DHCP Server using (1) Network card

Q: DHCP Server using (1) Network card

Hello Everyone,

We our setting up a Training Company to assist unemployed IT people in the Silicon Valley area of California. Our group is very small and having a hard time even getting our network here started. Here is the problem: We have Windows 2003 Server Enterprise 180-day usage disc (from a book we bought to learn). We have 5 static IP addresses leased from DSL carrier. They are for example: 65.123.141.10 thru 65.123.141.14 with a gateway of 65.123.141.9 [these are only IP numbers used for example to prevent hacking] my subnet mask is 255.255.255.248 We tried and tried for 2 weeks now and still can not get the complete network to work. We need: Step1.) The server to be secure with a firewall (but willing to forgo that and add later) Step2.) the server to issue Ip addresses from a pool of 192.168.0.10 thru 12 to 3 workstations running XP(we decided to make the server 192.168.0.5, subnet mask is 255.255.255.0 and gateway 192.168.0.1 Step3.) Have access to the internet on all workstations and the server too. All we have succeeded to do is get the dhcp to issue out addressses to the workstations and even that i think we got lucky. We think the problem is somewhere you need to tell the (maybe iprouting?) setup that the Public ip address is the 65.123.141.10 and gateway, subnet info and to route to the server PRIVATE ip address 192.168.0.5
Thank you for any help. We are on very limited funds here and appreciate any help. My number is 925-984-9907 if you wish to call. We will be adding a feature later to our support group to help people find a IT job as well if you need our help its FREE if you help us out. Thats the best we can offer back right now!

The Server went down - it is at shop for repairs. Meanwhile everyone can acecss internet fine - router is the DHCP and DNS server. However today one computer on the network is getting an APIPA address and can't ping the default gateway or any other computers on the network. Loopback ping works and device manager indicates network card is working correctly. Checked cables. Uninstalled and reinstalled network card. Rebooted several time. Anyone have any idea what to try next? All other computers on the network are accessing the internet just fine.

I am running windows xp on a dell inspiron 4150 with a built in wireless card. My wireless was working fine until windows prompted me to reboot due to windows update. It stopped working after that. It is telling me that no ip address can be found and when I ipconfiged it with renew and all it still could not find it. It gave me an error message that says cannot connect to DHCP server.
Any help will be appreciated.
Thank you,
 

A:Network could not connect to DHCP server

Nothing really comes to mind, but if you're using Window's Wireless Zero Configuration maybe you need to reconfigure your wireless connection; especially if your network is protected with encryption.

I use the utilities from my wireless cards' manufacturers to connect to my WPA protectecd network and had no trouble today after the same reboot (two notebooks). Well, same reboot if you're talking about the critical update released yesterday.

Hi folks,

As I've said in the title, I'm looking to make a network with two routers but only having DHCP enabled on the secondary router.

Before I go any further I must ask: I have an Arris GT840A (sigh) as the primary ISP required modem. I'm currently connecting via wifi and sometimes have pings to the router coming back in the 1 - 20ms range for extended periods and it's decent. Other times I get a huge range of different ping times, often in the 300ms - 6,000ms range and sometimes even dropped.

Is disabling the DHCP server on the modem and relegating all local networking duties to my WRT54GV2 likely to alleviate this problem, or does this simply boil down to I'm screwed because I have to use this Arris modem?

Moving on with the primary question, here is my current setup:

Router 1: Arris GT840A
WAN IP: Dynamic / ISP assigned
LAN IP: 192.168.0.1
DHCP: Enabled
192.168.0.2 - 50

Router 2: WRT54GV2 (Connected to router 1 via WAN port)
WAN IP: 192.168.0.51
LAN IP: 192.168.1.1
DHCP: Enabled
192.168.1.2 - 50

With my current setup I have been able to ping both router 1 and 2 via wifi, but I have not been able to ping or connect to the internet at large. I have read a couple of different how-to's and other forum answers and feel like this is how I'm supposed to be setting it up, but it's still not working. Something that concerns me about this attempted setup is that it still is using DHCP from the Arris modem / router, and I'm r... Read more

so I have two router now,
router A handles TV and Internet (PS3 and A labtop)
router B handles wired and wireless internet ( I have it MAC enable, so ppl won't be able to access my wireless network from outside)

how should I setup so PS3 can access movies from computers behind router B ?

