Hi, I finally could added a computer to a domain and was also able to restrict my own objects to users. Ok, now actually I use the Internet connection share to other 5 PCs, I plugged the main cable connection to the "uplink" from the miniswith and all PCs have access, I also set "obtain ip addess automatically" but now that I have this server 2003 and I did specify a static IP address: 192.168.0.1 and client computer's DNS that same IP address how can I have both services Internet access and DC?

Thanks.

Your domain controller has to be able to tell your computers apart.  You will have to give each of your computers on the network a unique IP address, but put the server computers' 192.168.0.1 address as the gateway for the client computers. In each client computer, give the generic 255.255.255.0 for the DNS. This should work.



Hope that helps!

ok

i didn't understand this part:
"Your domain controller has to be able to tell your computers apart."

you have a domain controller but you use it to share out the internet, so I made the assumption that your computers are on the domain but not seperated by IP address. Please correct me if my assumption is wrong.

yes all the computers are in the domain, we use it because we can control restrictions. before using the domain controller we plugged the main connection cable to the uplink port of the miniswith and all computers attached to it got internet access automatically.

thanks :D

That makes sense. You can control internet access through the server then. How are you sharing out your internet connection. Unfortunately MS has several ways to share it out and if it's not correct, it can not mix in an AD enviornment so well. You should install the DHCP service on your server if you are sharing out your connection though it.  It can be found by going to "Configure Your Server"--->Add/Remove Programs--->Networking Services--->DHCP . If you do this, you will have to go back to your client computers and make sure that the IP address and the DNS addresses are set to "set IP address dynamically" and "set DNS address Dynamically". This should work for both Internet and your AD.

Hope that helps!

hi Kittrick, now i want to know if i can keep my connection at it is. We have the main ADSL in the uplink at the miniswitch and that gives everyone internet access. So now with this scenario if I install th e server 2003 with the DC and the AD can I have these users gain access?

With the uplink these users have gotten dinamic IPs address 200.x.x.x and I set server 2003 with 192.168.0.1

thanks :D

yes your users will gain access to both. You could keep your network "as is". Looking at your numbering scheme, it looks like maybe you are having problems because your computers are technically on different networks the way your IP addresses are set up. Can you get into the uplink and change settings?? If you can, you might want to change the settings to assign your computer the same number even though they are dynamically assigned. Many routers/firewalls will allow you to change the settings. Chances are, if your IP address is so different on the server than the rest of the network, the DNS for it is probably different too with no one else on the same subnet. That's why you won't get both Internet and server access by the clients.  You could also assign a static number on the server that is in the same range as those assigned by the miniswitch and assign the DNS the same as those clients on the network. You can find this out on the clients by going to the command prompt and typing :
        ipconfig /all

Hope This Helps!

ok, i cannot setup the uplink from the miniswitch because it's a very small one and it's cheap :D ok I'm going to first try adding a 2nd NIC to one of the workstations and assign one internet and static IP and keep the one that's provided from the ADSL and see what happens. Thanks.

You won't need to install a second NIC if you had the 2003 server DHCP...the data flow would look like this:

                                                  miniswitch
                                                        |
                                                        |
                                                 Windows 2003 server
                                                         |
               ======================================
               |                |                 |                    |           |            |
  THE COMPUTERS ON YOUR NETWORK CONNECTED BY DHCP SERVICE ON Windows 2003 SERVER


even though your actual network physically is wired like this (using the miniswitch as a hub I'm assuming):

                                                    miniswitch
                                                           |
                        ===================================
                         |        |           |                  |                   |              |
                                   ALL COMPUTERS ON YOUR NETWORK

yes my network is like the last diagram. We like that because we don't need to have one computer to be turned on to share the Internet connection. A question if we implement as your first drawing if the server 2003 is crashed or turned off the rest of the PCs will loose access to the Internet? thanks Kittrick

Yes, you will lose connection to the internet with the first diagram if the server goes down because all traffic is routed through it . If you just changed the IP number on your server to reflect the IP range of your clients it should work for both internet and AD for your clients.

Kittrick now, i know it might sound crazy but i guess it's the only thing we can do, so imagine if we just add a 2nd NIC to our workstations so we have real IP addresses from ISP and the other is for internal to connect to the server, so should this way also work? that's the only thing i'l like to know. Thanks a lot.

Your idea for a second NIC will work, but it's counterproductive because you don't have enough ports anyway for the miniport right??  I've done the two NIC config before, but it was only because we had an internal network we wanted to seal off from the rest of the company. Is it safe to say that you don't want to put your server on the network?? All of your computers are given dynamic IP addresses anyway...which means they are probably class C addresses not visible on the Internet because the DHCP server by your ISP issued them for internal use only, but can be seen by those in your company with the same IP numbering schemes. It's up to you depending on what you want to do, but unless you want to wall off your server from an outside office or something, I think it's counterproductive.
