DHCP Client Tries To Aquire An IP For Not Connected Network Cards?
Oct 25, 2011
I have a problem with a Windows 7 64 bits. After power on, the DHCP client tries to acquire an IP for all the network cards, even those that are not connected.I can see in the event logs that after 2 minutes from the startup, I get one message for each interfaceQuote: >Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0xMAC_ADDRESS. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server." I have an Astaro VPN client that manifests itself as a network card and when I start it up (manually) it fails to receive an IP from the DHCP server. I believe it is related with this general DHCP problem because if I start it up within two minutes from power on (before I get the message in the event log), then it works.
Last week I hit an issue whereby I was unable to access the Internet wirelessly even though my laptop could see the router and had a good signal. I tried connecting up via an ethernet cable to no avail.
The issue seems to have started right after a Windows Update but I can't be 100% certain. If I do ipconfig /all I can see that DHCP is not enabled. I know the router is fine because my vista laptop can access wirelessly via the router fine. I tried doing some things I seen in the forum such as ipconfig /renew etc. but it said it couldn't contact the RPC server. I followed this up and was recommended to check the DHCP client service was started. It isn't even there. I was wondering if the update could have removed it.
Someone else who had reported the same issue on this forum was asked to do a system restore. I did this and the service is still not there. I am assuming that the non-existence of the DHCP client is the cause of my issues accessing the Internet.
I was looking over the menus in my router (SBG6580) config page. As of right now I have my netbook and iPhone connected. I found a laptop listed that I do not have:
00:24:2b:bb:6d:d3192.168.000.004255.255.255.000D:00 H:01 M:00 S:00Fri Dec 13 20:45:53 1901 laptop
I selected it and deleted it. Where did it come from. Should I change my router/wireless password?
Probably this error is pretty much a non-issue and I haven't a clue if the affected W7P machine, even runs Windows Server 2008 R2 (or any windows server for that matter).Is this 'server' thing, software that is by default installed (and I'm guessing it's only used when the machine networks with another machine, home/work groups)?As for if and what version the W7P machine even 'runs', the only loosely provided instructions I've found (by clicking the event log's link to information about the error), results in a webpage... Event ID 1001 ..which sort of implies to me that the W7P machine might be running 'Windows Server 2008 R2', if only because the event log error report's link led me to that web page's article, ie; the article says it applies to Windows Server 2008 R2.I tried following the article's mentions of checking to see what version of 'server' that is installed, but step 2 seems too poorly written for me to follow what's actually be said...Determine if there is a network connectivity problem To determine if there is a network connectivity problem between the‚ DHCP‚ server and domain controller: At the DHCP server, click Start, click Run, type cmd, and then click OK. At the command prompt, type ping server_FQDN, where server_FQDN is the fully qualified domain name (FQDN) of the domain controller (for example, server1.contoso.com), and then press ENTER. What's unclear to me is where it alludes to..."..where server_FQDN is the fully qualified domain name (FQDN) of the domain controller"...I see the article provides an example, but the example seems as obscure as it's parent reference.How does a user determine the "fully qualified domain name (FQDN) of the domain controller"?If that obscurity isn't bad enough, the article then lists a second step "1" stating..."At the command prompt, type ping IP_address, where IP_address is the IP address of the domain controller, and then press ENTER."..and again I haven't a clue as to what's being said, ie; we're not born with a 'domain controller's IP address' tattooed on our forehead, so how's that detail determined?Further down in the article, it lists a step 4 stating..."Type ping IP_address, where IP_address is the IP address assigned to the computer. If you can ping the localhost address but not the local address, there may be an issue with the routing table or with the network adapter driver. " ..and step 5 states..."Type ping DNS_server, where DNS_server is the IP address assigned to the DNS server. If there is more than one DNS server on your network, you should ping each one. If you cannot ping the DNS servers, this indicates a potential problem with the DNS servers, or with the network between the computer and the DNS servers."..and as the article doesn't detail how to determine the machine's 'IP Address' and doesn't detail how to determine 'P address assigned to the DNS server', again I'm left reading an otherwise virtually useless article.
I'm using windows7 enterprise edition on my Laptop. Accidentally I have removed most of the files inside ProgramData folder.
