I’ve seen this error recently in my Hyper-V lab when trying to a join a computer to my domain controller. I knew it was something to do with DNS, but here are the things I did in order to resolve.
- Here are the commands I was running:
# First, verify Subnet / Gateway. Get-NetIPConfiguration # Looks good, let's ping domain controller. Test-NetConnection server2012 # Returns 10.13.13.250 - good # Now ping the domain Test-NetConnection testdomain.com # No replies, dang it. Oh wait! Let's set the domain controller as the primary DNS server # Change settings in Network Connections Get-NetConnectionProfile # See interfaceIndex of 4 for my LAN NIC. Get-DnsClientServerAddress -InterfaceIndex 4 -AddressFamily IPv4 # See that I'm pointing to my gateway as the primary DNS server - wrong! Set-DnsClientServerAddress -InterfaceIndex 4 -ServerAddresses ("10.13.13.250","18.104.22.168") # Ping testdomain.com again, dang it still fails! Wait, need to flush dns! Clear-DNSClientCache # Returns domain name, good to go! # Now I can try to join again and it should work! Add-Computer -Domainname "testdomain.com" -Credential (Get-Credential) -Verbose # Success!
