broadband connection do not work in windows server 2003

February 4, 2013 at 12:16:55
Specs: Windows 7

i availed a fibre optic broadband connection from my isp and i test it in my windows 7 laptop and it works fine.

but when i connect the modem to my windows 2003 server, i cannot connect. i've 2 NIC in the server, one for LAN and other for WAN.

if i am not mistaken, i think the WAN NIC should get an IP from isp to connect. but in my case the wan nic do not get any ip. i've removed all server role from the server thinking that it might be causing the problem but to no avail. please guide me why the problem?

Is this a modem router or just a modem?

If just a modem you may need to alter the mac address on the server nic to match your windows 7 nic. This would be due to the ISP registering your windows 7 mac.

You should be using a router with the modem. Not using one puts you at risk of port trojans and hackers.

i think its just a modem. and for your info mac address has nothing to do here cos isp is not using mac address. i can connect the modem to any other systems and use. i am sure there is something in windows server 2003 that is prohibiting the assigning of ip by isp. firewal,l i am not sure but i can say i've not enabled windows firewall for the WAN nic.

previously also i had broadband connection from another isp who had assigned me static ip and it was working. the diff between before and now is the modem. before i had no modem unlike now. but ofcourse they had a canopy which is a modem or not i dont know.

"i can connect the modem to any other systems and use"

You certainly didn't state that in your first post. Only that your win7 box can but server can't.

All the signs of a mac address filter.

Firewalls usually don't block dhcp traffic without really special configuration. Getting a ip address is not a security issue.

Lets see a ipconfig /all from the server for review

i too have started believing that its a mac address issue as you suggested because the connection works only in my system. i tried in other computers in my network but cannot connect.

the broadband connection was first tested in my system, so may be the mac address of my system is registered in ISP. but i really cannot digest that because ISP is assigning dchp ip to it's clients.

Contact your ISP and explain the situation. If it's a MAC assignment, they'll be able to reset that for you.

the broadband connection was first tested in my system, so may be the mac address of my system is registered in ISP. but i really cannot digest that because ISP is assigning dchp ip to it's clients.

Trust us, this is not unusual. In fact, that's exactly how my ISP operates. I get my external IP from them via their DHCP server. It's registered to the MAC of whatever device is connected to it. If I unplug my router and plug any other device in, it won't get an IP address.

I would recommend buying a SOHO router to put between you and the internet. This way you can connect/disconnect multiple devices without this issue arising again.

A while back I had to get a new modem from my provider. Initially they had provided me with a combination unit (ie: modem/router/wireless AP all in one) and the wireless side of it was failing. Since my wife uses wifi, I had to replace it.

I asked them for just a modem and purchased my own router. Knowing in advance about my ISP registering my MAC, I wrote down the MAC of my old device before replacing it. When I plugged the internet into my new router it didn't work because of the different MAC. However, I bought a router that allowed me to spoof the MAC of the external interface so I simply entered the MAC of the old device into that field and voila, the new router got an IP and worked.

thank you @Curt R for your valuable information and advice. but i wanna inform that i discard the mac address possibility because i've tested the connection in about 7 pcs of my network and it works in 4 of them and doesn't work in 3 of them. currently the connection scenario is that the modem is connected to hub and then some pcs are connected to hub and some to modem ethernet port. i have an internal dhcp server, dns, active directory, nating, etc configured by windows server 2003.

it is quite unsual, 2 working pcs are not directly connected to modem ethernet port yet it works where as 2 works only if it is directly connected to the modem. and above all i don't understand this broadband technology. any system will have only one NIC by default but when the broadband is connected, i see two ip being assigned and looks like two NIC is there in the pc.

whateva, i've planned to buy a router and a switch but i've a question in mind. usually this broadband technology requires user to dial when ever internet connectivity is required. now if the modem is connected to router, will the router do that dialing work on its own? and please remember that the isp has not assigned me a static ip for this purpose, the ips are dynamic from their server.

i want the router to NAT aswell as perform the dialing and fetch internet connection before it goes to switch. so that the network users are connected to internet as soon as their systems are started.

along with it, i wanna know which router is best in my case with fibre optic broadband and with LST402E modem. switch i will buy the D'link one with 16 ports. i would love if the router would have wifi capabilities also because i've three laptops which can use the wifi connection.

