SharePoint Sites and Pages Powershell Warmup Script

Very nice little script i created to warmup all PWA pages and workspaces.
Simply replace the SiteURL and the SitePages with your own values and place the code in a file named "SharePointWarmup.ps1".
Run the script in Powershell or Task Scheduler.

 $SiteURL = "http://intra/PWA/"  
 $SitePages =   
 Add-PsSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue   
 $timeout = 240000 #=4 min   
 Add-Type -ReferencedAssemblies "System.Net" -TypeDefinition @"   
 using System.Net;   
 public class WarmupWebClient:WebClient  
   private int timeout = 60000;   
   public WarmupWebClient(int timeout) {this.timeout = timeout;}  
   protected override WebRequest GetWebRequest(System.Uri webUrl)   
     WebRequest requestResponse = base.GetWebRequest(webUrl);   
     requestResponse.Timeout = this.timeout;   
     return requestResponse;   
 function HitPage($url)  
     Write-Host "Hitting page: $url"   
     $wc = New-Object WarmupWebClient($timeout)   
     $wc.Credentials = [System.Net.CredentialCache]::DefaultCredentials   
     $ret = $wc.DownloadString($url)   
   catch [Exception]   
     Write-Host "Failed to hit page. Message was: $($_.Exception.Message)"   
 foreach ($site in $SitePages)   
   $warmupSite = $SiteURL + $site  
 Write-Host "All sites have been hit"   

Of cause you want this script to be run on a timely schedule so remember to check out my other post on how to do exactly that Run Powershell from Task Scheduler .


  1. Hello, it's with great happiness that I tried your script!
    thanks for that great post.
    for those who will copy the script, be careful that powershell does not support space before the "@


  2. Another comment: what is your propose schedule to run such script? daily, hourly,each minute?

  3. Hi Jérome,
    Thank you for the correction with the @" (must be the HTML formatter that have added it).

    In a normal environment the IIS is configured to recycle at 02:00. So i would suggest to run the schedule on a daily basis between 03:00-08:00.
    However normally I just configure it to run every 3 hours to give a better user experience.

    Check IIS Recycle Schedule
    1. Open IIS Manager.
    2. In the Connections pane, expand the server node and click Application Pools.
    3. On the Application Pools page, select an application pool
    4. Click Recycling in the Actions pane.
    5. Select Specific time(s), and in the corresponding box type a time at which you want the application pool to recycle daily.

  4. thanks a lot for your quick answer! I really like it especially to keep excel services up and running!

Install DLL in GAC - Windows 2008/2012 (Using Powershell, No GacUtil.exe)

If you want to install a DLL in the GAC and do not have the GACUtil.exe available. Powershell is properly the easiest way to procede.

Before Powershell you would properly just drag the DLL file into the C:\Windows\Assembly but this option is usually not available anymore.

Powershell - Add DLL to GAC So to install a DLL file in the GAC simply execute the below Powershell script. Remember you migth want to run the Powershell prompt as an administrator.
[System.Reflection.Assembly]::Load("System.EnterpriseServices, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")$publish=New-ObjectSystem.EnterpriseServices.Internal.Publish$publish.GacInstall("c:\temp\MyDllFile.dll")iisreset
The first line adds a reference to the assembly we need to be able to mange the GAC.
The second and third lines retrives the GAC object and publish a new DLL file to it.
The last line resets the Internet Information Services. This is only needed if your DLL file is used in a websi…

Error occurred in deployment step 'Add Solution': Attempted to perform an unauthorized operation.

Received this error today when trying to create a SharePoint solution against a newly created site.

My first problem was the site was configured to use a port which was already used by another web site. Therefore the site could not start at all.

In my case both Default Web Site and SharePoint - 2000 was both using port 2000. Changing the port of Default Web Site and I was able to start the site.

However now I still received the same error message. When browsing the site I realized I did not have access to the site.

Giving access to my user and I was able to deploy the solution.

To sum up this post:
 - Check the site can start
 - Check the site can be browsed
 - Check your user have access to the site

SharePoint 2013 : Cannot connect to the targeted site.

On my Contoso environment I was trying to create a sandboxed solution. I have already configured my app domain and app management services. But when I tried to validate the site I got the following error message.

Cannot connect to the targeted site. This error can occur if the specified site is not hosted on the local system. SharePoint solutions work only with locally-installed versions of SharePoint Foundation or SharePoint Server. Remote development is supported only for apps for SharePoint 2013.
If you search around the internet you will find many people suggesting to change your host file from to the actual IP.

Solution However the solution, at least on a Contoso environment, is to type in the actual IP address in the host file.
(the IP is the special IP for Contoso, I have 2 network adapters)
And do not forget to clear/flush the DNS cache. Now the solution can be created and validates.
