NAP and Sleep Mode RRS feed

  • Question

  • Dear All,

    I implemented DHCP-NAP-Enforcement in my Environment and it is working perfectly.but i have a problem is that when Compliant Computers access the network and then goes into sleep mode, when they wakeup i see that they are assigned the full mask 255.255.255.255 and I have to restart the NAP Service to obtain the Default Mask, Checked event viewer and i found this error happens during this scenario

    An error occurred when DHPQEC tried to renew DHCP lease in the adapter {9b5cb0da-2416-40b1-bcfa-1f95a8389c15}. Error code is 0x79

    DHCP server: Windows 2008r2

    Client: Windows7 SP1

    NPS Server: Windows 2008 R2

  • Hi Amr,

    Please configure the network interface on the computer to not sleep during sleep mode. This should not add much power consumption and should eliminate this problem.

    Let me know if you need more information.

    Thanks,

  • Hi,

    According to your description, I assume that the computer might lost connection when it went into sleep mode.

    Was the IP address normal after the computer woke up?

    In addition, would you please post the entire error for us? In these scenario, we can provide further assistance.

    Best regards,

    Susie

  • Dear Susie

    What do u mean the IP is normal ? if you mean if it assigned the same IP after waking from sleep mode then the answer is yes, but with mask 255.255.255.255.

    for the Errors i just have the error that i posted in the Event viewer , do u need any other logs ?

  • Susie,

    I dont have any other errors in the Event Viewer , suggest me other sections in the Event viewer or log files to trace it for you

  • Hi,

    You can check the event logs on the NAP client and server, and check the NPS accounting logs in %windir%\system32\logfiles.

    In addition, if you have enabled remote access tracing, you can also check the log files in %windir%\tracing.
