If you can't login to your Windows 10 machine due to "The specified domain either does not exist or could not be contacted" error, here is how to fix it.

You can easily join or leave a domain in Windows 10 from Settings app > SYSTEM > About > Join a domain. If your system is a part of domain and you can’t log in because your system doesn’t recognizes either the domain or your credentials for the domain, then this post is for you. Under such a condition, you’ll be likely to hit this error at the sign-in screen:

The specified domain either does not exist or could not be contacted.

FIX The Specified Domain Either Does Not Exist Or Could Not Be Contacted In Windows 10

Here, we have two cases. First, your machine appears to be part of connected domain but if you’ve just connected to a domain and you’re trying to log in without reboot, this error is expected to occur. Hence you should reboot and after restart, try to enter the domain credentials to log in as domain user. Second, even if your machine is part of domain, it still have local accounts that you can log in. On the logon screen, you can select either of the local accounts, sign-in to them and remove the machine from domain. If this doesn’t works out, you can always use System Restore or System Image Restore to go back to last working condition of your system.

Generally, this problem might occur, if SYSVOL folder is not shared on the Domain Controller (DC) and/or the DNS server your machine communicating with is your Internet Service Provider’s DNS server. Here is how you can fix it:
