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

I need the IP address ,DNS and gateway address so on .Is it possibile to get it from the modems DHCP or do I need the ISP DHCP working?

I'm setting up are home network and getting connected to the internet but the internet connection is down .But is it possibile that I can get this from the modem. .

Like how does the computer talk to the modem and the modem talk to the DHCP server .I never had this problem before.

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/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

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.

A:Solved: Getting IP addr from DHCP but cannot ping DHCP server

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 but this is determined by an entry in the registry at HLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{39A...} > 'DhcpIPAddress' - REG_SZ - Also listed at 'IPAutoconfigurationAddress'. My laptop connects fine plugged into the same port getting it's IP automatically ( 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 - limited connectivity goes away but I get no internet connection from the router nor file sharing.

Any help please?

Is it better to use Win2000 Server DHCP or DHCP from my Netgear wireless router?

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.

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

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.

  I have several windows 8.1 machines connected to a private network.  The clients all obtain their first DHCP leases correctly and work well for a time. At some point after having been running for awhile, they get into a state where they start
ignoring the DHCP ACK messages from the DHCP server when they attempt to renew their leases (see attached pcap file).  They go on ignoring the responses to their DHCP Requests until they lose their IP addresses and then send a DHCP Discover and receive
a DHCP Offer.  At this point, they seem to accept their new address and move on until it is time to renew again, at which point they start ignoring their DHCP ACKs again and the cycle continues.  These machines will work for hours with no problems
whatsoever, but they all seem to experience this issue at some point every day.  When they get into the state where they are ignoring their DHCP acks, they will stay that way until they are rebooted.  Disabling and then re-enabling the adapter does
not seem to fix the issue.
 Does anyone have any idea what could be going on?  I'm pretty stumped at this point.

Thank you,

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.

Okay, I got a new client a few weeks ago. What a mess...anyway, they had bought a new Dell with SBS 2K3 on it, and for some reason they have a wired firewall (Linksys), a wireless router (Linksys) and a small switch. After examining the setup of the network, I found the wireless router giving out IP addresses in the 192.168.1.X range, the SBS being what it is, was going to be the DNS/DHCP/DC, on and on, etc. I turned off the DHCP on the wireless router. Yesterday they called and had a machine that I wasn't aware of that couldn't connect, it's a proprietary machine for X-Rays, and all I could do was really look at it, and do a few things, like change the IP if needed, but it's set to DHCP, and it's getting 192.168.1.X addressing, when umm, it can't be. I did ipconfig /release then /renew, nothing, still the old address, with as the DCHP and gateway. I statically set it to the 192.168.0.X settings and nothing, can't ping in or out or see the network. I set it back to DCHP reboot, and it still gets 192.168.1.X address, but there is no DHCP server serving up these address, so ummm, anyone? Oh, the X-Ray comp is plugged directly into the firewall now wich is on the 192.168.0.X network on the inside.......

Our ISP just installed a DHCP server (we won't be using it, we have static IP address for internet). Our NT box has two NIC cards, one for local network, the other connected to our cable modem. It has DHCP server running for our local workstations to get their ip addresses. But it has been shutting down with an error message stating that "The DHCP server is shutting down because another DHCP server with IP address of is active on the network." is our ISP's new DHCP server. How can I get our server to ignore the ISP's DHCP server?

A:ISP DHCP shutting down internal DHCP

You need to make sure your ISP isn't trying to renew the DHCP lease and has your IP address excluded from their DHCP servers list of non static IP's. Sounds like their error and config problem not yours. Unless you haven't excluded your static addresses from your DHCP server pool.

I visited someone's house yesterday to take a look at their computer, originally complaining that it was acting very slow.

The PC was bloated with a massive amount of AOL software. Now...they get their broad band service from SBC DSL (now AT&T, I guess). But they made it sound as if they are also paying about 20 bucks a month for AOL services as well (even though this person only uses it for e-mail. It's an elderly couple who don't really use the internet at all).

But when both are on, only one will work. It seems earthlink is set up as a dhcp server and gives an ip to that one machine. And the router will give the ip to the other.

