Unable to make a VS2005 COM API call from a web service because CoInitializeSecurity is already called by the .NET framework? Thats where CoSetProxyBlanket comes.

STDMETHODIMP CVSHelper::SetGuestParam(BSTR ServerName, BSTR VMName, BSTR ParamName, BSTR ParamValue, BSTR* ErrorDesc)

Q: Struggling with error ".ps1 cannot be loaded because the execution of scripts is disabled on this system. Please see "get-help about signing" for more details." while executing .ps1 powershell script file command prompt using powershell.exe?

A: Type C:\>Powershell.exe Set-ExecutionPolicy RemoteSigned  and press enter. Then execute your .ps1 file. - C:\>powershell.exe helloworld.ps1

Q: While executing helloworld.ps1 script returns immediately without waiting for me to see the output printed. Is there anything like getch() or cin ?

A: Yes, Powershell.exe –noexit &"c:\My scripts\helloworld.ps1"

Q: How to disable Network Card/NIC using powershell.

A:

$adapters=Get-wmiobject win32_NetworkAdapter | where {$_.AdapterType -like 'Ethernet*'}; 

foreach ($adpter in $adapters)

{

 $adpter.Disable();

}

$adapters=Get-wmiobject win32_NetworkAdapter | where {$_.PhysicalAdapter -eq 'true'};

foreach ($adpter in $adapters) { $adpter.Name };
