How to check if a user is an administrator for a given server name?

Question

Using the username, I want to find a way to check if that user is an administrator for a given remote server.

I found the following function online but it only checks if the user is an admin for the local machine.

Any help is appreciated!

function Test-Administrator
{
$user = [Security.Principal.WindowsIdentity]::GetCurrent();
(New-Object Security.Principal.WindowsPrincipal $user).IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator)
}

Hi,
You might want to refer to this article:
https://devblogs.microsoft.com/scripting/check-for-admin-credentials-in-a-powershell-script/
Also PowerShell version higher than 5.1 (Windows Server 2016) contains Get-LocalGroupMember cmdlet.
$user = "$env:COMPUTERNAME\$env:USERNAME"
$group = 'Administrators'
$isInGroup = (Get-LocalGroupMember $group).Name -contains $user

Thanks for your time.
Best regards,
Danny
