hi,
How do I delete the cache of the ip address of a PC ??? (In case the dhcp is
not working good, so I do a release and renew of the address and I still get
the old ip address. This address is taked from the cache of the ip address
that was in this pc , which is NOT good for my check of the dhcp server ).
If the DHCP were "not working" good you would NOT
get back (the same) IP address -- you would either get
the updated versions if the scope on the DHCP server
had been altered or you would get back an address from
a different DHCP server (presumably a different address
since you would not have your two servers distributing
the same addresses) OR
....you would get no address after the release and failed
renew.
If you wish to change the addresses then this must be done
from the DHCP server.
By default (as you likely know), the client is asking for
the same address as it used previously which causes no
problem since the DHCP server will ONLY agree to renew
or assign this address IF it believes it valid and suitable.
It is perfectly allowable for the DHCP server to return an
offer of a new/different address to the client.
If you really must "delete the client's knowledge of the old
address" (there is little reason) then you can probably do
that in the registry by finding the DHCP (client) service and
deleting the entry there (be careful.)
