Check Windows Updates

sometimes you need to check does a server has a update, here the powershell script:
param ($myServer,$myHotFix)
$kb=$false
$myKBs=icm $myServer {get-hotfix}
foreach ($item in $myKBs)
{
    if ($item.HotFixId -eq $myHotFix){
        $item
        $kb=$true}
}
if ($kb -eq $false) {write "No such KB"}

It can be checked from one line:
icm "servername" {get-hotfix|where {$_.HotFixId -eq "KBnumber"}}

Install .Net 3.5 on Windows 2012 R2 server

To install .Net 3.5 on Windows 2012 R2 server you need to mount Windows 2012 R2 dvd and point installation on "dvd"\sorce\sxs directory - in Powershell it will be like this:

 

Add-WindowsFeature NET-Framework-Core -Source d:\sources\sxs

Make-USB-Bootable

# Before running the script check USB key disk number with get-disk command, run the script from

# elevated shell

# robocopy "source" "destination" /mir /xd "System Volume Information" "$Recycle.bin"

param($disk_number,$DriveLetter)

Clear-Disk -Number $disk_number -RemoveData

New-Partition -DiskNumber $disk_number -UseMaximumSize -IsActive -DriveLetter $DriveLetter

Format-Volume –FileSystem NTFS –DriveLetter $DriveLetter

set-location $env:windir\system32

SharePoint Search problem after migration

After migrating from WSS 3.0 to Foundation 2010 cannot search inside a document.
Basically it shows in the document property "Pending", so the document waiting for approval.
Created a small PowerShell script to approve all documents on a site:
________________________________________________________________________

$mySite=Get-SPSite "http://yoursite"

$myWebSub=$mySite.AllWebs

foreach ($myWeb in $myWebSub)

{

    $myWeb=Get-SPWeb $myWeb.url

    $myWeb.url

    $myLIb=$myWeb.lists|where {($_.BaseTemplate -eq "DocumentLibrary")}

    foreach ($lib in $myLib)

    {

        $lib.Title

        $myDocs=$lib.Items

        foreach ($doc in $MyDocs)

        {

            $doc.name                             # only for information

            $doc.file.level                       # only for information

            if (($doc.file.level -eq "Draft") -or ($doc.file.level -eq "Pending")){$doc.file.Approve("script")}

            $doc.file.level                        # only for information

           

        }

    }

}

Powershell script to enumerate SMTP addreses and alieses

I used the script to collect the information from Exchange 2003 for migration to Exchange 2010, but it can be used for collecting the information from Exchange 2010 (but it can be easy done with Poweshell snapin for Exchange). For setup PowerShell environment for Exchange 2010 you can try my blog page powershell-ms-exchange-part1.

PowerShell SharePoint 2010 Backup

I need to schedule SharePoint 2010 Backup (site):
First create a PowerShell script in Notepad:
Backup-SPSite -Identity http://wss-08r2 -Path "\\servername\sharepoint2010\one\wss-08r2.bak" -Force

name the file - backup.ps1

Second:
Under folder C:\Windows\System32\WindowsPowerShell\v1.0 create profile.ps1 file it will be default profile for all users on the SharePoint front end server, edit the file by adding -

Add-PSSnapin Microsoft.SharePoint.PowerShell

And save the file.

Third:

Create a scheduled job and in Action tab put:

Action: powershell.exe

Add arguments: -command "PATH\backup.ps1"

where is PATH - path to the script file.
