WSUS Administrator Module

This has been a few months in the making to get what I think is a decent build of my WSUS Administrator Module.  My goal with this module was to make something that provided enough use for most aspects of WSUS administration.  With that, I have put together 40 advanced functions that provide access to various parts of WSUS.  Some of these are commands to query different parts of wsus, such as clients, updates, server configurations, etc…  Other parts allow for making configuration changes or approving/disapproving updates, creating or removing Target groups and adding/removing clients from Target groups.  Some of the commands, such as ones that approve/decline updates, adds/removes a group, etc… have the whatif and confirm capabilities so you can verify that everything will happen as intended.

I have spent the last week testing it and working out all of the bugs, but most likely there are still some quirks here and there.  I would appreciate any comments, both positive and negative as anything said will help to make the next version of this module better.  I already have a list of probably 4 or 5 things that I want to add to this module for the next version.

So without further ado, I will walk through a few of the basic things in my module…

Importing the module

IMPORTANT!! You must have the WSUS Administrator Console installed on whichever computer that you will be running this function from. Download available here.

Be sure to save the module off as a .psm1 file so you can run the Import-Module cmdlet. Once you import the module, it will display a message telling you a couple of things that you can do to get started. I modeled this after the PowerCLI module as it seemed like a pretty good idea to show a couple of key things such as finding all of the commands available and how to make the initial connection to the server.

Available Commands

As I said before, I currently have 40 available advanced functions to perform a variety of tasks in WSUS. Below is a list of the commands:

Add-WSUSClientToGroup
Approve-WSUSUpdate
Connect-WSUSServer
Convert-WSUSTargetGroup
Deny-WSUSUpdate
Disconnect-WSUSServer
Get-WSUSChildServers
Get-WSUSClient
Get-WSUSClientGroupMembership
Get-WSUSClients
Get-WSUSClientsInGroup
Get-WSUSCommands
Get-WSUSContentDownloadProgress
Get-WSUSDatabaseConfig
Get-WSUSDownstreamServers
Get-WSUSEmailConfig
Get-WSUSEvents
Get-WSUSGroup
Get-WSUSGroups
Get-WSUSServer
Get-WSUSStatus
Get-WSUSSubscription
Get-WSUSSyncHistory
Get-WSUSSyncProgress
Get-WSUSUpdate
Get-WSUSUpdateCategories
Get-WSUSUpdates
New-WSUSGroup
Remove-WSUSClient
Remove-WSUSClientFromGroup
Remove-WSUSGroup
Remove-WSUSUpdate
Resume-WSUSDownloads
Resume-WSUSUpdateDownload
Set-WSUSEmailConfig
Start-WSUSCleanup
Start-WSUSSync
Stop-WSUSDownloads
Stop-WSUSSync
Stop-WSUSUpdateDownload

Making Initial Connection to WSUS Server

To make the initial connection to the WSUS server, use the Connect-WSUSServer function. This will allow you to use the other advanced functions that are available within this module.

Untitled

Now that the connection has been made, we can begin looking at a couple of commands that will probably be getting a fair amount of use.

Viewing Updates

The Get-WSUSUpdates advanced function will grab all of the updates, so be careful using it as it may take a while to grab every update. Using the following command, I can pull the first 5 updates.

Get-WSUSUpdates | Select -first 5 | Select Title, KnowledgeBaseArticles, UpdateClassificationTitle

Untitled

If you want to look for a specific update, you can use Get-WSUSUpdate to accomplish this. This works much faster and is more helpful for filtering for specific updates.

Get-WSUSUpdate -Update "819639"

Untitled

WSUS Target Groups

You can view the current WSUS Target groups using the Get-WSUSGroups function.

Untitled

Creating a new WSUS Target group is as simple as using the New-WSUSGroup command.

New-WSUSGroup -Group "NewWSUSGroup"

Untitled

And removing a group using Remove-WSUSGroup.

Remove-WSUSGroup -Name "NewWSUSGroup"

Untitled

Approving and Declining WSUS Updates

There are a couple of ways to both approve and decline updates within this module.  The first way is supplying a string value and have the command search for and approve/decline the updates.

For approving and update, you have a few other things that are required in order make the approval successful.  The first is to supply a group that the update will be approved for. Second, you must provide an Action type  for the update approval, typically “Install”.  The third and not a required option is to provide a deadline for the update.

Approve-WSUSUpdate -Group "Domain Servers" -Update "819639" -Action Install

Untitled

Declining is much easier and only requires the update string to be entered.

Deny-WSUSUpdate  -Update "819639"

Untitled

Besides using the string method, both the Approve-WSUSUpdate and Deny-WSUSUpdate accepts input via the pipeline and allows you to use objects as well.  So combining the Get-WSUSUpdate or Get-WSUSUpdates with the approving or declining of updates will work just as well.

Get-WSUSUpdate -Update "819639" | Approve-WSUSUpdate -Group "Domain Servers" -Action Install

Untitled

Get-WSUSUpdate -Update "819639" | Deny-WSUSUpdate

Untitled

WSUS Synchronization

I have a few advanced functions that work with synchronization, such as pulling synchronization events with Get-WSUSSyncHistory, starting a manual synchronization with Start-WSUSSync and finding the current status of a synchronization using Get-WSUSSyncProgress.

Get-WSUSSyncHistory | select -first 1

Untitled

Start-WSUSSync

Untitled

Get-WSUSSyncProgress

Untitled

There is a parameter switch with Get-WSUSSyncProgress and Start-WSUSSync called ‘monitor’ which starts a background job that will alert you with a popup message stating that the synchronization has been completed.

This module is available for download from both the Script Repository and at Poshcode along with the code being available below.

Script Repository

Poshcode

Currently, the code I submitted to PoshCode appears to be getting truncated.  I left some feedback asking about this and am waiting on a reply. I will try again to re-post the code and see if it works, and if so, I will remove this message.

21NOV2010: Updated code for Connect-WSUSServer to allow for adding what port you want to connect to on the WSUS Server in case the server was configured for a port other than the default ports.

    An interesting and promising article for some broken WSUS systems I’m working with. Do you know where I can locate a copy of the module that contains these commands (wsusadmin-module.psm1) for WSUS 3.0 SP2? All references I can find point me to PoshWSUS, which has different commands and syntax.

    Thanks!

    I work at a datacenter and it works great for one of my customers but for another when I do connect-poshwsusserver computername I get error Unable to connect to computername!

    I haven’t found any useful help articles online.

    Hi,

    very nice and useful module ! excellent job 🙂
    quick idea/suggestion if you are interested in…
    Could be useful to check the approval status per KB to know in which WSUS groups the KB has been approved or not…
    let me know your thoughts
    Cheers,
    Michael

    Some problems with ”
    Get-Wsusclientgroupmembership -Computer “$servername” ”
    If the servename is identical with some characters you get to much information/groups from all server.
    Example:
    Servername is a)serverastest and b)serverastest2.msds.insite
    $servername=serverastest
    First you get all information for both server.
    If you set $servername=servertest2.msds.insite you got only the information about this server.

    I think the function doesn’t search the servername. The function works with wildcards as a string and not with the correct servername…

    Can you help me for a better version, please.

    I’d recommend splitting this module up into different source files. The main module file could be the “installer” for it, referencing the “real” source files using dot-sourcing.

    I used this method in the current module I’m working on, and it works great. Besides making module maintenance easier, it also adds a level of professionalism to the module, rather than sticking everything inside a single file.

  15. Wow looks promising, I will definitely give it a try.
