I'v been trying to add a computer to my domain add-computer -DomainName Gary.psv
but this error pops up "The specified domain either does not exist or could not be contacted"
I'm confused Am I suppose to match DNS between both servers? I'm using powershell btw.

When trying to query AD from new windows 2019 Server with different domain, it is throwing below error
"get-aduser : A call to SSPI failed, see inner exception"
Same query from same user is working fine from Windows 2012R2 server.
Workaround applied
Working if trying from specific Domain Controller.
Issue: we need to hardcode domain controller rather than directory name
When trying with "-credential (get-credential /username)" (with same user)it is working fine
Issue: It is prompting for credential page
Kindly suggest how we can resolve this error without changing the AD query so as to automate the process.
From the screenshot it looks like the server you're addressing is something.com? Eg you're trying to query the entire domain rather than a specific server. Annoyingly that doesn't work as it expects a specific server. The work around I found is to add something like this at the beginning of the script.
$dcServer = get-addomaincontroller -discover -domain mydomain.com -forcediscover | Select-Object -expandproperty hostname
which can query the domain as a whole and find the DCs with it, and pick one at random. Also has the benefit that is the individual DCs change in the future the script continues to work.
After which you can run your query (and any others within the script) with the parameter listed as :
-server $dcServer
In my case CreedSSP was disabled.
PS console:
Enable-WSManCredSSP -Role Server
I have used windows 2008 AD since 2013.and I have secondary domain as well. unfortunate due to hardware failure the primary domain was corrupted. I configured a new AD on windows 2012R2.now my concern is when I restart my primary domain it giving many errors. "Naming information cannot be located because: The specified domain either does not exist or could not be contacted. Contact your system administrator to verify that your domain is properly configured and is currently online."
It will automatically resolving when I switch on the secondary domain.
Now what I want to do , I need to resolve this error..

Hi this is a known issue.
These issues may occur if TCP/IP filtering is configured to permit only port 80 for TCP/IP traffic.
And you can consult the link for a possible solution
When attempting to connect to domain controller in Windows Server 2019 the following error comes up "The join operation was not successful. This could be because existing computer account having name was previously created using different set of credentials."
I have attempted renaming the computer and connecting and also tried deleting it from the domain controller to be able to add it back but both did not resolve the issue. Any suggestions workarounds are appreciated.
When entering your credentials, enter them as follows:
domain\adminaccount.
and of course, you will replaced "domain" with your domain name
and then \ and then your admin account
Check if computer account already exists on the domain.
If it already exists, delete it and try to join machine to the domain.
If it doesn’t exist. Create it, than remove (do this on the domain server) and then try to join the domain again (from the client machine).
I am wondering if it's possible to use the 'net user' command in Windows to pull up details on a user in a different domain? The domain is connected to us. For example, I can log in as that user in the other domain from the same network.
This is the net user command I use to pull my local details:
net user myusername /domain
Is there a way to specify a different domain name? Or are there other commands that will do something similar? I'm am wanting to use a command to verify the password expiration date on the other domain.
No, you cannot use it that way. The /domain flag is used just for specifying that the command should be run on the primary domain controller for the domain that you are in. Otherwise, the command runs on the computer (server) where you are running the command.
https://support.microsoft.com/en-us/help/251394/how-to-use-the-net-user-command
You can, however, use PowerShell cmdlets to manage users in Active Directory. The following documentation is for the Get-AdUser cmdlet.
https://technet.microsoft.com/en-us/library/ee617241.aspx
You probably want to pass in the Identity flag and specify the full Distinguished Name for the user object. For example: -Identity "CN=SaraDavis,CN=Europe,CN=Users,DC=corp,DC=contoso,DC=com"
Try to issue following command in powershell
Get-ADUser "username" -Server "domaincontroller.localdomain"
You can log onto a virtual machine or windows server on that domain and run the same command to get that domain user's details.
Powershell like in Matson's answer is probably the better option if you rarely have machines open on that domain, but if you are already working on a machine in that domain your command works just fine.
When you restore VM (that belongs to a windows domain) from (an old enough) snapshot you'll get this error:
trust relationship between this machine and domain failed
This happens because domain controller periodically renews computer account password (and maybe few other things).
Is there any way to configure domain controller (or anything else) in such way that this doesn't happen? I don't care about security risks/etc -- all this is in controlled environment.
Two solutions:
You can try the policy like #Harry mentioned to disable machine password: Reference: Domain member: Disable machine account password changes
Per the article: The Domain member: Disable machine account password changes policy setting determines whether a domain member periodically changes its computer account password. Setting its value to Enabled prevents the domain member from changing the computer account password. While not recommended for production environments, setting the value to Enabled his is what you would set the value at in your controlled environment which would eliminate the identified problem.
Another way to handle it is using PowerShell. This won't prevent it from happening but will solve it, you can put it in a script and use:
Test-ComputerSecureChannel –Server dc -Repair Reference: Test-ComputerSecureChannel
For those of us using a production domain controller, it's easier to do this on the VMs.
Set this in the registry to disable automatic machine account password changes:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Netlogon\Parameters]
"DisablePasswordChange"=dword:00000001
If you ever get "The trust relationship between this workstation and the primary domain failed", one easy fix is to log in as local admin (or a domain account with network disconnected) and use the powershell Reset-ComputerMachinePassword cmdlet as follows:
$credential = Get-Credential
# Enter domain admin account when prompted
Reset-ComputerMachinePassword -Server ClosestDomainControllerNameHere -Credential $credential
