Hi All,
Ok i have a problem, I have a router and a network of hubs serving internet to a building. Now when i connect a windows 2003 server it messes up the internet connection for the whole building. Any solution?
A detailed map of your network topology would really help a lot in troubleshooting your issue. Make sure you include make and model for all network devices (routers, switches etc). Insure you include IP address for all switches and routers and show what's providing DHCP (if you're using it) and what the scope is.
Check Event Viewer on the 2003 server for errors relating to the failure and also on at least one of the clients.

The network setup is as following:
Router connected to ISP and network cable from Router (dhcp enabled) into hub/network rack, from there a connection to each office. Now in the office there is a single network cable which if connected to a computer provides internet and networking. Now that single wire in office goes to a switch and from switch into computers, now i want to attach a server which has a database. All computers are dell and so is the server.
To attach the server, i manually configure the IP that was given when set to automatic. It works ok for sometime but then the whole internet just shuts down and i have been told it is due to the server.

Ok, now how about telling us the make and model of the router and the switch(es).
What is the DHCP scope?
What is the server's IP?
Oh and as far as the IP addresses go, if you're not using private IP's, just the first two octets will do. You don't want to be posting routable IP's on here.

He can't tell you the server's IP address. That would be a security violation. Besides what will it do for you. All he needs is the first couple octets of his subnets to ensure that they are being routed right.
Now for the problem. Windows Server will mess up the Internet if you have not included your servers IP in your DNS forwarder because your computers will run to your server for DNS resolution and it will not have the answers because your edge router or DNS forwarder has not updated the DNS on it.
Do an IPconfig/all on one of your workstations that is not working (Redact IPs for security) and you will probably see that they are running to that server for DNS.

I am not sure about the router since it is in the building managements communication room and we do not have access to it but the switch rack has NETGEAR hubs/switches.
The server is a DELL T100 and the work stations are DELL E520.
The IP's are 217.169.***.***
and the subnet mask is 255.255.255.128
Hope this helps

" i manually configure the IP that was given when set to automatic."
You can't do that. Once the lease is up it can get assigned to someone or something else. Then you have a ip conflict which disables both devices.
Given your situation you should leave it at getting a dhcp address.
Being that you are in your own office but the building is sharing internet all in the same subnet, you have no privacy/security.
I would talk to the building supervisor and see about you getting your own SOHO router that your office plugs into. It in turn would connect to the shared internet network. It would be located in whatever closet your office is wired to for the switch/hub connection.
Then you could do your own internal ip plan and give your server a static ip as desired.

ahhh i see,
someone mentioned a router with a WAN port? is that it?
The RJ45 coming from the port in the office connects to the WAN port of the Router, then the computers go on its 4-port switch and i was also told the ip' in this case will be 192.168.1.***
If this is the right, i'll go and get this router :)

Didn't quite read my whole post did you. Here's a refresher.................and I quote:
"Oh and as far as the IP addresses go, if you're not using private IP's, just the first two octets will do. You don't want to be posting routable IP's on here."
No worries, I've been guilty of the same thing often enough that I know the taste of my own feet quite well.
In fact, I should have ask for the complete output of an ipconfig /all (with the last two octets x'd out of course) to see that he had the right IP addresses for the important stuff like gateway and DNS.
I agree with everything wanderer said in his response. I wonder though if you really need the building manager's permission to put a SOHO router between your network and theirs though. I would talk to the building manager and if he's ok with it, have him assign you a static IP address from his pool that is either reserved in DHCP or outside the DHCP Scope so it can't conflict with any other IP's in that network. Then as wanderer said, you can do whatever you want internally without worry.

Curt, Unfortunately, there is no network administrator in the building, just a lady who is the centre manager. Infact i am the only person in the building who is interested in these things hence i was assigned to troubleshoot this problem. I don't know much about networks either.
I do not have access to the machines but if config /all will help, i can get a screenshot

That would be ipconfig /all
Yes a router with private ip of 192.168.x.x is the way to go.
Problem is you don't want this in your office. You want to use the network cabling that is already in your office.
Hence the particulars of my post concerning closet access.

unfortunately they will not allow into the communication room.
The rj45 socket in the office can go into the router and there onwards my own cabling around the office hopefully will allow me to have a server and internet both at the same time right?
The ipconfig command will go on the client or server?

If they do not allow you to put it in your "communication room" then you can simply put the router in your server room. The question is where do all of your workstation's network lines terminate or get connected to the internet. Are they in the communications room or do they terminate in your server room?
If in your Server room then simply setup the router there.

ace this is an office. No server room.
Adeel you have no choice but to use one of the incoming lines for the router and then connect all of your cables to it instead of the wall outlets.

Really appreciate all the help you guys are giving :)
I am going down the cable router way so i was looking for a cheap one that will do the job, and i saw the Netgear RP614, is this the right router i should be looking at?
If there any other recommendation, would love to hear :)
Thanks once again, hopefully once i have it, i will update with the progress :)
