That issue was resolved in the latest version, see Invoke-VMScriptPlus V3
The update adds the new Switch -NoIPinCert, and some other new features.

Give it a try.

Thank you for such a great Function!!
I had an issue when running it. I would get:
Invoke-WebRequest : Unable to connect to the remote server

After digging into the code I saw you were replacing the $ip for the $hostname on line 247 which worked great for those of us that are using custom SSL certs on the host that does not include a SAN IP address.

It turned out the failure was coming from line 330 & 331:
$fileInfo = $gFileMgr.InitiateFileTransferFromGuest($moref, $auth, $tempOutput)
$fileContent = Invoke-WebRequest -Uri $fileInfo.Url -Method Get

$fileInfo.Url contained the IP address not the hostname. I added the following one line of code and modified line 331 and all works great now!!

$Url = ($fileInfo.Url).replace($ip, $hostName)
$fileContent = Invoke-WebRequest -Uri $Url -Method Get -Verbose

Running on Win2016, PowerShell version 5.1.14393.3471, VMware PowerCLI 11.5.0 build 14912921

The Resolve-DnsName cmdlet missing issue can be fixed by replacing that with

$hostName = [System.Net.Dns]::GetHostEntry($ip) | Select-Object -expandProperty HostName

Note that the cmdlet occurs twice in the function.

But in PS v7rc1, we then get a new error.

Peer certificate cannot be authenticated with given CA certificates

This is currently still an open issue it seems (see #10146).

The term ‘Resolve-DnsName’ is not recognized as the name of a cmdlet, function, script file, or operable program

as this relies on .Net and has not yet been ported. So it seems more likely that it might work with v7 but there is that other string problem

Exception calling “CreateTemporaryFileInGuest” with “5” argument(s): “Failed to authenticate with the guest operating system using the supplied credentials.”

Can VIX and or your script work on from Linux powershell ?

I’m not convinced that the error you mention is related to the ‘multiple’ mode.
That looks more like a VM that has just been created/removed, and where the VirtualMachine object that is passed to the function (the value on the VM parameter) has not been refreshed since.

Something like this

$sInvoke = @{
VM = $vm
ScriptType = 'bash'
ScriptText = 'sudo bash -c "sleep 10; reboot now" &'
GuestUser = $user
GuestPassword = $pswd
}
Invoke-VMScript @sInvoke