EDIT: I tried to make them within the same subnet

router A : 192.168.0.254 (DHCP 65-99)
router B : 192.168.0.1 (DHCP 100-120)

when I connect router A with B by connect ethernet cable by LAN, Router A is able to ping a computer behind router A, but the computer can't ping router A.

Hello. I just moved to Auckland, NZ from the USA to go to school at the university here, and am having a problem connecting to the internet in the university residence hall in which I am living.
Wifi is not available in the residence halls, so we need to use an Ethernet cable. When I plug in my computer, the network adapter icon says “Identifying...” for a while then settles on “Unidentified Network” with no internet access, the IP is 169.x.x.x
When I try to release and renew the IP, it says “unable to contact your DHCP server, request has timed out"
I've tried multiple Ethernet cables, both brand new.
I tried connecting to a port in a friend's room in the same building, and even in a classroom on campus, and both had the same result.
Naturally after all that I assumed my NIC somehow died overnight while I traveled here, so I went to a computer repair shop expecting to have some hardware replaced, but we plugged it in there and it worked immediately so they weren't sure what to tell me.
I've gone through pages of old threads at this forum and others like it, trying solutions but having no luck.
I've power cycled my computer, obviously I can't power cycle the whole network as it's for 200 people, but the IT people here have tried resetting it for me on their end as best they can.

When logging onto the company network via a RAS server, the DHCP active leases is not being updated with the IP address assigned to me. This is the case both when the RAS server is configured to give an IP address from a fixed pool, or when configured to obtain IP address from DHCP. As a result, I'm experiencing problems if an existing lan device has an IP address assigned and the dialed in device grabs that address. Whats going on ?
 

A:{Solved} - DHCP active leases not being updated when dialing into network via RAS server

Greetings

There should be a clear distinction between the IP adresses available for the network, and those available for the Dial up users. Do not make them part of the same IP group.

The reason is that Dial-up IP addresses should have a lease time of a few hours, and the LAN lease time should be that of a few days. This is obviously not compatible, so they need to be seperate.

Hope this helps

I warmly welcome

I have a problem with configuring network cards

WIFI comes nicely with DHCP pool 192.168.0 .*
but

I have a virtual network adapter "Microsoft Loopback Adapter"
in it I have to have a static IP address 2.0.0.5
and set it manually (IPv4)

the problem is that the WiFi card is still changing my IP address of the virtual card

how to prevent it?

I wanted to wifi card automatically collects the IP address
but did not interfere in the virtual adapter's IP

A:Wifi DHCP - the second network card on a fixed IP

I quote (from ):






Quote:
Microsoft Loopback Adapter is a dummy network card, no hardware is involved. It is used as a testing tool for a virtual network environment where network access is not available. Also, you must use the Loopback adapter if there are conflicts with a network adapter or with a network adapter driver. You can bind network clients, protocols, and other network configuration items to the Loopback adapter, and you can install the network adapter driver or network adapter later while retaining the network configuration information.


Given that, there is no way your wi-fi card can "change" the IP address of your fake network adapter. If you set a static IP for ANY adapter, it WILL stay that way, regardless if one adapter is set to release and renew based on DHCP and one is not.

I even tried it myself. I installed the loopback adapter, set an IP and all that for it, released ALL DHCP'd IPs and renewed them. the static IP for the loopback adapter didn't change.

Take a look at your settings again, make sure you didn't miss something.

I have a problem with my pc randomly locking up and having to be rebooted. I believe it has to do with the wireless card accessing my network, but I can’t figure out how to troubleshoot it. (If this is the wrong forum, please let me know!)

