Do you have a home router?  Likely, I think.   Make sure you know the settings, do a factory reset and set it up again. Now test and see if NS Lookup works. The reset will fix DNS anomalies.

Also I can nslookup using 8.8.8.8 outside it is only internal

Have you tried restarting all computers and devices after the power failure?

Were the servers on a UPS?

John,

Yes most are on UPS but the power went on and off several times

The surge from repeated on / off cycles may have damaged some things.

On both Server 2012 machines, run DISM.

Open cmd.exe with Run as Administrator and run dism.exe /online /cleanup-image /restorehealth .  Allow to complete, then restart and test.

Some problem with server ip config, try to reset virtual nic in vm

Theses are on both physical and VMS'

JohnBusiness Consultant (Owner)Commented:
A software fix that can precede DISM is to run TCP/IP Reset, DNS Flush on all machines (physical and virtual).

Open cmd.exe with Run as Administrator
Then: netsh int ip reset c:\resetlog.txt
Then: ipconfig /flushdns
Then: restart the computers
