I only said to shut down the clients that have the conflict. The reason is
by shutting down, they send a release.
You have 5000 clients and multiple DHCP servers, that paints a different
picture. That is why it is important to explain the network so we know how
to answer.
So, these clients are RRAS clients obtaining an IP from your servers as part
of the connection. You need to state that.
Deleting all of the leases on all the DHCP servers was a bad move because
now you have thousands of clients with IP addresses that the DHCP server
thinks it has available to supply.

Hello
Thank you for your reply
We have 5000 clients and they are privet people, we provide Internet for
them we can't ask them to shutdown the computers and start one after other
So you see the problem, and also for ip detection it was before in 3 but
doesn't help
What I'm doing now when I see the bad address, I make exclusion for this
address after I delete the offer for the client with bad address to force
him to ask another ip address, and also I deleted all the address lease on
all scopes in all dhcp servers.
I'm nearly sure that the problem with the entries in dhcp server do you know
how I can edit this entries, but its possible that I' am wrong also
Thank you again
hanan

Your post is a little hard to read but from what I understand, this is what
you need to do:
1. On the client computer that received the bad address, completely shut
down the computer.
2. On the client computer that had the IP address first, completely shut
down the computer.
3. On the DHCP server, in the DHCP MMC, under Address Leases, delete the
lease for both computers.
4. On the DHCP server, in the DHCP MMC, right click on the server and
select Reconcile All Scopes.
5. On the DHCP server, in the DHCP MMC, right click on the server and
select Properties. On the Advanced tab, in the Conflict Detection Attempts
box, chose 3.
6. On the DHCP server, in the DHCP MMC, right click on the server and
select All Tasks, then select restart.
7. Then restart each of the client computers one at a time, ensuring that
each one has been completely started before starting the next.

Hello tom
My problem is not on isa server but with dhcp server
I have bad-address this ip is already in use in dhcp server; I tried several
methods to resolve the problem but no way
I have ip detection enabled for 1 time
What I think that the dhcp server when detect duplicate ip address it mark
it as bad-address in its entries the problem is the dhcp don't remove these
bad-address from the ip address and when offer it to the client it offer it
with the link bad-address, if I' am right I want to know how I can remove or
change those bad-address from the dhcp entries
The dhcp server is a window 2000 and my clients are windows 98 connect to AP
via wireless
Any help it will be appreciate it
Best regards
hanan