I have a desktop, two laptops, and a printer on a wireless network. All of them have been working fine. Then, about a month ago, I loaded a new game on my desktop, which worked entirely fine for roughly three weeks. Then last week, I tried setting up a server in the game. On my first attempt, it locked up my pc at the setup server stage, and I had to reboot. On my second attempt, I tried a slightly different configuration, and it created a local server and worked just fine.

Everything seemed okay for a couple of days, and then the game started to lag after a few minutes of play. After two or three more rounds of play, the lag was then accompanied by the pc locking up. Couldn't figure out why, so I stopped playing it.

Within a day or two, my desktop would randomly freeze without warning, with no clear connection to any specific application or time of day. This has continued to today. Sometimes the lock up is preceded by erratic behavior, such as the wireless keyboard freezing up though the companion wireless mouse will work (or vice versa) and an occasional USB connecting-then-disconnecting sound, though nothing had been touched. Sometimes the lock up is for 10 seconds or so. Most of the time, though, there are no warnings, and it ... Read more

2. Tested the internal NIC by pinging 127.0.0.1, loopback successful.
3. Uninstalled the LAN NIC and reinstalled it.
4. Removed all clients & protocols from the NIC's properties bar IPv4 and Microsoft Client for windows i.e. specifically removed IPv6.
5. Reset TCP/IP using netsh int ip reset c:\resetlog.txt.

Hello All, My company has been buying the M910Z systems since last year and I have noticed that the NIC card on these things will just randomly not pick up an IP address via DHCP when the PC is first powered on or when a network cable is unplugged. This doesnt happen everytime, but there are instances when the PCs go to sleep and the user is unable to connect back to the network due to the PC dropping the network connection. To resolve the issue, i have to either shut the PC down and then boot it back up or go into the control panel, diable/enable the NIC card in hopes for it to grab an IP. Is there a fix to this issue because im assuming its either a BIOS or NIC driver issue because I have isolated the issue down to these PCs and i wanted to see if the community could help me out here.

I'm running a simple network at home with a Linksys BEFSR41 router. I have two computers hooked up wired and a wireless router acting like an access point that I use for my laptop occasionally. Until this weekend I've been having no problems but I shut down the computers due to weather and now one of them is not able to communicate with any others on the network. The problem computer will get an address supplied to it by the router (DHCP server) but once it has it I cannot get any other connectivity. Of course this is hindering internet access on this computer. I can ping the loopback and assigned IP addresses w/o problems but when I ping the default gateway (router) and/or the other computer I get "Request timed out." I initially thought it was the NIC so I bought another one but still get the same issue. I've moved the cards to different PCI slots but no luck. I tested the cable running from the computer and the router but found no problems. I even tried resetting the TCP/IP stack but still didn't work. The computer in question is running WinXP SP2 with the original NIC being a Linksys LNE100TX and the new one being a D-Link DFE-530TX+.

Any clues on this? If more info is needed let me know--it's been a while since I've posted. Thanks in advance.

My WinXP Home PC won't connect properly (limited connectivity/no internet) via ethernet cable to my router (Belkin N150).

Ipconfig /all shows the IP address as 169.254.117.71 but this is determined by an entry in the registry at HLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{39A...} > 'DhcpIPAddress' - REG_SZ - 169.254.117.71. Also listed at 'IPAutoconfigurationAddress'. My laptop connects fine plugged into the same port getting it's IP automatically (192.168.2.2) and getting internet fine.

After much searching I can't figure out what's wrong.

QUESTION #1:
Is it better to use Win2000 Server DHCP or DHCP from my Netgear wireless router?

#1 BACKGROUND:
I am currently in the process of setting up a Win2000 server on my home network which consists of four other 2000/XP machines.
The server is going to be configured as a domain controller and will utilize the Active Directory.

Should I use the Win2000 Server DHCP or stick with my wireless router as the DHCP server? What are the advantages/disadvantages to both and which would be easier to maintain.

