This issue is inline with my thread
here. And though it has subsided a bit, I am still getting calls about the issue here in the US. I have had some that no matter what I did, the only solution was to do a complete N&P. For me, 98% of the problem was that a pushed down update for 3rd party drivers was not only breaking DHCP (No valid IP) but was also completely removing the LAN drivers but not affecting anything Wi-Fi related.
What I have done for recently installed Windows 10 machines (and ones that I could fix) as well as currently servicing machines not affected yet was to turn off the ability to download manufacturers apps. That has helped a lot.
Do that by the following:
- Right click Start (Windows icon)
- Click System
- Click Advanced system settings (left side)
- Click Hardware tab
- Click Device Installation Settings
- Check No
- Save, exit and reboot.
The above seems to work fine and have not been able to recreate the issue afterwards. Granted its not a cure-all solution. Many times just running SDI to reinstall the LAN drivers has worked. A point to note is that nearly every instance I have had the customer has had the Windows 10 Anniversary edition installed. Only one issue have I had with the 1607 build.
You can also (on affected machines) use the following through command prompt (run as admin) or make it a .bat file.
- netsh int ipv4 reset reset.log
- netsh int ipv6 reset reset.log
- ipconfig /flushdns
- nbtstat -R
- nbtstat -RR
- netsh int reset resetlog.txt
- netsh int ip reset
- netsh winsock reset
And here is the .bat file you can make. Copy & Paste into a .txt file and save with the extension: .bat
@echo off
echo Quick fix for broken DCHP!
echo WARNING: My or may not work. Use at your descretion!
pause
netsh int ipv4 reset reset.log
netsh int ipv6 reset reset.log
ipconfig /flushdns
nbtstat -R
nbtstat -RR
netsh int reset resetlog.txt
netsh int ip reset
netsh winsock reset
echo Type EXIT then reboot the machine!
I hope this can help someone.
