PowerShell Basics for Dummies - ConvertTo-Html

PowerShell Basics for Dummies - ConvertTo-Html

ConvertTo-Html:

• Converts Microsoft .NET Framework objects into HTML that can be displayed in a Web browser.

• The ConvertTo-Html cmdlet converts .NET Framework objects into HTML that can be displayed in a Web browser. You can use this cmdlet to display the output of a command in a Web page.

• You can use the parameters of ConvertTo-Html to select object properties, to specify a table or list format, to specify the HTML page title, to add text before and after the object, and to return only the table or list fragment, instead of a strict DTD page.

• When you submit multiple objects to ConvertTo-Html, Windows PowerShell creates the table (or list) based on the properties of the first object that you submit. If the remaining objects do not have one of the specified properties, the property value of that object is an empty cell. If the remaining objects have additional properties, those property values are not included in the file.

Get-EventLog -LogName "Windows PowerShell" | ConvertTo-Html > PSEventlog.htm

• The command sends the HTML code to the PSEventlog.htm file.

• All Signed — If the execution policy is set to All Signed then scripts will be allowed to run, but only if they are signed by a trusted publisher.
• Remote Signed — If the execution policy is set to Remote Signed, any PowerShell scripts that have been locally created will be allowed to run. Scripts created remotely are allowed to run only if they are signed by a trusted publisher.
• Unrestricted — As the name implies, Unrestricted removes all restrictions from the execution policy.

Four levels of security exist:

• 1. Restricted — Restricted is the default execution policy and locks PowerShell down, so that commands can be entered only interactively. PowerShell scripts are not allowed to run.
• 2. All Signed — If the execution policy is set to All Signed then scripts will be allowed to run, but only if they are signed by a trusted publisher like Microsft etc.
• 3.Remote Signed — If the execution policy is set to Remote Signed, any PowerShell scripts that have been locally created will be allowed to run. Scripts created remotely are allowed to run only if they are signed by a trusted publisher like Microsoft.
• 4. Unrestricted — Unrestricted removes all restrictions from the execution policy.

You can set an execution policy by entering the Set-ExecutionPolicy command followed by the name of the policy. For example, if you wanted to allow scripts to run in an All Signed manner you could type:

SCCM Interview Questions

SCCM Interview Questions

Does the Configuration Manager console support a 64-bit operation system?

Yes. The Configuration Manager console is a 32-bit program that can run on a 32-bit version of Windows and on a 64-bit version of Windows.

Are there new Active Directory schema extensions for System Center 2012 Configuration Manager?

No. The Active Directory schema extensions for System Center 2012 Configuration Manager are unchanged from those used by Configuration Manager 2007. If you extended the schema for Configuration Manager 2007, you do not need to extend the schema again for System Center 2012 Configuration Manager.

Have the site types changed from Configuration Manager 2007?

System Center 2012 Configuration Manager introduces changes to both primary and secondary sites while the central administration site is new site type. The central administration site replaces the primary site referred to as a central site as the top-level site of a multi-primary site hierarchy. This site does not directly manage clients but does coordinate a shared database across your hierarchy, and it is designed to provide centralized reporting and configurations for your entire hierarchy.

Can I join a pre-existing site to another site in System Center 2012 Configuration Manager?

No. In System Center 2012 Configuration Manager you cannot change the parent relationship of an active site. You can only add a site as a child of another site at the time you install the new site. Because the database is shared between all sites, joining a site that has already created default objects or that has custom configurations can result in conflicts with similar objects that already exist in the hierarchy.

Why can’t I install a primary site as a child of another primary site like I could in Configuration Manager 2007?

With System Center 2012 Configuration Manager, primary sites have changed to support only secondary sites as child sites, and the new central administration site as a parent site. Unlike Configuration Manager 2007, primary sites no longer provide a security or configuration boundary. Because of this, you should only need to install additional primary sites to increase the maximum number of clients your hierarchy can support, or to provide a local point of contact for administration.

Why do I need SQL Server for my secondary site?

In System Center 2012 Configuration Manager, secondary sites require either SQL Server, or SQL Server Express to support database replication with their parent primary site.
