Question

Query Members of local Administrators Group

Asked by: ptea

Hi there,

I have to analyse the members of the local Administrators group on 500+ of servers. I want to do that with powershell & WMI. So I found the Win32_GroupUser Class for this query - but this doesn't work. There is a KB-articel available about this - but the solution described in the KB doesn't work (http://support.microsoft.com/kb/302857). Any ideas?

Thx - cheerio

gc C:\servers.txt | gwmi -query (SELECT * FROM Win32_GroupUser WHERE GroupComponent = "Win32_Group.Domain=\"BUILTIN\"Name = \ "Administrators\") | export-csv C:\localADM.txt

Try this.

gc C:\servers.txt | % { ([ADSI]"WinNT://$_/Administrators,group").psbase.Invoke("Members") | % {$_.GetType().InvokeMember("Name",'GetProperty',$null,$_,$null)} }

thx - using ADSI Provider did the trick.

gc C:\servers.txt | % { ([ADSI]"WinNT://$_/Administrators,group").psbase.Invoke("Members") | % {$_.GetType().InvokeMember("Name",'GetProperty',$null,$_,$null)} } | set-content C:\localADM.txt

you got the points - may I ask you a second question? The output lists all members of the local admin group as requested. But in the output I don't see on which server the members are.Is it possible to set the servername in front of the member seperated by a comma?

Like this

ServerName,Member

 

by: LearnctxPosted on 2009-09-25 at 05:00:39ID: 25422096

So you want it as:

server1,membera
server1,memberb
server2,membera
server2,memberb

Or are you after it as:

server1,membera,memberb
server2,membera,memberb

This will output it the first way. Might make it a bit more readable too.

Get-Content C:\servers.txt | `
Foreach-Object {
    $server = $_
    ([ADSI]"WinNT://$server/Administrators,group").PsBase.Invoke("Members") | `
    Foreach-Object {
        "$server,$($_.GetType().InvokeMember("Name",'GetProperty',$null,$_,$null))"
    }
} | Set-Content C:\localADM.txt

Hi Learnctx

Sorry I am very new to powershell. You script works very well for:
server1,membera
server1,memberb
server2,membera
server2,memberb

But if I would like it in the format of:
server1,membera,memberb
server2,membera,memberb

How would I do this?
