I have a client and the accounts manager upgraded to Windows 10, had some issues and rolled back to Windows 7. The machine had a 'Trust Relationship' issue, i resolved this but the PC can not resolve DNS. Tried the following:
- ipconfig /flush dns
- netsh int ip reset
- IP address to DHCP, from the DC,
- ping -4 www.google.com
Nothing worked. If anyone has any suggestions, i would appreciate it.
My last fix is looking like a rebuild.