QUESTION #2
Is a 550mhz PIII with 256MB RAM fast enough to make a good home server running Win2000 server?

BACKGROUND #2
The server is going to have (2) 120GB Western Digital 7200rpm drives with 8MB cache for storage and a single 60GB Western Digital 7200rpm drive for the OS and few other applications.

The server's primary function is to serve as a media server with an approaching 10GB of MP3 and music video files which is continually going to grow. Disk contention is at a minimum since there are only four PC's on the network. There will also be a lot of digital photos stored on the server and will also serve as a place to perform backups from the other four networked PC's.
 

A:Win2000 Server DHCP or Router DHCP?

We have a similar setup in our office using Small Business Server, a public IP coming into our router with DHCP turned on, connected to a NIC in the internal DHCP server (which is also running ISA). A second NIC in the server bridges to the internal hub to provide DHCP services to the clients. This way we control port filtering in 2 places and with 2 levels of NAT taking place we feel secure. It may be overkill but we're concerned that EVERYONE is trying to hack into ISA and DHCP servers connected directly to public IP that this setup provides an added level of security.

So when I select it Windows comes up saying "you have selected the last remaining network card........" or something to that effect...

One Cisco 30 port switch feeding into one Linksys wireless router to provide local IP addresses to all the users for the one IP address to the world.

Hi skibizkit, and welcome to TSG.

skibizkit said:

... provide local IP addresses to all the users for the one IP address to the world.

It seems to me we have a huge bottleneck at the wireless router but we need it for the DHCP server in that router.Click to expand...

Sharing a single Public (world) IP address with multiple Private (local) IP addresses will require some type of router that supports NAT (Network Address Translation). Running a DHCP server on the router should only add a small amount of local bandwidth usage when a computer first connects to the router and gets assigned its private IP address by the DHCP server. The DHCP server is then out of the picture until another computer comes on line or the DHCP lease time (could be up several days) expires for each computer.

Is the speed bottleneck related to accessing the Internet through the DSL connection or exchanging data between computers (and servers) on the same local network?

Right now I have my server connected to a router and the router does the dhcp for me. I am thinking of putting a second nic in the server and using it for dhcp. If I have computers in the house that are not a part of my domain will I still be able to get online with them if they are connected to my switch? I guess to paraphrase myself I am asking can you use a server to route and not have everyone connected to the server in your domain?
 

A:Server DHCP or No

I'm not sure what DHCP has to do with routing... Are you trying to break your network into subnets?

You wouldn't need a second NIC to move DHCP to your server. If you want to move DHCP from your router to your server, just set up a new DHCP scope on the server and that's all that's required. Clients do not have to be part of the domain to get an address from a DHCP server.

Work in school with about 35 w98 clients and nt 4 server, recently had broadband installed so I had to change the IP address on the server as requested by broadband company then set up new dhcp scope for clients. Server reboots with new ip but cannot release and renew ip addresses on clients. (I had logged them all on ready.) Activated and reactiveted scope, changed ip back to orginal it all works but when you change it back to new settings clients can't see server, I gave one client a static address from the new range (an excluded number) and it logs on sweet as a nut - so I'm thinking dhcp problem. Also when I do IPconfig on server it gives 2 nic addresses for one mac address why?Any help would be appreciated!
 

A:nt server dhcp problems

Begining is the best solution!! hehe! So, You should do your DHCP as a new one, anyway, you were given a new IP, so it's absolutely new, isn't it!
Try mine!
Seperate DHCP from network, simply unplug the connector!
Stop DNS, delete your DHCP scope.
Uninstall, yes, uninstall you NIC!
NEXT! Do it in reverse!
Reinstall you NIC by restarting Windows! type cmd in Run command and ipconfig /all. How many NIC you have now? ( ofcourse, after you set the static IP, subnet...)
Restart DNS.
Create new DHCP scope, activevate,... ( Be sure you do it completely right).
Now, renew until DHCP work, ( Until you see the green light, you knew it).
Now, test DHCP in client by plug the connector!
Try this first!