Hi, I have a Verizon Actiontec GT704-WG modem/wireless router. I have a desktop and a sony PSP. the PSP will get online and get assigned a proper IP address. however the desktop, that is wired straight into the modem will only get a 169.254 address. I don't know why. I've assigned the desktop a static IP copying over the subnet and gateway from the sony PSP. which can get online fine wirelessly, and the desktop can ping the modem/router, as well as the PSP, but cannot connect to, or the internet. What the heck is goin on? Is the router's DHCP server not working or what? I've tried everything else, uninstalling the NIC, reinstalling. switching cables....but I figure its seeing something if its got a 169.254 address. I uninstalled the verizon software that came with it. including the firewall and stuff...went into the router( on the PSP and checked it out. seems to be ok...any ideas?? thanks guys//

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?

Yep, having some major trouble getting a directly connect cable modem to work with my WinXP machine.

Simply, Windows XP cannot contact the DHCP 'server' in my Motorola SB4200 modem. Windows XP boots, waits, then the system assigns the NIC a 169.xxx.xxx.xxx address...

I've tried this modem and connection on a Win98 machine (which I'm using right now) and it works fine. No problem with the modem...

I've also tried:

1) A different NIC

2) Resetting the TCP/IP stack via the Netsh command

3) Going over the SPECIFIC settings for the connection with a cable company rep

4) Pinging localhost - the NIC seems to be bound to TCPIP fine.

5) Firewall issues - All visable settings show off. I had ZoneAlarm on initially and stumbled on some hidden TrueVector services which I thought were the cause, but I disabled them and uninstalled ZoneAlarm - wiping all trace of it from my system. I've identified the Windows Firewall service in Windows Services and its disabled.

6) Viruses - I have NAV w/ most recent defs and have performed a full scan with no trace of viruses.

phew. I've been busy but no luck. Anything come to mind!? I know I must be missing something!!!!!!

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

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?

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

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.

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

I was created a DHCP server in Server-2008 r2 but it didn't provide IP automatically to client and on the other way in the roles sections when I click on DHCP, it didn't expand as other roles expand.
Please provide the solution.

We have a Local Area Network at work and on this network we have a VM Server with Windows 2003 Server R2 that we plan on using for Active Directory and this server also has DHCP and DNS Server configured on it. is the Server IP. NAT is not configured on the server but is configured on the router.
From this Network I have my own private address range
which connects to my NAT Router. I am able to get an ip address of from the DHCP Server for my XP Client

interface vlan10
ip address
ip nat outside
no shutdown

Next I setup a second interface on my NAT Router.
Interface Vlan 300
ip address
ip nat inside
ip helper address
no shutdown

I set up the range on the same DHCP Server
When I connect my Windows XP Client to Interface Vlan 300 I am unable to get a DHCP address on this client but on the server it says that it received an ip address.
DHCP Server address
ip address

DHCP Server Setup
Vlan 300
ip range -
DHCP Options:
003 Router
006 DNS Server
015 DNS Domain Name SQA.com
046 WINS/NBT Node Type 0x8

Any Ideas on how to fix this so I can get a DHCP address on Interface Vlan 300 I am assuming it is a configuration issue.

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.

Is it okay or dangerous to trust my wireless router?

A:Is it okay to trust the DHCP Server?

The IP address is the default for certain home broadband routers, principally various D-Link and Netgear models. This address is set by the manufacturer at the factory, but you can change it at any time using the network router's administrative console.http://compnetworking.about.com/od/routers...168_0_1_def.htmBut also see http://www.bleepingcomputer.com/forums/top...tml#entry999836

I have a vista home premium laptop I have been trying to connect to the internet using wifi. I have an xp desktop that connects quickly. My laptop says there is no response to the dhcp server. Can you help me fix this?

A:DHCP server no responce

Hi -

Let's see what your system can tell us about the wifi situation. Please download the EXE file - save to Documents. RIGHT-click on EXE file, select "Run as Administrator"


2 Notepads will open one behind the other. Save both as text files. Attach to your next post.

Also, try booting into SAFEMODE w/ Networking and try Internet connection there.

Do you have Internet Security suite installed - w/ 3rd party firewall?

Regards. . .

A:How do you contact your DHCP server?

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.