Now issue is that, DHCP Client Service is not working.
(1) Does DHCP Client really Depends upon any file there?
(2) I have seen that some of the folder have been created inside ProgramData. Can I copy any folder/file from other Laptop (Win7 EE) to my laptop to make this work?
On July 12th 2012, my computer installed updates. After rebooting and waiting for me on the login screen, I gave it a hard shutdown to check on the BIOS settings (for a little side project, in the end I did not save any changes). After booting and logging in again, I find that many services are not running. I ran a very thorough check for malware and viruses (took over 24 hours to complete), and still no solutions. I have uninstalled/reinstalled my Broadcom 802.11g Wireless Driver several times.
I now look in the Event Viewer and find that the DHCP Client service is not running! It is set to automatic start in Services.msc, but when I try to manually start it, it gives me error 1075 (some dependencies do not exist or are marked for deletion). Running ipconfig, I notice that my system is using an APIPA-formatted address (169.254.x.x), indicating that the computer couldn't find a DHCP server.
My Event Viewer is peppered with: Event 7003, Service Control Manager The DHCP Client service depends the following service: Afd. This service might not be installed. Event 7001, Service Control Manager The WinHTTP Web Proxy Auto-Discovery Service service depends on the DHCP CLient service which failed to start because of the following error: The dependcy service does not exist or has been marekd for deletion.
And that keeps repeating many times in a minute (about 30-40 cycles of it).
So I recently installed Windows 7 x64, and suddenly my wireless connection is no longer working. It worked fine with the previous Vista 64-bit OS. I'm able to connect to a different router, and the internet works fine. However, I cannot connect to my Home router. Other laptops are able to connect to it just fine (running the Windows 7 OS).
I updated the network adapter drivers, reset the router and modem, don't have the Bonjour service at all, updated everything Microsoft had for me, and tried that spoofing Network Address solution. When I try to ipconfig /renew, it freezes and eventually says "DHCP could not be reached" or something along those lines.
After all this it still doesn't work, and I still get the "169" IP address when I ipconfig.
The router is Linksys WRT54GS. My wireless network adapter is Atheros AR9281.
I just noticed this that when you open the network from the desktop it says its not connected but when you click on the network icon in the taskbar it says its connected is anyone else having this problem.
My problem is windows 7 hangs and freeze when access 2003 server Enterprise edition. This is not a small network, one of the biggest network.i have doubt on individual users on domain. before 2 months we had department wise users mean, for example Accounts@domainname.local. But after we created the individual users like john@domainname.local to all users. this is i believe the cause of problem. When we acess the server via the software it freezed for 5 seconds and then repeat to normal state. And after some time it hangs for 2 minutes.
I just finished a clean install of Windows 7 RC from Windows 7 7000 Beta. I have two network cards (not wireless) on two different routers. On XP PRO and Windows 7 Beta I was able to set up one connection as Home with Local and Internet and the other as Home or Work but without the Gateway configured to insure the first card is used for the Internet while the other is just access to the other network for gaming and file access.
I use static IP addresses so I can use DYNDNS service to get access remotely. Windows 7 RC has one network set to Home but as soon as I remove the gateway on the 2nd network (I want local access only) it goes to Public/Unidentified and won't allow any changes.
This then keeps me from accessing the other computers on the second home network. I've tried Bridging but I couldn't figure out how to create a static IP on the bridge to allow remote access. Plus it seemed others couldn't access my computer. It worked as described on the Beta but I noticed the Local and Local and Internet doesn't even show up.
If someone has a better idea to try I'd be grateful. I need two networks because my three teenagers eat up a lot of bandwidth. So I have two cards and two routers, one is on a 192.168.1.1 ip and the other 192.168.0.1.
Is there a way to force Windows 7 to make a connection a default like wireless? It seems to default to the internet connection my teenage are using no matter what I do.
Has anyone ever tried to change from XP to Vista, and create a new network connection to an FTP client? the "My Network" menu option has disapeared in both Vista and Win 7. The most logical choice therefore would be to look under Network for a menu option to do this. Nope.... Not there either.
I found out how to do it. It may be easy, but not if you cannot find it. Users should not have to search that hard to find an answer.
