Wireshark – The NPF driver isn’t running
As soon as I opened my wireshark, the message popped up: “The NPF driver isn’t running…
As a local administrator do this:
net start npf
Now go back and open WireShark. Everything will be ok 😉

How to schedule a Windows Powershell script
Couple of things to know
There are two main things that you have to do to schedual Powershell scripts.
- Allow Interactive Commands using set-executionpolicy command.
- Put Powershell script in a ".ps1" file. You can use any text editor to make this.
The first thing you need to do is make sure that Powershell is set to execute Powershell scripts, instead of only allowing interactive commands to be run in the Powershell environment.
Type the following at the Powershell command prompt:
set-executionpolicy RemoteSigned
This will allow the system to run Powershell scripts that are created locally (Remote Powershell scripts that may be downloaded must be signed).
Once this is done, you can create your Powershell script using notepad. Just make sure you name the file with an extension of .ps1 . Now to run the script outside of its Powershell environment you type a command similar to the following:
powershell -command "& 'MyScript.ps1' "
Just put the above command into a .bat or .cmd file and schedule it like you would normally schedule a script to be run with Windows task scheduler.
Step By Step – How to Enable Remote Desktop Connections on Server Core 2008
How to Enable Remote Desktop Connections on Server Core 2008
At the command prompt type:
CD\Windows\System32 cscript scregedit.wsf /ar 0
If you typed it correctly it will display:
Microsoft Windows Script Host Version 5.7 Copyright (C) Microsoft Corporation. All rights reserved. Registry has been updated..
Next type:
cscript scregedit.wsf /ar /v
If you did things correctly the server will output:
Microsoft (R) Windows Script Host Version 5.7 Copyright (C) Microsoft Corporation. All rights reserved. System\CurrentControlSet\Control\Terminal Server fDenyTSConnections View registry setting. 0
Next you will have to make sure that the firewall on the server has the propper ports opened to allow remote connections through. You do this by running another command.
C:\Windows\System32>netsh firewall set service type=remotedesktop mode=enable
If done correct it will output: ok
Hyper-V Virtualization Server version Upgrade available
Warning on Hyper-V hosts under SCVMM
I have seen this documented in a couple of places now – but I also see a number of people still wondering why this is happening and how to stop it, so I thought I would post it here too. When you first add a Hyper-V host to SCVMM 2008 you may see a warning icon displayed with the message "Needs Attention" and "Virtualization service version status is not up-to-date". To get rid of this alert there are three updates that need to be applied to the Hyper-V server:
- KB950050: This is the RTM update for Hyper-V
- KB956589: This is an update to Hyper-V specifically for SCVMM compatibility
- KB956774: This is an update to the Background Intelligent Transfer Service (BITS) client in Windows Server 2008
Once you have these three updates installed everything should come up green.
