IPCONFIG/Renew takes long time, System Event ID 1001 every 6 minutes, but connects to network

Posted on 2007-10-03

I am running Windows XP.   The system began taking an unusually long time to boot and when I do an IPCONFIG/Renew it takes 65 seconds versus 5 seconds on other computers connected to the same router.  The system event log shows Event ID 1001 about every 5-8 minutes and when I am using VPN to connect to work I lose my connection often.  I suspect the long boot time is because it hangs waiting for the network connection to get connected.

Event ID 1001 is "Your computer was not assigned an address from the network" and it says DHCP.

This began happening around the time when I upgraded my router to a Linksys Wireless-G router model WRT54G but it is unclear that the router change was a cause.  I suspected the router so I went back to my old one but I still had the problem.  I have two other XP computers which do NOT exhibit this problem.  Also, all computers are hard-wired to the router, not wireless, and I tried swapping the ports, rebooting router, cable modem, PC numerous times.  Because other computers have no problem I infer the problem is with my computer and not the router.

Once the network connects it seems to work well browsing the internet or retrieving email but my big problem is the VPN keeps getting disconnected.  I suspect the momentary times when the event log says the dchp connection cannot get an address is when the VPN gets lost.

    First step would be start simple.  Try a layer I approach.  Have you tried swapping cables?  Its possible maybe a physical connection.  Do you have a spare NIC you could try in the system, maybe one of the pins are bent having issues connection.

    That would be the first steps I would take.  After that maybe try setting a static IP address.  Does your connection drop then?

    I tried swapping the cable with no effect.  I did an IPCONFIG/Release followed by an IPCONFIG/RENEW.   It contiinues to take roughly a minute (seemed like a LONG time) for the Renew to happen.  However, the network indicator lights popped up a balloon message almost immediately saying my connection was restored and in fact it seemed to be because I could access a fresh internet page.  (My Local Area Connection is set to show Icon in lower right notification area.)  What could cause the IPCONFIG/RENEW to take so long?  I strongly suspect it is related to the very long boot time unitl the network gets established.  I suspect the boot process hangs waiting for the network so the antivirus software and other software can check for updates.

    One other data point: when I booted tonight the network Icon did NOT show up even though the box was checked to show it.  When I went to Network Connections, Local Area Connection, Properties the box was checked then all of a sudden the icon showed up.  Could this be indicative of intermittent hardware or software?

    The network hardware is built in to the computer and is not a separate card and I don't have a spare NIC around unless it is in a very old computer.

    By the way, thank you for the reply from Noodles WIU.

    If it is intermittant, my first guess would be honestly a physical issue, such as a bent pin on either the NIC, or on the port of the switch you are using.  So just as a quick test try using one of the known good cables, for the machine, and plug it into a know good port on the switch.  If the same thing happens, I would honestly guess the NIC.

    But to rule out a software issue, try using this utility.  Sometimes Winsock issues happen in the registry, and users are unable to connect to the LAN with issues such as you are describing.  This generally happens when alot of spyware got on the system for some reason, but its a simple utility, takes only a few seconds to run, just resets the defaults for winsock, and then asks you to reboot.  Heres the link.  Try that as well quick.

    Also, what happens when you reboot in safe-mode with networking?  do you still get the issue?

    winsockxpFix did the trick.  Problem is solved.

    For the benefit of others who might have a similar problem I will outline some other facts.

    1) I had already tried different cables and router ports with no impact.  Also it is not that could not get connectivity, but it was that I lost it roughly every 8 minutes and it took 65-70 seconds to do an IPCONFIG/Renew

    2) At the suggestion of someone else, I ran msconfig and turned off a large number of startup programs.  He said he had see cases of firewall software causing problems.  NoodlesWIU also suggested rebooting in safe-mode with networking.  Neither helped.

    3) Here are some messages I was getting when I did an IPCONFIG/RELEASE.  Note the strange message that it was already relased.  Not true because the network was working.


    Windows IP Configuration

    IP Address for adapter  has already been released.

    Ethernet adapter {F3EDD7CF-725E-49C1-9788-C7491F60DD69}:

    IPCONFIG/RENEW took 70 seconds and worked but gave the following error:


    Windows IP Configuration

    An error occurred while renewing interface  : unable to contact your DHCP server
    . Request has timed out.

    Ethernet adapter {F3EDD7CF-725E-49C1-9788-C7491F60DD69}:
    It then listed the reconnected connection and things worked fine.

    4) I then ran winsockxpFix.  I got errors when I tried to have it back up the registry.   A search indicated others had that problem too so I did a system restore checkpoint and then ran winsockxpFix.  After rebooting it seemed much better but my VPN no longer worked due to a "driver failure".  I uninstalled the VPN and reinstalled it and everything worked great.

    System boots faster, I don't get a line through my anti-virus icon at boot up,  IPCONFIG/RENEW takes 5 seconds, not 70.  Also my system event log no longer has the dhcp error event ID 1001 message.  I let it run for several hours while I watched the Red Sox in the world series (I'm in Boston).

    So many thanks to NoodlesWIU for the help!
