Network Path was not found!

[prabhash]

Hi All,


I have installed a windows 2000 Advanced Server (SP4).
Promoted to be a Domain controller.
This server has 5 clients connected to it. All the clients have win Xp
(sp2).
I successfully joined each client to the network.
But after doing the join, I started configuring NAT for sharing
internet connection to all the pcs.
After a lot of googling i came to know how to configure NAT along with
active directory.
Now my problem is after configuring NAT, any of my clients can't access
the domin while logging in. It says "domain not found ..."
My network places on the server shows up nothing.
Interesting thing is when the clients login to there is pcs through
local (this computer) accounts then they can access internet easily.
But when i try to join them to the domain i constently get the message.
Could not join to domain "ourdomain.local"
"network path was not found"
My server has 2 lan cards installed.
I am pasting my "IPConfig /all" results here

Thanks in advance

Active Directory does not work well with NAT. NAT likes to use its own
DHCP-style allocator and act as a DNS proxy. If you use AD, do not let NAT
do either of these things. Do not set it to be a DNS proxy and do not give
it a pool of addresses to allocate to clients.

Remove the public DNS server IP addresses from the public NIC of the
server.

Configure your local DNS to forward to the DNS service(s) you want to
use. (If forwarding is not available, check that there is not a . at the
root of your DNS tree. If there is you will need to remove it. This makes it
a root server which will not forward to anywhere).

Set the client machines to use only the local server (192.168.0.1) for
DNS.

Hi Bill,

First of all thanks for your reply.

You said AD does not work well with NAT.
Then how do i share internet connection with Active Directory?

about my problem ... i am sorry to say it is still not solved.
1. I have removed public dns server IP addresses from the publi NIC.
2. I have already configured Local DNS to forword public DNS ips. I
have removed "." root from the local dns.
3. I don't use NAT's DHCP or DNS.
4. I don't have DHCP or wins installed on my windows 2000 advanced
server.
5. After doing all this still when i try to join to domain i get error
"network path was not found"
6. on my client pcs i have following TCP/IP configuration
IP : 192.168.0.7
subnet : 255.255.255.0
gateway : 1192.168.0.1
Prefered DNS server : 192.168.0.1

7. all of my clients can ping to server and to each other.
8. BUT my server can't ping to any of the clients.

When i use NSLookup from client it shows my my server name.
On the server NSLookup returns localhost.

Please help me.

The recommended way is to have the DC and DNS server running on a
different server from the RRAS server. A multihomed DC/DNS server can cause
problems because the server name is associated with two IP addresses. Check
that your DNS server only listens on the internal NIC. Also ensure that
Netbios over TCP/IP is disabled on the public NIC. NAT should work OK with
AD as long as you take the steps outlined.

The fact that your server cannot ping a client by name or IP is odd,
but isn't the cause of your other problems. Perhaps it is a firewall problem
