john <johnbah...@xxxxxxxxxxx> requesting assistance, typed the following:

I am running win2k3 with 2 NICs. I have a Comcast modem connected to
the internet. My problem is that the connection to the LAN cannot get
any private addressing. It is just frozen on Acquiring Network
Address. I have unistalled and the installed DHCP, put a new NIC, new
switch, new cable, but LAN just cannot get any addresses. Any ideas?
Thanks.

Hello John,

You've already heard some of the issues and nuances about DHCP and
multihomed servers from Phillip and KJ.

What I am curious about is your network's configuration. Can you respond to
the following questions? This will help to better understand what you have
running and where the issue may lie.

1. An unedited "ipconfig /all" from the server
2. In Network and Connections, Advanced Menu, click on the Advanced
selection in the menu. Let us know which NIC is at the top of the list.
3. Does this server host DNS?
4. Is this server a domain controller?
5. Can you provide the DHCP scope (IP range you configured DHCP to give
out), along with the subnet mask, and any Scope Options you've configured
(such as Option 003 for the router address, Option 006 for the DNS servers
list, and any other options you may have configured).
6. Curious, why are there two NICs in the server? Is the "outside" NIC
connected to the Comcast modem, and the inside to the internal LAN?

Would you say your network looks something like the pic in the following
link?http://www.fekay.com/supportblogs/BasicNetworkWithWindowsNATserver.jpg

You've also stated something is up with the DHCP Client service. Just an
FYI, despite its name, the DHCP Client service is actually the DNS
registration and resolver caching service. If this is disabled, a machine
cannot register into DNS, nor will it cache recent DNS lookups.

Are there any services that may have been disabled, more than likely due to
security concerns? (Post the result of a "net start" output, please).

Thank you,

1.Sorry don't know how to get that but the NICs are 75.148.199.41 and
75.148.199.42 with the subnet mask of 255.255.255.252 and 10.1.10.175
with no gateway. With this addressing clients and the server have no
problem communicating with each other. Its just that the clients can't
get on the internet.

2. I clicked on the Network Connections, but the only thing on the
Advanced Menu was two enabled NICs which were the Server and LAN 3. I
have another one which is onboard , but iut stopped working and I
disabled that.

3.& 4Yes this server hosts DNS and I am hosting my website and it is a
DC.

5. The scope is 10.1.10.10-10.1.10.199 whic is entered it myself,
since DHCP got stuck on Acquiring Network Address forever.
6. That is correct. It is how its set up. The LAN gets private
addresses listed in the scope and WAN has the address of 75.148.199.42
(gateway).

On Net Start I don't know how to send the output.

Also , DHCP client service had started but I mistakenly changed the
Log On account and tahts when it could not start again.

Thank you for your time in looking at this.
