Problem with Dhcp-Client

Question

I'm having a problem with my internet connection.. I have had to use ipconfig to initialize my network. not a big deal. but every 20 minutes the Dhcp-Client is trying to renew my lease, and doesn't like being told "no". this event is effective in stopping all internet access for a brief moment, then it tries again, and then it goes away for 20 minutes... the only effective means to stop this process was to stop the WinHTTP Web Proxy Auto-Discovery Service. of course when I eventually rebooted.. win changed dhcp back to auto.. and http back to manual (from disabled) .. and the whole thing started logging errors again. what i would like to know is ... why is dhcp not reccognizing a good lease, and why every 20 minutes with one retry ?

Hi xpostal,

Thanks for posting to "Getting Ready for Windows 7"  community forum.

Are you running this system in a domain? is the router issuing the DHCP?  Would you provide information of what the network consists of for proper instructions towards the situation encountered?  Are you running a Windows Firewall or third party software firewall?

From just basic belief of your system as being on a home network,  and it sounds as though you may have a laptop, so probably wireless connection,  I would reset the router if it is hosting DHCP.  Or if your system is wired to a router, verify the port and or cable is working properly by moving the cable to another known good port on the router and/or using another known good cable to troubleshoot connectivity to the router. 

It's a good idea to also, verify the Network settings from StartORB/ Control Panel / Network and Internet Options / Network and Sharing Center / Change Adapter Settings / Right Click on the Network Connection and select properties. 

If your Network adapter is wireless, and you frequently visit other networks then your main home network.  The DHCP Cache may be full.

When a user takes his machine with Windows 7 OS (laptop) from one network to another network, then DHCP client first tries to get the network hint (SSID) of the new network. When this information is obtained by the network that information is maintained in DHCP cache.  If the DHCP cache is full,

Try clicking the START ORB/ In the Search line type COMMAND/Right Click on the Command Prompt and select RUN AS ADMINISTRATOR

From the command prompt type IPCONFIG /RELEASE ----hit enter - let it cycle through the process then issue the command IPCONFIG /RENEW ---hit enter.

Let us know if this assists you with this issue or if further assistance is needed involving this matter.