To help users, is there any plan to restore a menu option to do that under Networking?
How about putting Networking back under the Start Menu?
how to create your very own Desktop FTP Client using the "Map Network Drive" in "My Computer" that will allow full access to your hosting account instead of using cPanel 11 or simular. You can also drag/drop all your files/folders straight into your "Public_HTML" folder without any issues.I can assure you this is very secure and being a web developer I use this method of access constantly, this is a known method throughout the development world and most of the developers I know use this method because of it's simplicity and ease of access making life so much easier.If you have problems creating your own desktop access leave a post here and I'll try my best to help.Desktop FTP Client
1. From the desktop, click on "Start" then right click on "My Computer".
2. Click on "Map Network Drive".
3. From the screen, click "Connect to a Web site that you can use to store your documents and pictures", and then click Next.
4. Click "Choose a custom network location", and then click Next.
5. Enter the following into the Internet or network address field:
6. Enter your FTP username and account password when prompted.
Then all you do is drag/drop your files/folders that you want to upload onto your hosting/server on My Computer or Desktop and it will upload them for you.If you have any problems don't hesitate to contact me in this thread where i will try and assist you in creating your "Desktop FTP Client". Using this method is just as secure as using your own cPanel or Plesk (Any FTP Client) security.
i have following problem. At work we have HP proliant ml350 server with windows server 2008 on it, 3x windows 7 client and 25x win xp sp2 clients. Network doesn't work, clients cant see each other, can't see server and server can't see them in network and sharing center. What could be a problem? Is ipv6 protokol on windows 7 obstructing a server or something else?
I am showing not connected (red x) to the Internet even though I am connected. This just started happening a few days ago, up until then I would show the normal connected icon. I read somewhere about deleting data from my Reg Edit, but that was too complicated for me to do. Does anyone have any other solutions to this problem?
I've recently restored my Windows 7 Home Premium 64bit OS on to a new SSD using Macrium Reflect. My hosts file has always contained entries for local websites and has always worked until now. After much hair pulling and reading of forums, the only way that I could get the DNS Client to read and process the hosts file was by adding the "NETWORK SERVICE" user permission to it. It already had "SYSTEM", "Administrators" and "Users" (my user account). This was never required before, so I'm confused as to what has happened to require it now?
I've done manual reconnection (NEVER WORKS) and Troubleshooting (hardly ever works). I've tried disabling and reenabling the wireless and restarting the computer. Nothing can seem to prevent these problems from happening. Sometimes the network won't even show up!
I can't fathom how it's possible to SOMETIMES detect the network and SOMETIMES connect to it. I've thought of purchasing a repeating (quite pricey if you ask me) or perhaps using an antenna extension cable. Not sure either would be successful in alleviating my problem.
Finally, and the most odd thing, is that when the router was in the basement, I actually got a better signal even though it was LOWER than before. Not sure if this was because it was connected directly to the phone box, but the router is back on the first floor and the problem persists daily.
My wifi at work will recognize the wireless network and says it's connected. Yet there is no internet. So I use the Ethernet cable and internet works. My wifi connects immediately on my home wifi router with no issues. I had wireless working flawlessly last week, but all this week it won't connect.
my one month old laptop (windows 7) suddenly lost touch with my home network. one minute it was fine the next it wasn't. message says it's connected with no internet access, butwhen I try to print I get nothing. I suspect it's just not connected at all.
I'm running windows 7 64 bit and I'm having a strange internet issue. This has happened to me before and I've only been able to solve by doing a system restore but I figure there has got to be a much better way to solve this problem. In the bottom right hand corner beside the clock there is a little icon that resembles a little monitor (I'm no brilliant tech person so a lot of this is going to sound stupid probably) right now it shows a little yellow triangle with an exclamation point in it. When I hover over it with my mouse it says Network Connected and then No Internet Access. This is where it gets strange. I am able to connect to pretty much any website when I open my browser. Now I like to play online games and I recently got BF3. And as some of you may know you need to go through "Origin" in order to play it. Well when I connect to the Origin "library" it tells me I'm offline and basically tells me I won't be able to play multiplayer. But as I said earlier I am able to access the internet for the most part. This issue has been happening well before I got BF3 too. So I've done everything I can possibly think of. I've emptied my cache, cookies, etc. I have also done the "IPCONFIG/ ALL" thing. Rebooted the modem and the computer. done any system updates. I have also turned my firewall off briefly and tried that. It only seems to work when I do a System Restore and I really don't want to be doing that every time I have this problem. I have troubleshooted it as well.
