I've seen a few people posting about this now across other forums but no solutions as far as I can see.

I work for an ISP and we have had a surge in customers with invalid IP configuration faults in the past two days, today being 08/12 12:46 in our time zone. This seems to be happening regardless of location (we are a nationwide business based in New Zealand), it is also not dependent on what modem/routers they have nor their service type.

Some of the things that we have noted are:

169.254.x.x IP address by default

Windows troubleshooter gives the error "invalid IP configuration" and cannot resolve it

Sometimes rebooting fixes it but no more than half the time

Release/renew through command prompt also works some of the time

Having to set static IP/DNS in the offending computer (which is only a temp fix really)

Does happen across all computers that the customer has

Most of our customers are not affected

If anyone could help, that would be greatly appreciated. Even if we knew what the cause was (windows updates etc) then we could let the customers know.

Thank you in advance.

** UPDATE **

Just to let everyone know, we have had response from Microsoft's Global Escalations team advising that it is being investigated currently but no solid answers/ideas as of yet as to what it could be.
