Try this:

$VMList = Import-CSV -Path C:\vmw_scripts\test.csv
$vcenter = "myvcenter"
connect-viserver $vcenter
foreach ($vm in $VMList) {
     Get-Tag $vm.tag | New-TagAssignment -Entity $vm.vm
}

thanks, but this them prompts for the Tag and even after I put it in, I get further errors

Supply values for the following parameters:

Just curious, can you run Get-Tag alone with no errors - should produce a list of all tags in your environment.

If you can, is the Application_Services tag in there and spelled the same as your input?

[bryanvaneeden]

We've been having the same errors for ages on all cmdlets that have anything to do with tags. Did you ever fix it? I started a case now, just want to see this fixed.

I think this started when they moved from PowerCLI 6.5 to Powershell Modules...

[kwhornlcs]

Are you getting the error on the Get-Tag run by itself, or when it's qualified?

[bryanvaneeden]

I'm getting the error on all "tag" related cmdlets, such as Get-VM -Tag "TAG", Get-Tag, Get-TagCategory. Doesn't really matter. Even with a difference powershell version, different logins and administrator@vsphere.local login...Still nothing on the case, VMware is still working on it.

[bryanvaneeden]

An update on this:

The case is still going, it's taking ages for them to help me/us on this.

It seems however that when we use the Tag cmdlets, we are getting some sort of connection error on port 7444 (STS token service). Not really sure why though because on other stations with the same network access, but with the older PowerCLI instead of Powershell modules it's working fine as it should.
