Preferred Solution: Can you get DHCP info from the modem software even when the DHCP server is down

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I am trying to set up a DHCP server, I need to know what other services are required along with DHCP example: WINS, DNS, ,etc.. Also what protocols to install besides TCP/IP. I tried NetBEUI and was able to log into the server with my laptop and a crossover cable, but when I use only TCP/IP it says there is no domain to verify my log in. But when I was able to log in the IP address was the same on every login, it was something like 169.???.???.???. Also when connecting a hub do I need to have some kind of serial connection from the hub to the server or just patch cables from the hub to the NIC cards. Thanks for the help.

A:{Advice Offered} - DHCP server & Hub info

I see Reuel hasn't gotten to this yet, so I'll give it a shot...
With my DHCP Server (PDC), I've got it with WINS, pulling the info from another site. Put WINS on there so you can resolve the computer names from the IP's...That way the only protocol you need is TCP/IP. If you're not getting your WINS info from somewhere else, you'll need to set up your lmhosts file. Put those settings on your server, add the new computer to your domain, then log on. If you've still got that 169.xxx.xxx.xxx do an ipconfig /release, then /renew from the command prompt, and I suppose that should be that.
As far as the connecting with the hub, I believe you can just run the patch cables from the NICs to it, if there is a switch for "normal" on the hub, go to that, not "uplink". Then again, I could just be talking out of my arse here.
But I honestly think the best thing to do is to try whatever Reuel has to offer...He's the man, in case you didn't know.

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.

I've tried adding a DWORD entry 'IPAutoconfigurationEnabled' = 0, also tried deleting the 2 values.
Tried setting the IP manually to 192.168.2.6 - limited connectivity goes away but I get no internet connection from the router nor file sharing.

Any help please?

Hi,
My old hard disk was dead so bought a new hard disk drive of 500gb, when i tried to install windows xp on the new hard disk the cd didn't boot as it used to do first, it gives out an error during boot "PXE-E51: No DHCP or proxy DHCP offers were received please enter bootable device and press any key". Thanks in advance.

A:PXE-E51: No DHCP or proxy DHCP offers were received

Any message such as this referencing 'PXE" are likely indications that you need to adjust the boot device settings in the BIOS.  The message indicates that the system is currently trying to boot via network, rather than boot to an optical drive or a hard drive.
 
If you want to boot from a CD to install XP, then the first boot option in the BIOS must be changed to an optical drive.
 
If you want to boot from the hard drive, then the first boot device should be changed to reflect the hard drive as the first option.
 
What makes you think that your old hard drive was dead?
 
These PXE errors are often the result of the fact that the CMOS battery is dying or is dead and needs to be replaced.  Since this is a vital but cheap item easily obtained, this is not a serious problem.

How can I get this bridged internet connection to pass on the dhcp server information to the device?

This seems like it would be a simple answer from a techie.. The network cable is passing the world wide web,(google .etc.) but is not passing the dns server information.

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.

Here is my current configuration:

We have 7MB/768K DSL Business dynamic IP connection.
Anywhere from 10-20 simultaneous users.
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.

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

Are there any low cost solutions that would provide faster performance for the users?

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?

A friend of mine asked me for some help connecting his new cable modem & router to his server. Here is his e-mail to me,

So we got this cable modem and router installed for internet access and the
dudes who installed it were able to get the server (or his laptop)
connected, but not any of the workstations, When he changed the server
settings to enable it to connect to the internet, none of the workstations
could then even connect to the server.
THe guy claimed that the issue is that we are running DCHP with dynamic
addressing and if we simply (hah!) changed to a 10.1 static IP addressing
system then all would be fine!
Does this make any sense to you?

Some things you will need to know, the server is NT4.0 with sp6. The workstations, about 50, are a combo of 95/98 machines. All connecting using DHCP as previously stated.

 

A:{Advice Offered} - Cable Modem with DHCP?

Well, generally speaking, you need to set the Gateway on the workstations to the IP address of the Router.

Assuming the router can't do you DHCP for you. If it can, that would be best - just let it assign your IP, Gateway, and DNS across the network.

What kind of router is it? Most of them support this. Obviously you would need to turn off DHCP on your server for this, but you don't need two DHCP servers, do you?

What do you mean "recently moved my modem"?

Two questions
1) Did you change ISPs?
2) Has the hardware connected to your modem changed (e.g. did you add a router between your computer and the modem?) as the modem "sees" the MAC address of the first device connected to it. And sometimes won't connect to any other device with a different MAC address

A:DHCP Server behind a NAT Router

it's actually a routing issue; if you can add proper routing from the router to the server,
it will all work.

HOWEVER, it would be far easier to just place all systems in the same subnet.

