Just took over admin on a Windows 2000 SBS and am seeing some odd DNS symptoms
First, the forwarding function on the DNS setup is grayed out. Can't seem to find the settings to bring it back into functionality
Second, and I believe related. Windows 2000 clients, but especially Windows XP clients are taking forever to log into the system
Any suggestions on documentation to diagnose the setup of DNS?
 
First, the forwarding function on the DNS setup is grayed out.


You have to delete the dot "." forward lookup zone that is created by
default. This will allow you to configure forwarders.

Sounds like they are pointed to the wrong DNS server probably your ISP's DNS
server which is wrong.
AD MUST have a DNS server for AD. Point the AD DNS server to itself for DNS,
point all AD clients to the AD DNS server ONLY. Set up forwarders on your AD
DNS Server and list your ISP's DNS servers as the forwarder.

Thanks Danny, they both worked!

Hello All,

Just some general guidelines for a basic AD/DNS setup.



Active Directory with DNS on the same server.

TCP/IP settings

1.)Right click "My network places" and select properties.
2.)For the LAN connection right click and select properties.
3.)On the properties page double click TCP/IP
4.)At the bottom of the protocols page select Preferred DNS Server option
and enter the IP address for the server itself.
5.)Click the advanced button. In the advanced setting make sure the
"Register this connection's address in DNS" selection is checked at the
bottom of the display.

DNS settings

1.)Open up the DNS console.
2.)Once opened, right click on the server in the right hand pane and select
properties.
3.)Once the properties page is up, select the "Forwarders" tab.
4.)Check the "Enable forwarders" selection at the top.
5.)Add the IP address of the DNS in which to forward requests. If this is
the only DNS , add the IP address for the ISP's DNS. (note- In the TCP/IP
settings, we selected the choice for DNS to point to itself. If name
resolution cannot be resolved then a request is made to the forwarders. If
resolution cannot be made via the internal DNS and there are no forwarders
listed, then resolution will be made via the root hints.)
6.)Click OK.
7.)Expand the "Forward Lookup Zones"
8.)If there is a folder with a dot "." listed then delete it. (note- This
indicates to the server that it is the root server, which means do not go
beyond this server for name resolution.)
9.)Right click the domain folder and select properties. Make sure that
"Allow dynamic updates is selected."

Close out the DNS console.

Open up a command prompt and type the following:

1.)At the prompt type ipconfig /flushdns and wait for the services to
flush.
2.)ipconfig /registerdns wait for the services to regiser.
3.)net stop netlogon
4.)net start netlogon

If you receive an error during this process go to control panel, admin.
tools, services. Make sure the DHCP client service is started, even if
they are not using DHCP they still need the service started. Once all of
this is done. Open the DNS console again. Expand the forward lookup zones,
then expand the domain folder. You should see the underscore folders below:

_msdcs
_sites
_tcp
_udp

You would have to delete the dot forward lookup zone before you would be
able to configure forwarders.