i'm using hp pavilion and operating windows 7 ultimate. I can connect the wi-fi, internet but it notifies me no network access. It happens even with my phone modem. Three days before i can connect but now i can't
my desktop is running windows 7 home premium 64 bit and just recently it doesnt have anymore internet access. its connected via cable to LAN. it says that i'm connect to Local Area Network but no internet access.i thought it was a faulty network card so i bought a wireless USB TP-Link. i set up everything correctly according to the steps (install the driver etc.) and it says i'm connected to my home wifi network. but when i try to access Google or Facebook or twitter or any other webpage on my internet browser (Google chrome), it says the webpage is not available.
I started getting the problem where my laptop would connect to the network but there would be no internet access. I tried many of the suggestions that I found online, like flushing the dns and resetting the tcp/ip but none of them seemed to work. The only thing that I have been able to get to work is doing a system restore to the day before it began to happen. However, the next day when i swich on my laptop again I have the same problem so I have to restore again. Obviously doing a system restore everytime i want to use my laptop isn't ideal.I can't figure out what is doing this. At first I thought it was a windows update but I disabled all updates after one of my restores and it did not make any difference. I also have mcafee installed and disabled anything within that that I thought could have been an issue. As far as I can see I have not changed or installed anything after the system restores that would cause this problem to arise each time I start up my laptop.
i have hp laptop with Windows 7 64bit and i get the access to the internet through a tp-link router 2 days ago i connected the pc to the router by wirless network it connected but no internet access i tried the LAN cable also no internet access and i don't think that the problem is from the router because i can access the internet from another device such as my iphone or any other laptop
I have little trouble with my NTB. When I connect to network (wifi/lan, with net/without net it doesn't matter) programs can't be run. I tried to reinstall all network drivers but nothing happend and problem is still hereWin7 HomePrem 64-bit SP1AMD Turion II P520 DualCore (2,29GHz)RAM 4 GB
I've got a Sony Vaio labtop I bought 10 months ago in the US. I'm in Australia now but have no international warranty. Sony tells me to send the labtop to Sony repair so they can look at it. They trouble shooted over the phone but it didn't help. Asked me to reformat the hard drive which I really don't want to do. This is the problem:
The computer works fine and I can connect and browse the internet with my wireless connection. However, as soon as I connect another computer to the wireless network (or if I'm in a hotel using wireless it also happens because other computer are connected to the same network) I get the BSOD.
The problem is that I cannot say exactly when it happens. SOmetimes it happens within 1 minute of being connected and browsing. Yet sometimes it takes 20min or maybe 45min. I don't think I survived longer than 1h though with 2 computers on the same wireless network.
I didn't notice the problem at first because I only used the one computer. So, I think the problem has always been there but I didn't notice it until I connected a 2nd computer.
To get the blue screen I don't even have to actively browse. I could just scroll down on a page and it happens without warning.
My computer has been acting up lately,I haven't made any changes to my computer or anything but it seems to just not want to connect to the inter for more than 5 min. My othe computer on the house seems to connect fine, but mine will only connect for 5 min the can't find the network for 15 min and it does this repeatedly. I tried updating the drivers but there were no updates available. I ran the troubleshooter and it couldn't find a problem, it just said to make sure I was in range of the router, which I am because my computer was working fine in the same spot about a week ago.
Ok going nuts here I have been surfin the web all day on the one computer that will access the internet and have do so many things trying to get my other to access internet.We just moved and got ATT uverse installed I have dell insprion windows 7 64 it is a mini laptop no cd rom drive. anyway it has always been wireless until now.called ATT and they crashed my whole house system...looked on line I have flushed the roterdid a cdm thingturned this one and that off o turned the encryption over to tkip and for 2 seconds I had a connection then WHAM!stood on my head. danced naked during the midnight moon and no reformatting is not an option as I do not have the disc to do it but we did do a system restore