You may be thinking at first that this would be a typical 169.x.x.x thing, but it is far from. I've tried doing the winsock and tcp/ip fixes and nothing seems to work. There are two PC's currently on my topology, and my PC works perfectly fine. So it is apparent that the other computer has a phony DHCP server hosted locally on the other computer.

The Router: 192.168.1.1
Router's DHCP range: 192.168.1.100-49
Offending computer's IP: 192.168.16.129 !!!???

I have run the Smitfraud fix and in the log file it returns some pretty interesting entries regarding this 192.168.16.254 DHCP server. I tried deleting the offending registry keys listed in the log file, but to no avail.

Tried disabling the DHCP service, tried assigning statically, nada.

So it would appear that it has been hijacked, but i have no idea how to remedy the situation. Any ideas?

Relevancy 86.43%

Our DHCP server has a scope of x.x.x.50 to x.x.x.150 with a few reservations added, but the reservations all fall outside that scope. It's using a /16 subnet mask so the reserved IP's on on the same subnet. The DHCP server is the one you get with Win2k3 server standard edition.

QUESTION: Are the reservations actually doing anything ?

I'm sure the answer is an obvious "NO" but I just want to hear someone else say it.

I just got Cox cable and it hasn't been working right.

I have a netgear WG602 wireless access point. I can connect to it but it has limited or no connectivity. Repairing the connection doesn't work and doesn't give me an IP.

I connected the ethernet cable directly to my laptop and it didn't work at all. I called them and it worked by directly connecting, but the wireless still didn't work.

Then I messed with wireless settings to try to connect, and I finally got online but my ip is 70.x.x.x, the apparent IP for all Cox subscribers.

But I got that 70.x.x.x through my router instead of a 192.x.x.x so I have no idea why it's doing that. It's really weird and I still can't get a dynamic IP.

Hi Geeks!
I want to backup my DHCP server. I want to make sure that if my DHCP server goes down for some reason there is a server at standby that can come and takeover as a DHCP server and start leasing the addresses.
Or if i can add an additional DHCP server.
My Current DHCP Server is Windows 2000 Professional.
Is there any way that i can create a DHCP backup server as in case of Active Directory...

Kindly let me know if anyone has any sort of solution

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.

kcplayboi_26 said:

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.

It would be helpful if you could tell us how you connect to the Internet. Are you on cable, DSL, dialup? We also need to know who your ISP is, what your brand and model of modem are, etc. Without more information, there isn't any way to resolve your problem.

A:unable to contact DHCP server

Try This

Disable the XP firewall and try again. If it works, set it back up but as part of a LAN.
From the command prompt, ping 127.0.0.1 and see if you get OKs back. That means your network adapter is probably Ok.
Next, run the Wireless Network Setup and see if it recognizes the network adapter and can detect your LAN. Unless you've changed your WEP/WPA passwords recently this should work.
Run a virus scan and see if you picked up a bug.

Let me know how it goes

I've been trying (in vain) to connect a USB Wireless device to be able to use it off my wireless network. I have (2) other laptops and (1) other desktop connecting to the router with no issues.

For some reason, this old desktop keeps installing an Ethernet device (probably on the MB) and is automatically Configuring the IP address to that instead of the USB wireless device.

I've tried uninstalling the Ethernet device but it comes right back after I do a reboot. Even when I disable it, I still can not connect with my Wireless device.

Hi,

I moved a Win2K machine from a domain to a workgroup which uses a Linksys cable router as its DHCP server. I'm having trouble making the machine to pick up the new DHCP server. It thinks it cannot locate the DHCP service so it keeps getting assigned the APIPA (169.254.x.x) address. BTW, back in the domain, this machine was assigned a static IP address through client reservation because it was running a service. Does anyone have an idea? Thanks.

Have you changed all the domain settings so that its not still looking for the domain when it starts up? If the machine's name is part of a FQDN get rid of the extensions so that it has an "old fashioned" single name.

Also clear out all of the settings for DNS that may have been set, make them all blank in case the system is trying to find it that way.

Remove any other network protocols that are installed except TCP/IP.

Hi all I have two routers One is a Linksys WRG G with the Tomato firmware flashed router filter web as one another Using DHCP server, as The other is a PC running the IPCop software Either would work fine on their own as a router I m wanting to use them both though Using one router as DHCP server, another as web filter because each offers different features Tomato has good QoS features but IPCop has good URL filtering My current setup is this IPCop is Tomato is Tomato is the DHCP server and uses as the default gateway So all traffic gets passed through IPCop it appears What I would like to have is ONLY web traffic Using one router as DHCP server, another as web filter going through IPCop I guess I could do this by using it as a proxy server and manually entering in the proxy settings on each computer on the network That isn t practical though so I m trying to think of a better way I have a hunch there s a fairly simple solution to this but I can t quite peg it The goal is this Have the Tomato router be the real quot router quot -- DHCP server port forwarding et cetera but force ALL web traffic and ONLY web traffic through IPCop Any suggestions Thanks nbsp

I got a new desktop loaded with Microsoft Vista.

