Rename computer and join to domain in one step with PowerShell

Question

Goal  On a computer running Windows Server 2008 R2  use PowerShell 2 0 to    Rename the computer Join the computer to a domain   Condition  Steps 1 and 2 must be performed together  i e   without a computer restart between them  Functions I m Using  These are the PowerShell functions I ve created for each step   Rename Computer  According to my Internet research  PowerShell 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  My version uses WMI   function Rename-Computer       param    Parameter Mandatory  true   string  name        process               try                        computer   Get-WmiObject -Class Win32 ComputerSystem              result    computer Rename  name               switch  result ReturnValue                                       0   Write-Host  Success                    5                                        Write-Error  You need administrative rights to execute this cmdlet                       exit                                   default                                        Write-Host  Error - return value of    result ReturnValue                     exit                                                   catch                       Write-Host  Exception occurred in Rename-Computer    Error                     Join Computer to Domain  As you can see  this function is really just a wrapper for the built-in cmdlet Add-Computer that gathers the domain name and creates some credentials to use    function Join-ComputerToDomain       param    Parameter Mandatory  true   string  domain        process               try                         domainCredential    Host UI PromptForCredential  Enter domain credentials    Enter domain credentials to be used when joining computer to the domain        NetBiosUserName               Add-Computer -DomainName   domain -cred   domainCredential                   catch                       Write-Error  Exception occurred in Join-ComputerToDomain    Error                     Steps I ve Tried  Attempt 1   Call Rename-Computer Call Join-ComputerToDomain Restart   Result  Output from Rename-Computer indicates that name was changed  but after restart  name did not change  but computer was joined to domain  Attempt 2   Call Join-ComputerToDomain Call Rename-Computer Restart   Result  Return value from Rename-Computer is 1326  Logon failure  unknown user name or bad password   I assume this is because domain credentials are required for the rename once it s joined to the domain  I attempted to use credentials with the Get-WmiObject call in Rename-Computer  but it threw an error about not being able to use different credentials on the local system    Attempt 3   Call Rename-Computer Restart Call Join-ComputerToDomain Restart   Result  Everything works as expected  but extra restart required  Works but I want to eliminate the restart at step 2

Rename-Computer was removed from CTP3 because there are a lot of things done when renaming a computer and MS either didn t want to recreate that process or couldn t include all of the necessary bits   I think Jefferey Snover said to just use netdom exe instead  as that is the best practice for renaming a computer on the command-line   Not the answer you were looking for  but should point you in the right direction

As nobody answer  I try something    I think I understand why Attent one does not work  It s because joining a computer to a domain is somehow also renaming the computer  the domain name part  enter in the name of the machine    So do you try to do it in full WMI way  you ve got a method in Win32 ComputerSystem class called JoinDomainOrWorkgroup  Doing it on the same level perhaps gives you more chance to make it work

There are actually several reasons that you have to reboot after renaming a computer  or when joining a domain  which is basically the same operation with validation by AD   One being that on NT based computers  I believe this started with Windows 2000   the Application and Network services read the computer name when they are started  Which is the only 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  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    You could use the RunOnce registry key  msdn microsoft com en-us library aa376977 28v vs 85 29 aspx  to run your domain join script automatically upon reboot  but you re still going to have to reboot for both operations   If you really wanted to get tricky  you could add some code to your rename script that would set the RunOnce registry key to launch the domain join script upon reboot  Be aware though if you are going to do this  that the script that will be writing to the HKLM hive must be run as an administrator  especially important if you have UAC turned on    If you want to do that  you d use something like this at the end of your Rename-Computer function   Set-Location -Path  HKLM  SOFTWARE Microsoft Windows CurrentVersion RunOnce  Set-ItemProperty -Path   -Name joinDomain -Value  C  scripts joinDomain ps1  Restart-Computer   This will create a subkey in the RunOnce registry key  assuming you are running Vista 7 2008  named  joinDomain  with the value of  C  scripts joinDomain ps1   If that doesn t work for you  try changing the second line to this   Set-ItemProperty -Path   -Name joinDomain -Value  C  WINDOWS system32 WindowsPowerShell v1 0 powershell exe  C  scripts joinDomain ps1     Let me know if you have troubles

I was able to accomplish both tasks with one reboot using the following method and it worked with the following JoinDomainOrWorkGroup flags   This was a new build and using Windows 2008 R2 Enterprise   I verified that it does create the computer account as well in AD with the new name   1  0x1  Default  Joins a computer to a domain  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 JoinDomainOrWorkGroup  domain    cred getnetworkcredential    password   cred username   OU  33   comp rename  newname  cred getnetworkcredential    password  cred username

the Options JoinWithNewName in Add-Computer can do this work       -- JoinWithNewName  Renames the computer name in the new domain to the name specified by the NewName parameter  When you use the NewName parameter  this option is set automatically  This option is designed to be used with the Rename-Computer cmdlet  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     oldName   Read-Host -Prompt  Enter Original Computer Name   newName   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  -AsSecureString   username     domain  user    credential   New-Object System Management Automation PSCredential  username  password   Rename-Computer -NewName  newName -LocalCredential admin -Force Write-Host  Please waiting for a moment to change Domain and then restart  -ForegroundColor Red Add-Computer -ComputerName  oldName -DomainName  domain -Options JoinWithNewName -Credential  credential -Restart

I was looking for the same thing today and finally got a way to do it  I was hinted that it was possible due to the use of sconfig  which ask you if you want to change the computer name after joining it to a domain  Here is my raw code line  It might be enhanced but to tired to think about it for now    strCompName   Read-host  Name    strAdmin   read-host  Authorized user for this operation    strDomain   read-host  Name of the domain to be joined   add-computer -DomainName  strDomain -Credential  strAdmin Rename-computer -newname  strCompName -DomainCredential  strAdmin

I would like to offer the following that worked in an automated capacity for me  It shows the sequence of steps and the relationship between setting the name first  then joining the domain  I use this in a script as an orchestration point for Win2008r2 and win2012r2 via Scalr CMP for EC2 and Openstack cloud instances     userid   DOMAIN  USERNAME   secure string pwd   convertto-securestring  SECRET PASSWORD  -asplaintext -force  creds   New-Object System Management Automation PSCredential  userid  secure string pwd  Rename-Computer  newhostname  -DomainCredential  creds -Force WARNING  The changes will take effect after you restart the computer OLDHOSTNAME   Add-Computer -NewName  newhostname  -DomainName  DOMAIN -Credential  creds   -OUPath  OU MYORG OU MYSUBORG DC THEDOMAIN DC Net  -Force WARNING  The changes will take effect after you restart the computer OLDHOSTNAME   Restart-Computer   One caveat is to be careful with the credentials  pull them from a key store rather than hard-coded as illustrated here     but that s a different topic   Thanks  everyone  for your answers

I had a slightly augmented issue  I needed to rename a machine and then RE-JOIN a domain it was already a member of and could not find where to do that but its seems very close to what is here  The individual solutions above don t do it but with some togetherness    If you try to rename  you get denied  If you rename and then rejoin  you get an account already exists error  You need to bail from the domain by joining a workgroup and then you can run the rename and join in one command    Chops   Get-Credential    Or bring in a stored credential  NewComputerName    WhoImGonnaBe     or value from CSV  MyDomainName    MyDomain  Add-Computer -WorkgroupName NotADomain -force -DomainCredential  Chops Add-Computer -DomainName  MyDomainName -Computername  ENV Computername -NewName  NewComputerName -DomainCredential  Chops -Force -Restart    If running locally you really only need the -NewName and can omit the -Computername
