Client fails to pick up DHCP address

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

Try ipconfig /flushdns, but if Repair in XP isn't working (it does that,
amongst other things) then it sounds like you've got larger issues on the
workstation. Try posting in microsoft.public.windowsxp.general for more
specific help with that....and include your event log errors. You could also
try uninstalling & reinstalling the NIC.

The fact that it accepts a static address that worked fine [Internet access,
access shares on the network, etc.] tells me that it's not a NIC issue.

I'll post the message in the XP group. Thanks