When I couldn't connect to my router (at home) I tried ipconfig /renew /reliease commands and got the following message:

"Unable to contact your DHCP server".

I brought my PC to work and it connected fine to the network there.

At home I use the modem/router provided by Verizon (FIOS). I tried several ethernet cables - so I am pretty sure it is not the cable.

BTW, other pc's at home are connected to the router, so the router is OK.

Any help is appreciated.

A:unable to connect to DHCP server

Check the setting on your Router which served as your DHCP as well. Make sure that the Router provides enough IP addresses for your home network.

Maybe only the one computer is allowed to connect and you have to call the provider to "reset" the connection or to register another computer to allow it to connect.

Maybe it is computer(s), but I would suspect a router.

Don't know how to track either down other than by walking around and looking for a router. Or with a Wi-Fi detector walk around looking for a wireless network that shouldn't be there. You can use a laptop as a Wi-Fi detector with utilities such as the Xirrus Wi-Fi Inspector (or gadget).

Or maybe Advanced IP Scanner (or similar) would help. Scan for one of the IP ranges and then for the other. If you find a router that shouldn't be there, or a computer on both networks, maybe that would give a clue.

A:Cisco Router DHCP Server

It's been a while since I have configured DHCP services on a router or switch. But from what I remember, the router or switch will know which interface to answer on based on the scope(s) you have defined in the DHCP configuration. Say you have two interfaces with one on 192.168.0.0/24 and another on 10.0.0.0/24. If you define a DHCP scope to hand out addresses in the range from 192.168.0.10 to 50, the router/switch will know to answer DHCP requests on the interface configured on the 192.168.0.0/24 subnet.

I am receiving event id 1007 from source DHCP on my Domain Controller which is causing loss of routing and access to network resources. From initial research it appears to be caused by one of the network cards receiving an auto configuration IP address in the 169.254 range. This is causing users to lose access to the Internet, which is not good.

Anyone any ideas what could be causing this? It has only recently started happening. The DHCP range has 31% free so it should not be due to IP address conflicts?

Grateful for advice if anyone has come across this.

I was working on a XP SP2 computer yesterday and was unable to establish a valid IP address. I was able to get a valid IP address with another XP computer so I know it's not the service itself but the computer. I tried running winsock fix, removed Norton Internet Security to make sure it wasn't creating any conflicts, installed a Usb-to-Ethernet adapter--I even restored the computer to a month prior to no avail. The weird thing is, I'm able to get the initial local IP of the cable modem itself which is a good sign but when it tries to release the local IP for one assigned by the DHCP server, I get all 0's or a 169 IP. Any ideas on what is happening?

A:DHCP server not leasing IP addresses

You have a public ip address on one machine.

Make sure you have the modem plugged into the router wan port, then the computers plugged into the remaining ports, usually labeled 1-4.

Then try resetting all of the routers, modems and pcs. Modem first, then router, then the pc's

Hi surffishermanca, and welcome to TSG.

Some ISPs (like SBC/ATT) configure the DHCP server on the modem to only give out a limit of one IP address, unless you sign up for some type of home networking plan. Try power cycling the modem when you switch computers.

EDIT: Thank you very much for all the details. Most people here would rather sift through bits of extra data than not having enough.

Quick question,

Is there a reliable way to setup a secure dedicated webmail server at my home using a dedicated computer and a DHCP cable line (15m-D,2m-U)? If so, what is the difficulty level of this on a 1-5 scale (5 - able to write your own drivers, 1 - can hook up a computer)?

Also, where is a good place to read about how large scale network infrastructure and management works? I'd really like to learn about how server grade routers, firewalls and the like work. The most I know is to connect to xx.xx.xx.xx (ip) to configure my linksys router. I appreciate all your direction and thought (and time).

Safemode with networking
with a cable connected from PC to router
check the cable - see if there is a light on the router associated with the cable port used , also check if you have a green/yellow light on the PC LAN port (some PCs do not have any lights on the LAN port - so ignore)
- try safemode with networking (sometimes wireless does not work with safemode )
as the PC starts keep tapping F8 - a menu appears - choose
safemode with networking - see if that works

have you changed the cable at all ?

What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, kaspersky or Mcafee or any free security suites like zonealarm, AVG , Webroot etc

I've read a few of the forums from people who were having the same trouble but found no forum and answers for a user who has D-link 802.11g/2.4GHz.

I'm on a friends laptop at the moment.
I don't have any floppy disks or CD's to copy my desktops information, but need to figure out how to fix this problem.
if anyone could help me your really nice and i appreciate any information <3

Is the number of DHCP pools limited only by the amount of RAM or is there a set limit you can have depending on the router model?
