help with Changing IP on VMguest - unable to login

[tdubb123]

Any ida how to change the IP, DG, on a VMguest, with invoke-vmguest ?

the IP got changed and now unable to login and need to change it back

Just a quick thought: What about the port group to which the VM is connected? If you are going to place the VMs into another subnet, you may also need to "plug" the VM into the appropriate portgroup (VLAN).

Invoke-VMGuest?
Do you mean Invoke-VMScript?

What Guest OS is running in that VM?

[tdubb123]

sorry yes invoke-vmscript

windows 2019

You said "unable to login", is that with a domain account?
You will need an account (domain or local) to use with Invoke-VMScript.

An alternative might be to reboot the Guest OS in Safe Mode.
But that would be a manual procedure

i have local creds but I cant sign into the console 

but I tested the local creds and see to take invoke-vmscript commands

[LucD · Accepted solution]

You could try something like this.
It assumes there is only 1 network connection defined inside the Guest OS, and that the connection is named 'Local Area Connection'

$vmName = 'MyVM'
$ip = '10.1.1.1'
$user = 'domain\user'
$pswdTxt = 'password'

$vm = Get-VM -Name $vmName

$pswd = ConvertTo-SecureString -String $pswdTxt -AsPlainText -Force
$cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList @($user, $pswd)

$code = @'
netsh interface ip set address "Local Area Connection" static $ip
'@
$sInvoke = @{
    VM = $vm
    GuestCredential = $cred
    ScriptText = $ExecutionContext.InvokeCommand.ExpandString($code)
    ScriptType = 'bat'
}
Invoke-VMScript @sInvoke
