Clients registering with RAS IP address

[Simon George]

Hi all,

I have RAS running on my DC which has an ip add of
192.168.1.200. RAS also creates a ip add. of
192.168.1.37. For some reason some of the client machines
recognise the RAS address as the official IP address and
this causes major speed issues and pressue on the server.
How can I stop these clients using this address without
turning off the RAS? Any ideas guys?

Regards,
Simon

Use the DNS console then bring up the properties of the DNS server, on the
Interfaces tab set the DNS listener IP as 192.168.1.200.
Then add this registry entry using regedt32 to stop the DC from creating the
blank A records for all IPs, then you will need to add two blank records for
192.168.1.200, one in your <dnsdomainname> zone and one in the
gc._msdcs.<dnsdomainname> subzone. (Provided this DC is a Global Catalog for
the gc record)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters

Registry value: DnsAvoidRegisterRecords
Data type: REG_MULTI_SZ

LdapIpAddress
GcIpAddress

Hi Simon,
You can't make the clients quite using the address, you have to make
the server quit registering the address.
The only way to do this is to force the server not to register ANY
addresses in this case. Then you can delete the records that you don't
want and leave the records that you want the clients to use. This article
explains the different registry settings you can use to accomplish this.
