Good morning,
I'd like to be able to automatically reset the network settings on my Windows 7 and Windows 10 PCs, but the package I'm using isn't installing correctly. The IP address is set to automatic, but the old DNS settings remain manual (even after a reboot).

Here is the setup.py file:

Code: Select all

#!/usr/bin/python
# -*- coding: utf-8 -*-
from setuphelpers import *
import wmi
import socket
uninstallkey = []

def install():
    try:
        nic_configs = wmi.WMI().Win32_NetworkAdapterConfiguration(IPEnabled=True)
        if not nic_configs:
            raise Exception
    except Exception:
        print u"No network interface found. Exiting gracefully."
        exit(1)

    for nic in nic_configs:
        print u"Please wait..."
        print u"Using DHCP on interface '" + nic.description + "'"
        nic.EnableDHCP()
        #dnsservers = ['172.16.80.13','208.67.222.222']
        #nic.SetDNSServerSearchOrder(dnsservers)
        #nic.SetDynamicDNSRegistration()
        nic.SetDynamicDNSRegistration(FullDNSRegistrationEnabled=1)
        run(u'ipconfig /renew', timeout=45)

Here are the installation logs from the console:

Code: Select all

Please wait...Using DHCP on interface 'Realtek PCIe GBE Family Controller'Traceback (most recent call last):
  File "C:\wapt\common.py", line 3846, in install_wapt
    exitstatus = setup.install()

  File "C:\wapt\setuphelpers.py", line 1046, in run
    raise TimeoutExpired(cmd,''.join(output),timeout)
TimeoutExpired: Command 'ipconfig /renew' timed out after 15 seconds with output ''\r\nConfiguration IP de Windows\r\n\r\n''
TimeoutExpired: Command 'ipconfig /renew' timed out after 15 seconds with output ''\r\nConfiguration IP de Windows\r\n\r\n''

If I delete the "ipconfig /renew" command, the package installs without error, but the DNS settings are not automatically reset.
If I replace the nic.SetDynamicDNSRegistration() command with nic.SetDNSServerSearchOrder(['172.16.80.13','172.16.80.14']), the DNS is indeed modified.
The command nic.SetDynamicDNSRegistration(FullDNSRegistrationEnabled=1) does not appear to work either.
