Hello everyone:

Currently there are no records for the network printers in the DNS. What is
the best way to update our DNS with all the printer names?

Hi genghiz,

Are you using DCHP server?

If you are using DHCP and active directory integrated DNS server.

First reserver the one IP address in DCHP server for that printer.

Restart the printer.

I hope that the information above helps you.
Have a Nice day.

It will automatically gets the IP address from DCHP and DHCP will update the
records to DNS.

Hi Rajesh,

Actually that would depend on the printer if supports dynamic updates. In
order to make sure all printers update, whether they support this feature or
not, it is recommended that DHCP be configured to update all records,
whether the host can update or not. This setting also includes the ability
to update reverse zone records.

What is also recommended is to allow DHCP to own the record. Not that it
would effect a printer record, but this setting affects all records. So in
order for say a client that gets a different IP and to alleviate duplicate
records in DNS, DHCP would need to own the record in order to update it with
the new IP. In order to do this, add the DHCP server account to the
DnsUpdateProxy group in AD. Then in DHCP server properties, last tab, you
would provide credentials of an account that DHCP would use for this purpose
other than the admin account.

Here is more info on it. I hope it helps. This can also be found at

DHCP on DNS, Scavenging and the DnsProxyUpdate Group:

The entity that registers it owns the record. The nice thing about DHCP
owning the record is it will update it if DHCP gives the machine a new IP.
Otherwise you'll see multiples of the same in DNS whether scavenging is
enabled or not. I would force DHCP to own the record as well as enable
scavenging to keep it clean. To force DHCP to own the record, you will need
to do the following:

1. Add the DHCP server to the DnsUpdateProxy Group.
2. Force DHCP to register all records, Forward and PTR, (whether a client
machine can do it or not) in the Option 081 tab (DHCP properties, DNS tab).
3. Set Option 015 to the AD domain name (such as example.com).
4. Set Option 006 to only the internal DNS servers.
5. If the zone is set for Secure Updates Only, then DHCP cannot update
non-Microsoft clients and Microsoft clients that are not joined to the
domain. In this case, you will need to create and configure a user account
for use as credentials for DHCP to register such clients.
If your DHCP servers are Windows 2003 or WIndows 2008, Configure a
dedicated the user account you created as credentials in DHCP by going into
DHCP COnsole, DHCP server properties, and on the Advanced tab of the DHCP
Properties sheet click the Credentials button, and provide this account
The user account does not need any elevated rights, a normal user account
is fine, however I recommend using a Strong non-expiring password on the

Once you implement scavenging, you will need to wait at least a week for it
take effect. You can quicken it up by manually deleting the incorrect
records to
get started.

But more importantly, if DHCP is on a DC, it will not overwrite the
original host record for a machine getting a new lease with an IP
formerly belonging to another. To overcome this, add the DHCP server
(the DC) to the DnsProxyUpdate group. This will force DHCP to own
all records it will create moving forward and will update an IP with
a new name in DNS.

If you set this, but when a record shows up in the DHCP Lease list with a
(which means that a write is pending), it m ay mean it is trying to register
into a zone that does not exist on the DNS servers. This happens in cases
the client machine is not joined to the domain and has a missing or
suffix than the zone in DNS. It can only register into a zone that exists on
DNS and that zone updates have been configured to allow updates.
If this is the case, go into the client machine's IP properties, and
on the DNS tab in TCP/IP properties, clear the "Register this connection's
addresses in DNS" as well as the "Use this connection's DNS suffix in DNS
check boxes, the DHCP Server will fill these in for you and register using
the domain name in Option 015.
