In chris <

below
Normally we recommend not to multihome a DC due to various problems
associated with such. Is this also a DNS server? Makes it a bit more
intriguing. What I could recommend to alleviate this, assuming that one of
the NICs is to the outside world, possibly offering NAT or just as a router.
This is under the assumption that the two NICs are NOT teamed.
1. Outside NIC:
Disable NetBIOS
Disable MS Client Service
Disable F&P Services
2. In DNS (if DNS is on it)
Interface tab of properties, only listen to internal IP
The above should take care of the NetBIOS issues with not registering on the
network. You can also view its registration by using nbtstat -n.
Now if this DC is also a DNS server, more to come...
3. Now this part is to ensure the outside NIC's IP does not register itself
or it will create some issues with the LdapIpAddress, which normall creates
a record under the zone that looks like this below, but what happens is it
creates two of them, and we don't want that to occur:
(same as parent ) A 192.168.5.200 (or whatever the IP is)
Also, it creates an extra GC address, called the GcIpAddress. We just
want the internal NIC to register.
So in the registry, we'll need to kill these two things. To do that...
Add the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlog
on\Parameters
Registry value: DnsAvoidRegisterRecords
Data type: REG_MULTI_SZ
Value: LdapIpAddress
Value: GcIpAddress
4. Then manually create the (same as parent) record with using the internal
IP.
5. Manually create the GC record under the _msdcs._gc zone.
So you can see its really recommended to multihome a non- DNS member server
rather than a DC and especially a DC/DNS server. I know SBS you don't have
much choice, but it's administrative overhead to take care of it.
