    Guest windows local administrator password

    sambemyfriend Novice

      Hello PowerCLI Gurus,

       

      Again I came up with a question

       

      we are creating internal web portal in our organization to create VMs, we are using powercli with asp.net to work. and we are using very simple powercli command to accomplish this New-VM. I have one question, is there any way that we can change local administrator password of guest windows os on the fly?

       

      will wait for reply.

       

      Thanks in advance

          Are you using an OSCustomizationSpec when deploying the new VM ?

          In there you can change the local administrator password.

            hi LucD,

             

            We are not using OsCustomization, and we want to set different password for each vm created. can you please guide me how can we achieve this using OsCustomization?

             

            Thanks in advance

              You can use a OSCustomizationSpec as the master, make a copy (non-persisent) for each VM you are deploying (with the New-OSCustomizationSpec cmdlet and the -OSCustomizationSpec parameter) .

              Then change the administrator password in there (with the Set-OSCustomizationSpec cmdlet).

              And use this updated OSCustomizationSPec to deploy the new VM.

                Hi LucD,

                 

                Thanks for the response.

                 

                I tried to accomplish as you mentioned but no luck, I found one script and it's perfect but I don't know where to put -AdminPassword. Following is the script

                 

                $specName = "tempSpec" + (Get-Random)

                 

                Get-OSCustomizationSpec -Name $spec | New-OSCustomizationSpec -Name $specName -Type NonPersistent

                 

                Get-OSCustomizationSpec -Name $specName | Get-OSCustomizationNicMapping | Set-OSCustomizationNicMapping -IpMode UseStaticIP -IpAddress $ip -SubnetMask $netmask -DefaultGateway $gateway -Dns $DNSA

                 

                $tempSpec = Get-OSCustomizationSpec -Name $specName

                 

                $vmhost = (Get-Cluster | Get-VMHost | Sort-Object -Property MemoryUsageGB | Select-Object -First 1)

                 

                New-VM -Name $name -template $template -OsCustomizationSpec $tempSpec -VMHost $vmhost -Confirm:$true

                 

                Remove-OSCustomizationSpec -Confirm:$false -customizationSpec (Get-OSCustomizationSpec -name $specName)

                 

                will wait for the reponse

                 

                Thanks

                  You can do that like this

                   

                  Get-OSCustomizationSpec -Name $spec  | New-OSCustomizationSpec -Name $specName  -Type NonPersistent

                  Get-OSCustomizationSpec -Name $specName  | Set-OSCustomizationSpec -AdminPassword xyz

                    hi LucD,

                     

                    I used the following script and it ran successfully but VM was not customized, it came as it was create as template, nothing has been changed not even IP

                     

                    $vmname = "Test2008-1"

                    $vmtemplate = "Windows2008R2S"

                    $vmhost = "vmhost02.test.local"

                    $VLAN="25"

                    $ip = "10.101.35.50"

                    $subnetmask = "255.255.255.0"

                    $gateway = "10.101.35.1"

                    $dns = "10.101.35.5"

                    $DomainPass="somepass"

                    $DomainAccount="domain\someuser"

                    $Domain="domain"

                    $vmfolder = "MyFolder"

                    $datastore = "MyDS"

                    $cluster="MyClu"

                    $TimeZone = "035"

                    $Password = "Passw0rd"

                    $OrgName = "TestOrg"

                    $FullName = "fullname"

                    $ProdCode = "xxxx-xxxx-xxxx-xxxx-xxxx"

                    $oscustspec=$vmname+"-cust"

                     

                    new-oscustomizationspec -name $oscustspec -ostype Windows -fullname $FullName -OrgName $OrgName -namingscheme Fixed -NamingPrefix $vmname -ProductKey $prodcode -LicenseMode Perseat -adminpassword $password -domain $domain -domainusername $DomainAccount -domainpassword $DomainPass -ChangeSid

                     

                    Get-OSCustomizationNicMapping -Spec $oscustspec | set-oscustomizationnicmapping -ipmode UseStaticIP -IPAddress $ip -subnetmask $subnetmask -defaultgateway $gateway -dns $dns

                     

                    New-VM -Name $vmname -Template $vmtemplate -VMHost $vmhost -datastore (get-datastore -name $datastore -vmhost $vmhost) -OSCustomizationSpec (Get-OSCustomizationSpec -name $oscustspec)

                     

                    I don't know where I messed up the script.

                     

                    waiting for your reply.

                     

                    Thanks in advance.

                      Any clue in the customisation (see folder C:\Windows\Temp/vmware-imc) and/or sysprep logs (see KB2001932) ?

                        Hi LucD,

                         

                        I have again tested the same script with windows 2012, it changed password but it needs manual intervention. like first I've to insert old password then it restart and then it ask for Language, keyboard selection and then it asked to click accept on license agreement.

                          That error about the /shudown option is strange, that explains probably why the OSCustomizationSpec didn't get applied.

                          And since the sysprep didn't start, you get the prompt for the setup.

                           

                          Now why this /shudown is in there is not clear to me.

                          Which vSphere versions are you running this against ?

                              LucD,

                               

                              I need your expert opinion, is it reliable to use oscustomization tool to auto provision vms using our custom asp.net based application.

                               

                              will wait for your reply.

                                I know this is old, but try using a non-sysprepped image. My customizations weren't working but now that i created a template without running sysprep, it works.
