one computer on network can't get to DHCP server

Q: one computer on network can't get to DHCP server

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.

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

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,

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.

here is what happen, I am using internet and tv from the service provider, so they send me a new router which handle internet traffic and TV traffic, but since it already doing so much the technician told me not to enable the wireless function, else it might crash often.

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.

and computers behind router B has no access to internet, but is able to log into the router B setup page.

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

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 set up a VNC for my father in his office. He has a Netopia Cayman 3546 series modem with a router built in. Currently, DHCP is enabled. The problem is that the IP changes every couple of days which means the pinhole in the router also has to be changed. Is there a way to set one IP address for the VNC computer but still have DHCP enabled for the rest on the network? If not, what would be the best way to go about this. Thanks.

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.

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.

I am setting up a linux box for a server on my home network which is DHCP, I don't want to change the entire network, I just need this server to have a static IP (so that I can get port forwarding to work). I don't even know if this is possible, if I were to give the server a static IP can my router deal with it, even though everything else is DHCP? My router is a linksys WRT54GS if that helps any.
An answer to this would be much appreciated. ^_^ Thanks
 

A:Solved: Is it possible to have one computer with Static IP on a DHCP Network?

Yes just make sure it sits outside of your DHCP scope so if DHCP starts at 192.168.1.100 and has 100 seats then make the machine be 192.168.1.99 or lower or 192.168.1.200 and higher and it would be fine. Make sure to copy all other items from what DHCP would give you. E.G. DNS, Subnet mask and gateway.

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.

A:DHCP Server (Do I need one?)

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?

I have an XP PC and a 2000 Pro PC connected to a Speedstream DSL Router that pushes out IP's and I am on the internet on both PC's.
I also have a 2000 Domain Controller server that is pushing out IP's.
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.

Thanks

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.

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?

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.

Thanks for the help.

the DHCP server is probably the correct way that i have to approach the previous networking ip address dorm question. It is perplexing, in that other students also have gotten the same type of ip address conflict. I take it that that would more than likely indicate that DHCP is in effect. What to do from here? Kindly advise further

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.

A:Is it okay to trust the DHCP Server?

The IP address 192.168.0.1 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

My internet browsing has slowed to a crawl and I cannot access web meetings and other sites I have subscribed to. I did some system testing and everything came back normal except for the following: VIA Compatible Fast Ethernet Adapter: failed DHCP Server = 10.230.40.14: failed pinging 10.230.40.14 w/32 bytes of data request timed out (this is repeated 4 times) ping statistics for 10.230.40.14 packets: send=4 received=o How can I fix this failure? Is this DHCP server from the browser; from my internet provider? Who issues this protocol number and can I change it, do I need to change it? When my computer is running the way it should it is fast and the problem with it acting so slow was intermittent for a while, now it is constant.

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?

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.
