Home network and DNS problems

[Guest]

Archived from groups: microsoft.public.win2000.dns (More info?)

Hello,
I have a small home/office network. The server and domain controller is
win2k sp4+isa2000+exchange2000.
I had many errors in system log with regards to to dns, netlogin etc...

By reading this newsgroup, I managed to correct them all.
Both the ADSL PCI modem and the network adaopter "Register this connection's
addresses in dns" are checked.

The problem today is even though no error is shown in the log files, I have
intermittent problem of network connection loss and delay that can take 3 to
30 minutes. During this time, I lose the server, and other programs like ISA
Client will lose connection with the ISA server; Outlook will not be able to
contact the Exchange server and no Internet will be available.
After this time, things will be back to normal and no error will show up in
the log files on the server nor on the client side.

Here is a Netdiag output which shows some errors that I don't know where to
look for correction.

Thanks for you help

I can see why you didn't see it because your original subject:
Cannot find a primary authoritative DNS server

was also someone else's subject and it fell under that thread. Happens
sometimes. You can look back for that thread with the other person's name it
for it. For your convenience I reposted below Kevin's response and my
response below that.

Here is your biggest problem, you cannot use any external DNS in TCP
properties on any interface, you must use only the local DNS address on
all interfaces. Configure this interface with IP of the internal interface
for DNS.

You can configure these DNS addresses as a Forwarder for your local DNS
server as per this KB article:
300202 - HOW TO: Configure DNS for Internet Access in Windows 2000
http://support.microsoft.com/?id=300202&FR=1

825036 - Best practices for DNS client settings in Windows 2000 Server and
in Windows Server 2003
http://support.microsoft.com/default.aspx?scid=kb;en-us;825036

Another problem is this DC is multi-homed, multi-homing a DC requires
additional configuration to prevent the public interface addresses from
being registered in DNS. This creates a problem for file sharing and the
SYSVOL DFS share and can cause userenv 1000 events to be logged.

Please follow these steps.
1. In the DNS management console, on the properties of the DNS server,
interfaces tab, set DNS to only listen on the private IP you want in DNS for
the server.

2. Add this registry entry with regedt32 to stop the (same as parent folder)
records.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters

Registry value: DnsAvoidRegisterRecords
Data type: REG_MULTI_SZ

LdapIpAddress

(If the DC is also a Global Catalog see note below)

3. Create a new host in DNS, leave the name field blank, give it the IP of
the internal interface. Win2k barks at you saying (same as parent folder) is
not a valid host name, click OK to create the record anyway.

4. Right click on Network places, choose properties, in the Advanced menu
select Advanced settings. Make sure the internal interface is at the top of
the connections pane and File sharing is enabled on the internal interface.


Note-

If the DC is also a Global Catalog use this registry entry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters

Registry value: DnsAvoidRegisterRecords
Data type: REG_MULTI_SZ

LdapIpAddress
GcIpAddress

And in addition to the (same as parent folder) record in the domain zone for
the domain name, expand _msdcs, open gc create new host with name field
blank and give it the IP of the internal interface. This resolves as
gc._msdcs.forestroot.

Hi Mich,

Whenever it comes down to a multihomed DNS/DC, especially with the PPPoE
software (WinPoet), we see this alot in here and in the AD groups. Kevin's
suggestions are right on the mark, that is if you want to go thru all of
that, which even with folks like Kevin, William, and the others that post
and help out here and as long as we've been in the business, we would rather
not change our default system settings, but have done so for many a client.
Usually the easiest way to circumvent all of this is to purchase a USD
$39.00 Linksys DSL/Cable router (there's a rebate going on for them) that
will securely connect your network to the Internet. Then you can connect the
LAN side to the ISA box without the PPPoE software that is required for
ADSL, which is overhead and causes issues.

If you can, ideally, ISA should be installed on a member server or
standalone, depending on what mode its in. Part of the issue is the fact its
a multihomed DNS/AD machine, which causes issues with AD and DNS, as you're
experiencing. If you can get another machine for this function, (depending
on the number of users, a decent desktop will do the trick) unless of course
this is SBS, (which you can't separate ISA and other features), that would
improve performance, especially withoput the PPPoE software.

Unless of coures, you can follow Kevin's suggestions, which is what we
normally suggest for this sort of scenario.