Not to be rude but, you REALLY need to try using some capital letters when you're typing. Not doing so looks unprofessional and well, makes you look semi-literate. It's also a lot harder to read. You're not texting on a smart phone here.

but i wanna inform that i discard the mac address possibility because i've tested the connection in about 7 pcs of my network and it works in 4 of them and doesn't work in 3 of them.

If I'm reading this right, you don't think it's possible that it's a MAC registration thing. Trust me on this, call your ISP and ask them. It shouldn't take more than 5 or 10 minutes of your time and may save you a lot more typing.

My ISP registers 3 MAC's. Since I've used all of my 3 MAC registrations I have a couple choices if I want to connect a different device to my modem.
1) Spoof the MAC of an existing registration (which I did with my new router)
2) Call my ISP and have them remove one, two, or all three registrations
3) Figure out where on their website within my account with them that I can go delete those registrations myself.

Who's to say your ISP doesn't register 4 MAC's. You won't know unless you call them.

Just FYI, I'm not reading beyond what I quoted above. Your lack of capitalization makes my head hurt. If you'd like me to read any more of what you post, start using your shift key for it's intended purpose.

You have a ip addressing problem since you don't have a router doing nat.

"any system will have only one NIC by default but when the broadband is connected, i see two ip being assigned and looks like two NIC is there in the pc."

Post the results of a ipconfig /all from a pc with this double ip assignment for us to review.

The first thing you should do is disable the wireless adapter. If you're not using it, shut it down. I've run into many instances where having both the wired and wireless interfaces running caused problems for Windows. Typically it's only with the desktop OS's (XP, Win 7) and not the server, but it's still a good idea to shut it down and rule that out as causing you issues.

Your Local Area Connection adapter shows the following:

IPv4 Address. . . . . . . . . . . : 192.168.0.19(Preferred)
Default Gateway . . . . . . . . . : 192.168.0.1
DHCP Server . . . . . . . . . . . : 192.168.0.1
DNS Servers . . . . . . . . . . . : 192.168.0.1

If this computer is your server, what device is 192.168.0.1?

If this is your server and you have your internet connected directly to it as it appears, your issue is that the default gateway and DNS addresses are sending your traffic to the wrong place.

If this were me, I'd spend the money (less than $100) and buy a decent SOHO router and I would put it between my LAN and the internet. I would connect my server and my clients to the router and if you have more than 4 clients, I would get a switch with enough ports to accommodate your clients and connect it to the LAN port on the router and the clients to the switch.

I would make my router's LAN port 192.168.0.1 and the Server 192.168.0.2 and I would let all other clients get their TCP/IP settings from the routers DHCP server.

Using a SOHO router instead of your server to deal with NAT/DHCP will reduce the load on the server itself and will allow you to shut off the second NIC on this server.

Did you ever call your ISP and ask about MAC registration?

Ok, FYI 192.168.0.1 is the internal server with Windows 2003 Server installed. Infact i want to NAT the broadband network from ISP with mine using the NAT capability of the Windows Server 2003 and distribute the internet from my server to the internal LAN users.

The problem is that we have to create a broadband connection interface in the server and dial in order to get the internet connection. Now, when i connect one of the network adapter of the Windows Server machine to the ethernet port of the modem, i should get an IP from the ISP. But in my case the adapter cannot get an IP. Without the IP the dialling of the broadband will not be successful.

Whatever, now I want to buy a router and a switch but still I am skeptic whether the router will dial the broadband connection automatically. I have used broadband connection before but not like the one now which has to be dialled. My earlier ISP's line was directly connected to my server and they had assigned me a static ip for me to NAT mine and their network. Now this time, my current ISP assigns ip dynamically as well as the internet connection has to be dialled everytime we want to connect to internet. If the dialling of the broadband connection is taken care off by the router then i have no problem spending some bugs for the equipment else its not worth buying if it doesn't serve my purpose.

