Create NIC team using all interfaces

Question

I'm trying to put together a function that will take all the physical NICs on a server and team them together. I'm not even sure where I found the example, but here is the code I have below. This seems like it should be much simpler and that I'm missing
something.
# Create a network team using switch independent teaming and Hyper-V port mode
Function TeamSetup ($teamName)
$adapters = Get-NetAdapter
$nicList = @()
Foreach ($nic in $adapters)
$nicList += $nic.Name
New-NetLbfoTeam $teamName –TeamMembers ($nicList) –TeamNicName $teamName -TeamingMode SwitchIndependent -LoadBalancingAlgorithm HyperVPort

Answer 1

This actually seems to be some sort of problem with running these commands as part of a script. If I enter my original code directly into PowerShell line-by-line, it works as expected. As does the same command using the * wildcard instead of the $nicList
variable. No matter how I change the code in the script, it fails with this error:
New-NetLbfoTeam : There are no teamable NetAdapters on the system matching TeamMembers parameter
At C:\Script.ps1:190 char:2
