Windows update hosed the internet connection to my VMs.

Hi experts, all of a sudden my windows VMs couldn't connect to the internet. It says it's connected to "unidentified network - no internet access". I'm using VMWare Workstation for the VMs. Windows server 2012 and 2008 R2 are the guest operating systems that can't get to the internet. I've tried enabling LAN on the servers, switching from Bridged mode to NAT, enabling network discovery...

I'm attaching the results to ifconfig. I've got no default gateway and subnet mask looks weird.

I looked at my system restore points, and it looks like 7 days ago windows pushed a "critical update", and it seems to have wiped out all my previous restore points.

Thanks,
Luke

I expected a persistent route but do not see one to the gateway. What is gateway IP, add it back to config

I assume it's 192.168.0.1, from this screenshot taken from my host machine. Would you mind helping me add that back to config?

I use VMware Workstation, and fully up to date (yesterday was Patch Tuesday). All works.

On the Host, run TCP/IP Reset, DNS flush and test.

Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache
Then restart the computer

Then for the guest, go to the VMware Network Editor and Run as Administrator. Reset the NAT Network.

Restart the computer and test.

If all of this does not work, uninstall VMware Workstation. restart, and reinstall it. That will also work.

Livesaver!! Hey any idea why it wiped out my system restore points too? Any way to get those back?
JohnBusiness Consultant (Owner)Commented:
No, I do not know why that happened unless you were just far enough behind for the update to do a refresh update (install) which keeps everything but does clear out restore points. If that happened, no way to get them back.

Livesaver!!    <-- Thank you for your kind comment. I really do appreciate it.
