Posted by: | January 31, 2016 Comments Off on Scripting Game puzzle – – January 2016 |

Here’s how I’d solve the puzzle function get-starttime {     [CmdletBinding()]     param(         [parameter(                 ValueFromPipeline=$true,                 ValueFromPipelineByPropertyName=$true)]         [Alias(‘CN’, ‘Computer’)]         [ValidateNotNullOrEmpty()]          [string[]]$computername = $env:COMPUTERNAME     )         PROCESS {             foreach ($computer in $computername){             $props = [ordered]@{                 ComputerName = $computer                 StartTime = ”                 ‘UpTime (Days)’ […]

PowerShell editing options

Posted by: | January 28, 2016 Comments Off on PowerShell editing options |

I’ve used the ISE since it first appeared in PowerShell 2.0 but there are a couple of recent annocements that increase your code editing options   ISE previews will become available out of band rather than being tied to WMF/OS releases http://blogs.msdn.com/b/powershell/archive/2016/01/20/introducing-the-windows-powershell-ise-preview.aspx   The preview ISE is a module you can download from the PowerShell […]

Which filter

Posted by: | January 27, 2016 Comments Off on Which filter |

Get-ADUser has 2 filter parameters. The –Filter takes a PowerShell syntax filter e.g. Get-ADUser -Filter {Name -eq ‘Richard’} The –LDAPfilter takes an LDAP search filter e.g. Get-ADUser -LDAPFilter "(Name=Richard)" Mixing them up will ensure you don’t get the results you want

Rescuing IE favourites

Posted by: | January 26, 2016 Comments Off on Rescuing IE favourites |

I received the new Windows Insider Windows 10 build over the wekend and have just discovered that installing it wiped out my IE favourites – or at least those in folders.   I’d copied my favourites to Microsoft Edge when installing Windows 10 so I can copy everything back   IE favourites are stored at […]

FQDN

Posted by: | January 26, 2016 Comments Off on FQDN |

How do you find the FQDN of the machine you’re using.  The simplest way is to combine a couple of environmental variables: PS> "$env:COMPUTERNAME.$env:USERDNSDOMAIN" SERVER02.MANTICORE.ORG   If you like using CIM (and who doesn’t) you can try this PS> Get-CimInstance -ClassName Win32_ComputerSystem | >> select @{N=’FQDN’; E={"$($_.DNSHostName).$($_.Domain)"}} >> FQDN —- server02.Manticore.org   This could easily […]

CDXML filter parameters

Posted by: | January 24, 2016 Comments Off on CDXML filter parameters |

I was recently asked about adding a filter parameter to a cmdlet created through CDXML. If you’ve not seen it before (see PowerShell and WMI Chapters 18 & 19 from www.manning.com) CDXML allows you to creat ecmdlets by wrapping a WMI class in some simple XML.   The resultaing CDXML (Cmdlet Definition XML) is thn […]

Setting external time source in AD

Posted by: | January 18, 2016 Comments Off on Setting external time source in AD |

The PDC emaulator in the root domain of your AD forest should point to an external time source. For some odd reason the PDC emulator in my lab wasn’t doing that. Easily remedied: ## ## set external time source ## set server type to NTP Set-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Services\W32Time\Parameters -Name Type -Value ‘NTP’ Set-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Services\W32Time\Config […]

WMF 5.0

Posted by: | January 17, 2016 Comments Off on WMF 5.0 |

If you follow the PowerShell Team blog – http://blogs.msdn.com/b/powershell/ (and if you don’t you should) you’ll know that the WMF 5.0 RTM downloads were pulled just before Christmas. This was due to a bug that reset the module environment.   A comment on the blog – http://blogs.msdn.com/b/powershell/archive/2015/12/23/windows-management-framework-wmf-5-0-currently-removed-from-download-center.aspx – from the team indicates that it’s likely […]
