and out. Looked fine as
it is....
