powershell – Find all computers in a domain or OU running a service

Sometimes you need to find all the computers on a domain that are running a certain particular service. By using Active Directory, supplying your canonical domain name, and define an output file, you can easily create a list of computers running a service.

First, start PowerShell as administrator, and import active-directory powershell components with the following command:

Import-Module ActiveDirectory

Then, open PowerShell ISE and copy in the following into a new .ps1 script:

$ou = "OU=Computers,OU=finance,DC=east,DC=contoso,DC=com"

$servers = Get-ADComputer -Filter * -SearchBase $ou | select-object 
-expandproperty name

Foreach ($server in $servers){
$Data = Get-Service -ServiceName *SAVService* -ComputerName $server | 
select machinename,name | sort machinename | format-table -AutoSize 

Write($Data) | Out-File .\machinesrunningSAVService.txt -Append
}

Run the script, and your output file will look similar to the following:

MachineName Name      
----------- ----      
hostname1   SAVService



MachineName Name      
----------- ----      
hostname2   SAVService



MachineName Name      
----------- ----      
hostname3   SAVService

Exchange 2010: Exchange Management Console (EMC) – Part 8

A quick overview of the Exchange Management Console, or EMC; a very capable management console accessed via the OWA web interface.

We can access the EMC through Outlook Web App. On the Exchange Mailbox server itself, you can get to OWA through the address https://localhost/owa

Note: I encountered an issue here. When first logging into OWA I received the following error message: “Your mailbox appears to be unavailable. Try to access it again in 10 seconds. If you see this error again, contact your helpdesk.”

My first instinct when I receive a message like this is to check services. Yes, as I suspected, upon viewing my primary Exchange server services, the Microsoft Exchange Server Information Store Service was not started. I started the service manually, logged into OWA again, and found I could now completely log in and see my OWA inbox.

Once inside the administrator’s mailbox, you can manage the organization by clicking on the Options drop-down in the upper right-hand corner, and then on “See all options…”

ManageOptions
Now that you’ve clicked into all of the options, you will want to change the Mail > Options: “Manage Myself” drop-down to “My Organization”. You are now in the Exchange Management Console.EMC

Once inside the EMC you have the following Options:

  1. Users and Groups – contains Mailboxes, Distribution Groups, and External Contacts
  2. Roles and Auditing – contains Administrator Roles, User Roles, and Auditing. There are some nice Auditing controls available here including * Run a non-owner mailbox access report… * Run a litigation hold report… * Run an administrator role group report… * Export Mailbox Audit Logs… * Export the Administrator Audit Log…
  3. Mail Control – contains Rules, Journaling, and Delivery Reports
  4. Phone and Voice – contains ActiveSync Access (Quarantined Devices and Device Access Rules); and ActiveSync Device Policy
Take note that Multi Mailbox Search (which is under mail control in RTM). RVAC, even the admin is not able to see the Multi Mailbox Search; you have the add the administrator into the Discovery Management Role Group. Once added to that group, you will see MultiMailbox search in the Administrators EMC.
