Title: Remote Group Member Query
Author: user
in PowerShell how can i call the command below across an array of server names. right now, it appears i have to login via an RDP session Get-LocalGroupMember -Group "Administrators"

You can run the `Get-LocalGroupMember` command on multiple servers remotely using PowerShell's `Invoke-Command`. Here's a script that allows you to loop through an array of server names and execute the command remotely:

### Example PowerShell Script:
```powershell
# Define your array of server names
$servers = @('Server1', 'Server2', 'Server3')

# Loop through each server and run the Get-LocalGroupMember command
foreach ($server in $servers) {
    try {
        Invoke-Command -ComputerName $server -ScriptBlock {
            Get-LocalGroupMember -Group "Administrators"
        } -Credential (Get-Credential) | ForEach-Object {
            # Output the members with the server name for context
            [pscustomobject]@{
                ServerName = $using:server
                MemberName = $_.Name
                MemberSID  = $_.SID.Value
                MemberType = $_.ObjectClass
            }
        }
    }
    catch {
        Write-Host "Failed to connect to $server" -ForegroundColor Red
    }
}
```

### Explanation:
1. **Server Array**: Replace the server names with your actual list of server names in `$servers`.
2. **Invoke-Command**: This runs the `Get-LocalGroupMember` command on each server in the array using PowerShell Remoting.
3. **Credential Prompt**: The script uses `Get-Credential` to prompt for credentials when running the remote commands.
4. **Error Handling**: The `try/catch` block helps handle any connection failures to servers.

### Requirements:
- **PowerShell Remoting** needs to be enabled on the target servers.
- You need to have appropriate permissions to query the local groups on each remote server.

is there a wmi query to get the same information

Author: ChatGPT
Yes, you can use a WMI query to retrieve members of the "Administrators" group, though it's a bit more involved compared to the `Get-LocalGroupMember` cmdlet. The WMI class `Win32_GroupUser` can be used to query group members. Below is how you can query the "Administrators" group on remote computers via WMI:

### Example WMI Query in PowerShell:

```powershell
# Define your array of server names
$servers = @('Server1', 'Server2', 'Server3')

# Loop through each server and run the WMI query
foreach ($server in $servers) {
    try {
        $groupMembers = Get-WmiObject -Class Win32_GroupUser -ComputerName $server -Filter "GroupComponent='Win32_Group.Domain=""$server"",Name=""Administrators""" -Credential (Get-Credential)

        foreach ($member in $groupMembers) {
            $memberPath = $member.PartComponent
            $memberInfo = $memberPath -split '=' | Select-Object -Last 1
            $memberName = $memberInfo.Trim('"')

            [pscustomobject]@{
                ServerName = $server
                MemberName = $memberName
            }
        }
    }
    catch {
        Write-Host "Failed to connect to $server" -ForegroundColor Red
    }
}
```

### Explanation:
1. **WMI Query**: The `Get-WmiObject` cmdlet queries the `Win32_GroupUser` class, filtering by the "Administrators" group on the remote computer.
2. **Filter**: The `GroupComponent` filter specifies the domain and the group name. Here, we are assuming the group name is "Administrators", and we dynamically insert the server name as the domain.
3. **Extract Member Names**: The results from WMI return a `PartComponent` string, which contains the member details. The script extracts the member name from this string using a split operation.
4. **Error Handling**: The `try/catch` block helps handle connection failures.

### Requirements:
- **WMI Access**: You need WMI access on the target servers.
- You must have appropriate permissions to query local groups via WMI on the remote servers.

This approach can serve as an alternative to the `Get-LocalGroupMember` cmdlet, particularly in environments where PowerShell Remoting is not enabled or desired.
