ipconfig /release takes several seconds RRS feed

  • Question

  • Hi!

    We encounter the problem that on Windows 7 systems an ipconfig /release takes several seconds. The range the command takes goes from 1 second to over 20 seconds. 

    On Windows 10 this behavior does not seem to exist. Can it be fixed on Windows 7 or is it somewhere documented?

    Regards

    A. Sch.

  • Hi,

    Did all windows 7 machine encounter the problem? Have you tried to ping DHCP? 

    As I know, the command ipconfig /release is executed to force the client to immediately give up its lease by sending the server a DHCP release notification which updates the server's status information and mark the client IP address as available.

    Here are a few things that I should confirm with you:

    1. What about the command ipconfig /renew after you enter the command ipconfig /release

    2.Have you tried to ping DHCP server?

    Here are some steps you can try, you can test to run ipconfig /release after each step:

    1.run ipconfig /flushdns to clear the cache

    2.reset network adapter,run the command: netsh winsock reset

    3.perform a cleanup on all networking devices, reinstall the NIC drivers. Run the command netcfg -d
