Re: DHCP-DNS

Thank you for your reply.
So this way the dhcp will manage all the dns registration and deletion.
Although there is a lease time, the clients will be able to release the dhcp
lease with the "002 Release DHCPlease on shutdown". Am I correct ?

I have a test lab of Windows 2K3 R2 dc, windows 2K server (dhcp client) and
Windows XP Pro (dhcp client). I did all you said and the dhcp registered the
records on the dns for both clients. The lease time was 5 min. for test.
When I shut down Windows 2K server, it did not release the dhcp lease. I
thought it should do so according to dhcp server options. Then after 5 min,
the leased ip was with an "i" on the the computer and still the dns had that
ip registered. I read somewhere that dhcp keeps that ip up to 4 hours. Is it
correct? Does this mean if I had a 3rd. machine the lease would be different
ip ?

The user account that you mentioned in DHCP, Advanced tab in Credentials,
does it have to be powerful user (special group) or a regular user ?

Thanks,

Haim

Ok. How can I configure only the DHCP server register the ip's on dns
and not the machines to register themselves except servers which have
static ip's ?

Clear the check boxes "register this connection's addresses in DNS" on all
clients.
In the DHCP server properties *** (DNS tab) check these boxes:
"Enable DNS updates..."
"Always dynamically update..."
"Discard A and PTR records..."
"Dynamically update... .DHCP clients that do not request update..."

Select the Advanced tab, click the Credentials button, enter the username
and password of a dedicated user account with a non-expiring password.

Manually delete all PTR records in the zone. (So the DHCP server can take
ownership)

Select server options, Advanced tab, select Microsoft options from the
drop
down list, place a check by 002 Release DHCP lease on shutdown.(0x1)

You will still have some records left by clients that are not gracefully
shutdown and laptops that are disconnected without releasing the lease,
but
when the lease expires, DHCP will remove the registration since it now
owns
the record.
