How to rename, sort and organise files, based on filename using PowerShell.

The following PowerShell script takes a list of files in a given folder, creates a new folder based on the given filename, and moves the given file, into that fold.

foreach($file in (Get-ChildItem 'x:\vol\movies\renew' | Where {(-not $_.PSIsContainer) -and  (-not $_.PSIsContainer)})) 

{New-Item -Path (Split-Path $file.fullname) -Name (Split-Path $file.fullname -Leaf).ToString().Replace(".avi","") -ItemType Directory

Move-Item -Path $file.fullname -Destination "$(Split-Path $file.fullname)\$((Split-Path $file.fullname -Leaf).ToString().Replace('.avi',''))"}

How to Change Network Profiles with PowerShell?

 

Change Network Profile Using PowerShell

The three network profiles in Windows 10 are:

• Private: Computers on a private network can belong to a home group. Network discovery is turned on for private networks, which allows you to see other computers and devices on the network.
• Public: Designed to keep your computer from being visible to other computers around you and to help protect your computer from any malicious software from the Internet.
• Domain: It belongs to enterprise network. It’s controlled by network admin and can’t be selected and changed locally.

Change network profile using PowerShell in Windows 10.

1. Open PowerShell and run it as administrator. Then type “Get-NetAdapter” and press enter to see all network adapters.

2. To fine the network adapter profiles, type “Get-NetConnectionProfile” and press enter. You can specify the network connection with “-InterfaceAlias” parameter. It show only the exact network connection information.

Public Network Profile

The network category is public, so try to change to private network with “Set-NetConnectionProfile” cmdlet.

Note: It’s not possible to change the network adapter category to domain when there is no domain available. It’s only change Private network to public and public to private network using PowerShell. 
3. To change Public network to Private network, simply type “Set-NetConnectionProfile -InterfaceAlias Ethernet -NetworkCategory Private” and press enter.

4. To see the result, type “Get-NetConnectionProfile” or specify the network adapter name with “-InterfaceAlias” parameter.

Windows 8 and Wake on Lan

Wake on Lan (WOL) issues with Windows 8

Wake-on-LAN behavior in Windows 8
http://support.microsoft.com/kb/2776718

Windows 8:  In Windows 8, the default shutdown behavior puts the system into hybrid shutdown (S4) and all devices are put into D3. Remote Wake-On-LAN from hybrid shutdown (S4) or classic shutdown (S5) is unsupported. Network adapters are explicitly not armed for Wake-On-LAN in both the classic shutdown (S5) and hybrid shutdown (S4) cases because users expect zero power consumption and battery drain in the shutdown state. This behavior removes the possibility of spurious wakes when explicit shutdown was requested. As a result, Wake-On-LAN is only supported from sleep (S3) or hibernate (S4) in Windows 8.

To resolve this follow the below steps

To disable hybrid shutdown (S4) in Windows 8 (not recommended), use these steps:

1. Open the Power Options in Control Panel
2. Select “Choose what the power buttons do”
3. Uncheck “Turn on fast startup (recommended)"
4. Select "Save Settings"

Move DPM_SYSTEM_STATE to other location

When using Data Protection Manager to back-up the system state of your servers you will find that a folder with the name DPM_SYSTEM_STATE is created on your C:\ drive on the protected server. When disk space is insufficient to support this additional data, you can alter the location where this data is stored:

On the Protected Server:

• Edit the %system drive%\Program Files\Microsoft Data Protection Manager\DPM\Datasources\PSDataSourceConfig.xml file
• You will find the default the path is %system drive%\.
• Change it to the appropriate location and save the file.

On the DPM Server:

• Modify the Protection Group
• Run Consistency Check on the System State datasource

TechNet Webcast: Hyper-V: The Base of a Private Cloud

The term "cloud" refers to a new paradigm in the evolution of computing. It often entails running your servers, either internal or hosted, on virtual machines. In an IT career, the one constant is that you need to continually learn the new technologies to stay current. In this webcast, we cover the fundamentals of Microsoft’s technologies that support the private cloud. We overview Microsoft's Hyper-V virtualization technology and then dive deeper into the features of this hypervisor-based server virtualization technology. This webcast is heavily focused on demonstrations and has a Q&A session at the end.
