Windows 7 DNS Issue
Hello Experts,
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.
Thanks,

Tried the IP with a static address, proxy server is off and ipconfig shows correct information. nslookup does not resolve the FQDN of the DC.
Checked the registry and the NameServer entry was correct. NSLookup:
Default Server: Unknown
Address: 10.2.0.1
IPv6 is turned off.

How did you fix the trust issue, unjoin/rejoin?
I assume that you are using the same machine name when it was windows 7. Go in to your DNS and remove any entries of that machine name in forward and reverse lookups. Then an ipconfig /flush dns on both the server and the workstation in question

apologies for the delay, to resolve the Domain Trust issue, i logged in using the local administrator, unjoined the domain, rebooted, changed machine name, rebooted and joined the domain again.
I will attempt the DNS entry modification in the morning.

No change, another 'symptom' is that i can locally but not outside of the network to any public addresses.

If local DNS also fails and the correct DNS server shows in ipconfig try turning off ipv6 if it is not being used on the network. If the correct server does not show and you have tried statically assigning already try resetting the name server in the registry.
