Disable APIPA (Automatic Private IP Addressing)

APIPA (Automatic Private IP Addressing) – Mechanism in a small network that clients will automatically allocated themselves an IP address in the range of 169.254.x.x if no DHCP server can be contacted.

 

It may be desirable to disable this and to do this perform the following:

 
  1. Start the registry editor (Regedit.exe)
  2. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces
  3. Select the required interface
  4. From the Edit menu select New – DWORD value
  5. Enter a name of IPAutoconfigurationEnabled and press Enter
  6. Double click the new value and set to 0. Click OK
  7. Close the registry editor

 

If you have multiple adapters and wish to disable for all just create and set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\IPAutoconfigurationEnabled to 0.

System file check to look for corrupt files.

Right click at Start button > click Command Prompt (Admin) > at the flashing prompt, copy/paste this…….
sfc /scannow

> press Enter.
It will take quite sometime.
When finished, it will give you one of the 3 reports……………(paraphrasing)
1. No integrity violation.
2. Found corrupt files and repair successful.
3. Found corrupt files but unable to repair.

If the report is #1, your solution lies elsewhere.
If the report is #2, check if your problems have been resolved.
If the report is #3, use this method…………….
In the same Command Prompt (Admin) windows, copy and paste this command………..

dism /online /cleanup-image /restorehealth

> press Enter.
Again it will take some time.

Why don’t I have the option to “continue to website (not reccomended)” when I encounter a website with a certificate error IE?

If you are launching from a pinned site or desktop shortcut you don't get the option to continue.  

Around that by creating a shortcut to IE on the desktop with 'run as administrator' privileges and passing the website in the command line. 

Like "C:\Program Files\Internet Explorer\iexplore.exe" https:\\192.168.0.1
