What is a multihomed DC?



Is a Domain controller with more than one Nic (Network Interface Card) card



What do I need to change on my server to mave this work?



Well you said that now you have everything working except Internet, and you
also said that you don't have Proxy or any other thing that
prevents/restricts users to access to the internet, so you must have a DNS
resolution problem.



- Do you have Forwarding enabled in the Dns server? If no go to the Dns
console -> right click Dns server choose properties -> select forwarders
tab -> Select All other Domains -> got to the Selected domain's forwarder
Ipaddress list and place the ISP Dns server address -> click add -> restart
Dns service.



Test the resolution on the DC - Go to command prompt and type ping
www.microsoft.com - check if returns the Ipaddress of the site, then go to
the clients and check if the ping command returns the Ipaddress of the site.



Are you saying I shouldn't have WINS and DNS on the same computer?



No. What I said was in a Multihomed DC you could have problems with Wins and
Dns.


FYI I uninstalled WINS and see the same problem, do I need to remove some
records somewhere?



You'll only need WINS if you're using any APP in your network that needs
NetBIOS resolution or if you have the need to browse over different subnets
using for example Network Places.



As for configuring the DNS as you said I already had the interfaces set to
only use the local Nic.



- Great


As for setting the binding order the internal Nic was at the top of the
list. How do I check to see if file sharing is only on that NIC?



- Right click on it and choose properties then you should have the "File and
Print Sharing for Microsoft Networks Selected"; however you should
disable/deselect this on the Public Interface (Security purposes).


I had lowered the windows firewall but there was a Norton Firewall that
was
preventing Laptop 2 from Filesharing. That now works. So both the
desktop
and Laptop 2 have the same issues. They get an IP, can perform
Fielsharing
but can't connect to the internet.



Check also if is preventing Internet access or any other access to server or
Dns, etc. Best practices here are for test DISABLE the Norton Firewall and
test, in this way you can immediately check if this as relation with your
current problems.

check:

Also, make sure the internal adapter is at the top of the binding order
and
that File Sharing is only bound on the internal adapter.

- If the machines are running SP2 you need to open the FW to File share
access.
- Configure the Dns server to listen only on internal adpter (Open Dns
server mmc console -> Right click on Dns server -> choose properties ->
goto
interfaces tab -> choose only the following IP Addresses, and make sure
that
you only have the internal interface there)

Hi

- What O.S are you using for each Machine?
- Are you using some proxy device that denies internet access to some
users?
- Can you post here the results for ipconfig /all for each machine?

FYI: this is a double post because I want' sure which forum is was
the
correct place to post this question. I have also posted on the
technet
windows server general newsgroup but I think this is a better forum.

I have a 2003 Server Running as DHCP and DNS, I have 3 cleint
computers.
After adding each computer to the network I see 3 different result
on
each
computer. I am using a 2 NIC setup and I have a switch after the
server. I
plan on using wireless but I see the same result with everything
hard
wired
so lets stick with that. I have a 4 port switch that hard wires each
computer.

Laptop 1 - Works as expected, 1) gets IP address 2) can see the
other
computers on the network thorugh Windows Explorer and perform
fileshare
fine
3) Connects to the internet correctly.

Desktop 1 - Doens't work 1) gets IP Address 2) can see the other
computers
on the network thorugh Windows Explorer and fileshare fine 3) NO
INTERNET
CONNECTION?

Laptop 2 - Doesn't work 1) Gets IP Address 2) CAN'T SEE OTHER
COMPUTERS
OR
FILESHARE, BUT I CAN PING THEM? 3) NO INTERNET CONNECTION

I have tried many things. I can unplug the cable from laptop 1 and
place
into either desktop 1 or laptop 2 and s/ same results. I can uplug
cable
from Either of the non working computers and they both work in
Laptop
1.
So
that makes me think this has nothing to do with the hardware.

I'm not sure what else to tell you about, I can see Laptop 2 from
the 3
Computers but can't actually open it up, but it does show up on the
list
of
for the Domain in win explorer.

As for the TCP/IP settings everything is exactly the same on each
client
computer.

In the Computers area of Active Directory everything is the same for
all
three computers.

Just to try it out I set up reserved leases for each NIC they work
fine,
each computer signs on and gets the resevered IP Address.

I have no idea where to go from here, please help.

Thanks in advance,
