.NET Namespace-Powershell

All Scripts in this Blog written using .NET Namespace so we don't have the Module Dependency.

Now a days there are so many Modules are available in Powershell. For our daily operation those are very helpful.If we using built-in Module there are few challenges like If we are used "ActiveDirectory" Module; that module is available in Domain Controler or you need to install that manually. In this case if we want manage our AD; we need "ActiveDirectory" Module. That is the reason I am putting this topic in this blog. If you are used .NET namespace you don't need the Module.

If we are used .NET name space instead of Powershell Module which is available in all Windows 2008 System. Also we don't have any Module available in Windows 2008 for manageing the Microsoft PKI.

Given few important Namespaces those can make our life easier & we can write our own code without the Powershell Module.

1. We can manage our Active Directory

NameSpace

[System.DirectoryServices.ActiveDirectory]

Snap from ISE

Few one liner have been mentioned for manageing our Active Directory.

#DCs Inventory 
[system.directoryservices.activedirectory.domain]::GetCurrentDomain().DomainControllers | Select Name,IPAddress,OSVersion,SiteName | FT -AutoSize 
#Getting the Domain Functional level 
[system.directoryservices.activedirectory.domain]::GetCurrentDomain().DomainMode 
#Getting the Forest Functional level 
[system.directoryservices.activedirectory.forest]::GetCurrentForest().ForestMode 
#Getting the Trust 
[system.directoryservices.activedirectory.domain]::GetCurrentDomain().GetTrustRelationship() 
#Total Sites 
[system.directoryservices.activedirectory.forest]::GetCurrentForest().Sites.Count 
#All Sites Name 
[system.directoryservices.activedirectory.forest]::GetCurrentForest().Sites.name 
#DCs 
[system.directoryservices.activedirectory.domain]::GetCurrentDomain().DomainControllers 
#Nos. of DCs 
[system.directoryservices.activedirectory.domain]::GetCurrentDomain().DomainControllers.Count 
#DomainNames   
#DomainNames & Domain functional level    
#RootDomain   
#ChildDomain   
#"[ordered]" attribute is required Powershell Version 3 or above. 
$ary = [ordered]@{} 
$Contoso = [system.directoryservices.activedirectory.Forest]::GetCurrentForest().Domains 
foreach ($Domains in $Contoso) 
{ 
$ary.DomainNames = $Domains.name 
$ary.ChildDomain = $Domains.Children 
$ary.ROOTDomain = $Domains.Parent 
$ary.DomianFunctionalLevel = $Domains.domainmode 
New-Object PSObject -property $ary 
} 
#Pulling NTP Settings from all PDCs from Forest $Domains = [system.directoryservices.activedirectory.forest]::GetCurrentForest().Domains
$PDC=[System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain().PdcRoleOwner
Foreach ($PDC in $Domains)
{
w32tm /dumpreg /subkey:Parameters /computer:$PDC  
}


#How to find Remote domain DCs 

      PS C:\>$DCs = new-object 'System.DirectoryServices.ActiveDirectory.DirectoryContext'("domain", "contoso.com" )  
      PS C:\>[System.DirectoryServices.ActiveDirectory.DomainController]::FindAll($DCs)
  • Below Both the Scripts are written using NET Namespace
a) Get FSMOs for Single/Multi Domain-HTML Report

Completely written using .NET Namespace, you don't need any Powershell Module for running this Script.

2. We can manage our PKI

NameSpace

[System.Security.Cryptography]

Snap From ISE
**
**

Use  .NET Namespace to Find Expired Certificates
$cer = New-Object System.Security.Cryptography.X509Certificates.X509Store("My","LocalMachine")
$cer.Open("ReadOnly")
$cer.Certificates | Select-Object -Property Thumbprint,Subject,NotAfter
See MSDN-System.Security.Cryptography Namespace

3. We can manage our Windows Network

NameSpace

[System.Net.Sockets]

Snap From ISE

GWMi -List
2. How to get a Particular WMI Class which is having the word "Share"
GWMi -List | Select-String -Pattern share
3. How to get a Particular WMI Class which is having the word "LogicalDisk"
