Need a script to list all servers in Active Directory.  From Windows 2000 Server all the way up to and including Windows Server 2008 R2.  Need to make sure all Editions are included.  e.g. Advanced, Standard, Enterprise, Datacenter and 32-bit and 64-bit versions.

Thanks

You can use the quest AD cmdlets

get-qadcomputer | where{$_.operatingsystem -match "Server"} | select name, operatingsystem | export-csv c:\server.csv

or if they are all in the same OU

get-qadcomputer -searchroot "OU=Servers,DC=Domain,DC=Local"


depending on what information you may need to do a wmi query.

$servers = get-qadcomputer -searchroot "OU=Servers,DC=Domain,DC=Local"
Foreach ($Server in $servers){
gwmi -computer $server -class win32_operatingsystem | select name, producttype
}

My problem is I do not know if PS is installed on any server or if I will be allowed to install PS.

I just emailed the customer to find out.  It would be nice if PS is installed or they give me permission to install it.

All I need is the "cn" attribute (according to the test dsquery I ran) which should be the server's hostname.

if you just need to CN you can install powershell on a workstation that is a member of the domain.

depending on the number of servers you may need to use the -sizelimit switch

get-qadcomputer -sizelimit 0 | where{$_.operatingsystem -match "Server"} | select DN

This will do pretty much the same thing but utilizes the built in AD Powershell Console for 2008 R2 if you have a DC that uses that.
get-adcomputer -filter * -properties operatingsystem | where
{$_.operatingsystem -match "Server"} | select name, operatingsystem > c:\servers.csv

Open in new window

That should be

get-qadcomputer -sizelimit 0 | where{$_.operatingsystem -match "Server"} | select name

"My problem is I do not know if PS is installed on any server or if I will be allowed to install PS."
Check if you have a Windows 2008 R2 Domain Controller. If you do, you have the MS AD Powershell Console already.

KenMcF, where do I get and how to I install the Quest AD cmdlets?

I have two other questions I posted this morning.  This file of server names will be used by another script to list all local groups on each server and the members of each group including nested groups.

acbrown2010, sorry didn't realize I had to do this:

When the Active Directory module is installed, to start it click Start, point to Administrative Tools, and then click Active Directory PowerShell

I wound up just using ADFind to do this since the AD and all DCs were 2000.