And lastly, if i go for a router then which one is best for me? I want to have a router which has wifi capabilities also.

Please note that the dialling system of this broadband connection is the main issue here. If i buy a router, will it dial the broadband connection on its own and connect me to the ISP network to get the internet connection? If that is done, then my problem is solved, my only work would be to go for a router and distribute the internet connection through it.

Infact, i found this broadband service same as the phone line dial-up connection. To get the connection i have to dial. This is not what i want, I want a connection which needs no dialing and can be distributed without having to dial, so that the internet connection is there 24/7.

Sorry i don't know how to make diagrams. You can just think that i have a hub and all my internal pcs are connected to hub including the windows server 2003 machine with ip 192.168.0.1(static). The windows server 2003 machine assigns dhcp to all other xp and windows 7 machine in my network.

Now recently, after the introduction of the broadband, the 2nd NIC of windows server 2003 is connected to the modem ethernet port. This is where the problem starts, the NIC connected to the modem should get an ip from ISP but its not getting. Thats the problem.

And as i said the broadband works in dialing system, i want the router to take care of this dailing issue if i buy the router. I think the dialing thing is called PPPoE. Please guide me!

Ok to give you and update, I brought a router TL-WR340G and tested, yet its not working. I am able to connect to the router via cable or wi-fi, but i don't get the internet connection.

The router supports PPPoE but when i try to configure the router with the PPPoE, the configuration fails. My username and password is verymuch correct. If i configure the router with dynamic ip, the router configuration is successful. But, i am not able to get the internet connection even if i am connected to the router.

Now, i wanna know why the PPPoE configuration fails? My ISP has said that sharing of the broadband is not possible but i ignored them thinking they would be wrong. Are they right to say that my broadband cannot be shared?

Now recently, after the introduction of the broadband, the 2nd NIC of windows server 2003 is connected to the modem ethernet port.

I've said this to you at least once before, and I'm going to say it again, do yourself a favor and buy a SOHO Router and put it between your LAN and the internet. You can still do the DHCP from your server if you choose but I wouldn't. I would do DHCP from the router. Unless of course you have a windows active directory integrated domain in which case it would probably be simpler for you to leave DHCP on the server.

This is where the problem starts, the NIC connected to the modem should get an ip from ISP but its not getting. Thats the problem.

And this is the very last time I'm saying this.

Chances are this is happening because your ISP registers MAC addresses and you're only allowed, one, two, three, or maybe even four. The ONLY way to find out is to call your ISP and talk to them about this. You still haven't called and I've told you to do so several times and I'm done talking about this to you. I can't help you if you refuse to do what I tell you to do.

Here's the very last thing I'm going to say to you.

I recommend you hire a qualified professional computer consultant to come fix you up. You're not capabale of getting this working on your own and you obviously don't think my advice is worth anything so I'm done talking to you.

Did you clone a working workstation's mac address to the wan port of the router? You should.

Your server config is wrong. You need two network cards in the server. You engage RRAS between the two nics. One nic is connected to the router. The other to the hub. All pcs connect to the hub not the router.

That would be incorrect.

Once again nic1 in server goes to router. Nic2 goes to hub. All pcs connect to hub and not the router. Hub is not connected to the router.

Sounds like you need to go back to your server book and review the proper setup of dns server [and its forwarders - hint hint] as well as the correct config for RRAS.

You are right, but remember, i want the PPPoE to configure through router and then connect the router to the hub so that all the computers in the LAN gets the internet. With the introduction of the router, i think the 2nd NIC of the server computer is of no use because the PPPoE connection should be taken care off by the router.

The concept is that I want the server computer to act as dhcp and file server only. The router's work is to NAT and provide internet to my LAN.

You must first determine what pc/laptop you first used to setup the PPPoE connection. That is the one to use for cloning the mac address to the router. You would logon to the router via the gateway ip. You would not use the setup cd. Clone/spoof the mac address would be found on the wan setup page in the router.
