#powershell Script: Find Active Directory User II

Find-AdUserII is one of the many PowerShell functions/utilities in my personal script toolbox repository designed to help simplify the management and administration of just about any Active Directory Directory Services (AD DS) environments.

This self-explanatory utility works in PowerShell v2.0 and higher without any dependency on the AD PowerShell Module or other third party add-on. It accepts displayname as a parameter; you can customize the search criteria to any supported AD user attributes, for example. With the (auto) discovered forest/domain names, the function performs LDAP searches across multiple domains in your entire AD forest automagically (thanks to the .NET Framework). Enjoy!

This self-explanatory utility works in PowerShell v2.0 and higher without any dependency on the AD PowerShell Module or other third party modules. It accepts SamAccountName as a parameter; you can customize the search criteria to displayname or any supported AD user attributes for example. You don’t even need to know or specify the domain name if your AD environment is a straightforward single forest single domain setup. Enjoy!

Zürich PowerShell Training Kurs/Course (from May 2017)

PowerShellThe bad news is that I will miss another year of PowerShell Europe Conference in Hanover, Germany (2 – 5 May 2017). The very excellent news though is that I shall deliver and teach a private PowerShell 5.x course* to the biggest number one Swiss bank in the country, ranked as one of the top Fortune 500 global financial services institution worldwide.

How can I participate in or organize private (customized) lessons then? Simple really. Contact me for more information today. Or you can sign-up for any of my popular public PowerShell, Microsoft Windows Server 2016, MCSA certificate or specialized cloud training classes covering beginners to advanced levels:

Hyper-V: The operation cannot be performed while the object is in use (Windows Server 2016 / Windows 10)

You have a number of virtual machines running on your Windows Server 2016, Windows 10 or Windows Server 2008 R2 Hyper-V system. As soon as you try to start another VM in the Hyper-V Manager console or Start-VM virtmachine via PowerShell, a rather cryptic message keeps preventing you from doing so:

[Window Title]
Virtual Machine Connection

[Main Instruction]
The application encountered an error while attempting to change the state of ‘virtmachine’.

[Content]
‘virtmachine’ failed to change state.

The operation cannot be performed while the object is in use.

[Close]

To resolve this, disassociate any other VM from “Physical CD/DVD device” under media before you retry the operation on the failed VM.

Hyper-V: Virtual Machine failed to change state (Windows Server 2016 / Windows 10)

When you try to Apply a previously saved Checkpoint (snapshot) to a virtual machine in Hyper-V running Windows Server 2016, Windows 10 or Windows Server 2012 R2, a bizarre error message consistently appears even with full administrative rights on the machine:

[Window Title]
Virtual Machine Connection

[Main Instruction]
The application encountered an error while attempting to change the state of ‘virtmachine’.

[Content]
‘virtmachine’ failed to change state.

The operation is not supported.

[Close]

If restarting the “Hyper-V Virtual Machine Management” (vmms) and “HV Host Service” (HvHost) service does not help, a cold machine reboot should fix this rather strange issue.

Skype for Business Server 2015 – Windows Server 2016 and PowerShell 5.1 Support

Although Windows Server 2016 has been officially released since 26 Sep 2016 (Ignite conference in Atlanta), it is still not listed as a supported server operating system platform to install or operate Skype for Business Server 2015.  Likewise, this applies to domain controllers in the Active Directory environment.

Per “Server requirements for Skype for Business Server 2015” (TechNet – Topic Last Modified: 2017-02-23):

Windows Server 2016 is not included in this list right now, but we’re planning to add it as a supported option after Skype for Business Server Cumulative Update 5 is released. Until then, please don’t try to use Windows Server 2016 as an OS for your Skype for Business deployment today, as it’s not yet supported, and we don’t recommend it. And check back to this page once the cumulative update is released to confirm Windows Server 2016 is added to our supported list at that time.

Additionally, PowerShell 5.1 is delivered in Windows Server 2016 and Windows 10 Anniversary Update (Build 1607). On supported legacy and down-level Windows operating systems, you can apply Windows Management Framework 5.1 (KB3191565) to update to this current version. Nevertheless, WMF 5.1 is marked as incompatible with Skype for Business Server 2015 (or for that matter Lync Server 2013 and 2010).

The golden rule “If it ain’t broken, don’t fix it” should apply (particularly on live production systems)!
