Recently, while trying to add a Windows 10 computer in a domain (Windows Server 2016 domain) I encountered “The specified domain either does not exist or could not be contacted” issue:

The specified domain either does not exist_specified

Desktop Experience

The specified domain either does not exist_specified_02

PowerShell

I researched the issue on the Internet and learned that this is quite an issue with Windows 10 computers (both Windows 10 Pro and Windows 10 Enterprise). However, I managed to solve it in the following format.

Added the preferred DNS server:

The specified domain either does not exist_AD_03

Added the DNS suffix for this connection, and checked the Use this connection’s DNS suffix in DNS registration:

The specified domain either does not exist_AD_04

Immediately, the network connection from unidentified network turned into identified network by recognizing the domain WS2016SC.local:

The specified domain either does not exist_AD_05

Afterwards, I have joined a computer in a domain successfully:

The specified domain either does not exist_AD_06

Hope you’ll find this post informative.
