Error occured validating the name
According to my Internet research, Power Shell 2.0 at one point before release had a built-in cmdlet called Rename-Computer, but it was removed for reasons unknown in CTP 3. Result: Return value from Rename-Computer is 1326 (Logon failure: unknown user name or bad password).
# get the credential $cred = get-credential # enter the computer in the right place Add-Computer -Domain Name EPFL -Credential $cred -OUPath "..., DC=epfl, DC=ch" # rename the computer with credential (because we are in the domain) $Computer = Get-Wmi Object Win32_Computer System $r = $Computer. Which is the time they read the computer name, so if you were to rename the computer without a restart, the network and application services would not respond to the new computer name.If you’re running newer versions of Windows like Windows 10, Windows 8, or Windows 7, then everything will work fine.It’s only with older versions of Windows like Windows XP, Windows 2000, Windows 98, etc.If nothing is grayed out, then your problem is also not with an old network adapter.If neither of these two methods worked, then you will probably just have to rename the computer.If you use the Rename-Computer cmdlet to rename the computer, but do not restart the computer to make the change effective, you can use this parameter to join the computer to a domain with its new name. PSCredential($username,$password) Rename-Computer -New Name $new Name -Local Credential admin -Force Write-Host "Please waiting for a moment to change Domain and then restart" -Foreground Color Red Add-Computer -Computer Name $old Name -Domain Name $domain -Options Join With New Name -Credential $credential -Restart I was able to accomplish both tasks with one reboot using the following method and it worked with the following Join Domain Or Work Group flags.
$old Name = Read-Host -Prompt "Enter Original Computer Name" $new Name = Read-Host -Prompt "Enter New Computer Name" $domain = Read-Host -Prompt "Enter Domain Name to be added" $user = Read-Host -Prompt "Enter Domain user name" $password = Read-Host -Prompt "Enter password for $user" -As Secure String $username = "$domain\$user" $credential = New-Object System. This was a new build and using Windows 2008 R2 Enterprise. If this value is not specified, the join is a computer to a workgroup 32 (0x20) Allows a join to a new domain, even if the computer is already joined to a domain $comp=gwmi win32_computersystem $cred=get-credential $newname="*newcomputername*" $domain="*domainname*" $OU="OU=Servers, DC=domain, DC=Domain, DC=com" $comp.
This particularly becomes important when you are first renaming the computer, and then trying to join a domain, as the kerberos handshake can not be completed without the network stack responding to the correct computer name.
Another reason is that several registry keys make use of the computer name, and those keys cannot be changed while they are loaded into memory (this is incidentally also why some programs require a reboot to complete installation or uninstallation).

Previously, I wrote an article about what would happen if you had two computers with the same IP address on the same network: an IP address conflict.