I use a Verizon USB broadband modem attached to my Vista Home Premium desktop using ICS thru a wireless network for internet access and a home network. The desktop is linked to the wireless by CAT5 cable to a regular port on the router. We can then connect my wife's XP and my Linux laptops wirelessly. The router has DHCP disabled and all networked machines get their ip thru ICS from the desktop. This has worked well for 2 years. Suddenly I get limited connectivity from my NIC and a private ip (169.xxx.xx.xx). I looked at the services and found the DHCP server had been stopped. When I tried to restart it as a network service I got an error stating "the account specified for this service is different from other services running in the same process." If I change the logon to Local Service I can restart the service but it still will not give the NIC a valid ip. I have tried to use the diagnose repair option from network and sharing center but it fails as well. Anyone have a suggestion on how to fix this?

A:ICS and DHCP server not working

May or may not work but a winsock reset can be helpful in these sort of issues.

1)Click on the Start Button
2)Type "cmd" in the start search area
3)At the top of the menu you see cmd icon, right click it and left click "run as administrator".
4)DOS window, in this window type this minus the quotes " netsh winsock reset "
5)Hit enter key on your keyboard.
6)Restart the computer.
Give this a shot and see if it helps.

I would like to connect them all together and use the server for DHCP. How do I stop DHCP on the router and have the PC's on the network get the IP from the server. I have tried to turn off DHCP on the router, but then I can't connect to the internet.

Hello everyone!

I'm new to this site and I've searched for a topic related to my problem, but couldn't find anything.

I had Norton Internet Security 2005 installed on my computer, but when I added a new hardware item to it, I had to uninstall NIS and re-install it because it wouldn't work. After rebooting, I couldn't establish an intranet connection that did work on the comp before. I managed to find out that there is no default gateway on the LAN, because "no DHCP server was found". To be honest, I don't even know what this exactly means, but anyway. Here's what I tried so far, and didn't work:

1. Restore the default winsock settings, with the netsh winsock reset catalog command and with downloaded winsockfix programs too.

2. Try to renew the IP-address by right-clicking on the LAN settings.

3. Reset TCP/IP stack to installation defaults, with the netsh int ip reset reset.log command.

I've got Windows XP Sp2 and a D-Link DSL-360T modem/router, with ethernet.

I would appreciate any help, but please write it in an "advice for dummies" way, I'm quite a newbie with technical issues. Thanks in advance for your help!

If your PC is set to obtain an IP address automatically at boot up then it uses a DHCP broadcast system, this system sends a DHCP request via the network software through the network card and through the network cable out on to the network, if a DHCP server is available then it will reply and your PC will be given an IP address by the DHCP server,

DHCP servers can be a router, a PC running Internet Connection Sharing, or a PC running a DHCP client (such as on windows 2003 server).


If your PC cant find an DHCP server and you have it plugged into a DHCP server then either the cable is wrong or faulty, or the DHCP server is not seeing the PC.

Please post back saying what exactly you are trying to achieve.

I have reviewed the posts on DHCP but have had no luck in resolving my problem.
I have An NT 4 server as PDC running DHCP (The service is running)
2 NIC's in the server with static IP's 10.0.0.5 and 10.0.0.6
Scope with a rang 10.0.0.1 > 10.0.0.255
Sub net 255.255.255.0
Reserved 10.0.0.1 > 10.0.0.10
I did not config any other options
No Routers, WINS or DNS Just trying to get DHCP working first

Static IP on WIN98 clients work but when I select DHCP the client receives the "No Domain server found...and I get the windows 169.xxx.xxx.xxx default address.

As a test I have an ISDN box that acts as a DHCP when I hook it up to the network the clients do receive an IP from it. This box will not be on the network so I need to get DHCP running on the server.

Looking through the other posts, I can not find any problems with the setup or config.
