"Your computer could not renew its address from the network (from the DHCP server) for the network card"?

I saw this question posted several times here, but I can't find someone who has exactly the same problem I have.

This problem started a week ago. Basically, my computer loses its connection ethernet once per hour to around the same exact time. which is only for about 5 seconds, but it's enough to get Skype and other things while I'm working, and it's very frustrating because I use Skype to talk with customers, and it looks unprofessional when my calls fall every single time. my computer can also use wireless (which does not go down), but he's too unstable for my work.

now on the error message I posted. I get this error in my observer of events in about 30 minutes until my ethernet goes down, so I don't know if they are interlaced or not, because I don't get any errors when my ethernet really crashes.

Here's what I've tried so far without success:

-temporarily disable the firewall and antivirus

-updated driver for both my wired network cards and wireless (both were UTD)

I don't know what to do because I've never had this problem before.

Here is some information on my computer if that helps all:

OS: windows 7 Home premium (x 64-bit)

computer model: gateway DX4870

Look on the side of the router and make sure that the DHCP lease time has not set to 60 minutes.  As a simple solution you can just assign a reserved DHCP or a static address to the computer (in the router).

PS: You'll find the DHCP lease on the map with the command ipconfig/all command at a command prompt

  • Satellite U500 start problem - "your computer could not be started."

    I bought a Toshiba U500 Satellite 2 months ago and whenever I turn it on the message 'your computer failed to start' and startup repair must check my system for problems.

    After that it checks my system (which takes a lot of time) it says that it cannot solve the problem and I can choose "Finish" and the computer shuts down. When I start the computer again I have the option "Start windows normally" and when I choose what it starts. The whole process is very long, that take a long time to start the computer (I have Vista).

    I was not able to understand what the problem is and I would really appreciate any help as much as the laptop is brand new. Thank you!

    In my opinion, you should backup all important data and install again. your laptop's HARD drive image and after 25 minutes only you will own operating system preinstalled and everything will be OK again.

  • Virtual machines do not get IP address from the DHCP server

    Hello! I just spend Xenserver to ESXi. Created a couple of virtual machines and none of them gets an IP address from our DHCP server (DHCP server is a physical PC), and instead, they get a number of internal 192.168.x.y allowing connection to the internet.

    Looks like a way to do this is to install a virtual machine that is a router, as M0n0wall, and route traffic to connect to the external network and finally to access internet. But this is not what I have to do.

    I need to have virtual machines that are server to get an IP reserved for our DHCP server, and then our local windows client should be able to access it directly.

    I searched on google and forums for this but I can't seem to find how to configure virtual machines to directly belong to our local network.

    I thought that VMware would have a simpler way to do so than XenServer, but I was stuck on this one day now and really frustrated as I get not before with this project, stuck on this little problem... sigh...

    Thanks for your help.

    GER.

    ESXi does not IP addresses to the virtual machines it host - if the virtual machines are not able to access your physical network than that of the thw two virtual machines acts as a DHCP server - now to the question of network - if you are not able to reach the virtual machines on the physical network or achieve fitness network virtual machines , then there is a problem with the physical connection to the ESXi host, possibly the configuration of the physical port that connects to the - is a way to test this theory to assign an IP address on the same network that the management port - if you are able to access the virtual machine, then you know that the problem is with the switch port.

  • That means "another device on the network use the IP address of your computer"?, that means "another device on the network is using the IP address of your computer?

    That means "another device on the network use the IP address of your computer"?, that means "another device on the network is using the IP address of your computer?

    A

    Most likely, the computer becomes a network address of a router. The assignment of an address ("lease") expires and must be renewed after a certain period of time, which could be an hour or a day. The lease expired without being renewed because the device has been disconnected at the time. Meanwhile, the address has been leased to another device on the network, or maybe the router has not updated its list of addresses the leases. When the device offline comes back online, a conflict results. Depending on the type of router you have, the conflict can resolve itself automatically. If not, then in the menu bar, select please

    ▹ System Preferences network ▹ 

    If the preferences window is locked, click the lock icon in the lower left corner and enter your password to unlock it. Click the Advanced button, and then select the TCP/IP tab in the sheet that drops down. Look at the menu option

    Configure IPv4

    If the selection in this menu is

    Using DHCP

    Click on the button

    Renew the DHCP lease

    Test.

    Make sure that you have more than one DHCP server on the network. That could happen if you have more than one access point Wi - Fi, or if you have a router and broadband a wide device distinct in connection mode sharing.

    B

    Less likely, you have a network address that you assigned yourself and another device is itself by assigning the same address. In this case, the selection to configure IPv4 menu will be either manually or using DHCP with manual address. This kind of conflict will not be resolved automatically. You have the following options to solve:

    1. Change the selection in menu using DHCP.
    2. Change the address assigned manually to one that is not used by another device.
    3. Change the address of the other device.

    Which of these options you choose depends on the details of why you use a static IP address. Any changes you make to the network settings is necessary before taking effect. To do this, click OK, and then click apply.

    If the router is also your device at wide band, then he may be operating in bridged mode. In this case, only one customer at a time will be able to connect to the Internet. Consult the manufacturer or ISP documentation for how to reconfigure the device in the connection mode sharing.

    C

    According to a report a "DirectTV" receiver can cause the problem. If necessary, disconnect the device from the network, or power off and test. Consult the support services provider.
