Get All DCs in the Entire Forest

Getting a know a new environment for a new client and I a quickly needed information about all domain controllers in the entire forest. Wrote a small little script to provide me all the information I needed:

Import-Module ActiveDirectory

function Get-AllDCsInForest{
[CmdletBinding()]
param(
    [string]$ReferenceDomain = $env:USERDOMAIN
)
 
$ForestObj = Get-ADForest -Server $ReferenceDomain
foreach($Domain in $ForestObj.Domains) {
    Get-ADDomainController -Filter * -Server $Domain | select Domain,HostName,Site, IPv4Address, OperatingSystem, OperatingSystemVersion
     
}
 
}

Get-AllDCsInForest| Export-Csv -Path C:\Scripts\AllDcs.txt -NoTypeInformation

Convert a Dynamic IP to Static

Working on a project where on some servers the DHCP assigned addresses needs to be converted to static. Since there is always more than one…I needed to script it. Here is a quick way to do it via PowerShell.

#SwitchIPtoStatic.ps1
#Get All the adapters that are on the Server
$adapters = gwmi -cl win32_networkadapterconfiguration | ? {($_.ipaddress) -and $_.dhcpEnabled -eq 'True' }

foreach ($adapter in $adapters) {
    # Get original settings
    $ipAddress = $adapter.IPAddress
    $subnetMask = $adapter.IPSubnet
    $dnsServers = $adapter.DNSServerSearchOrder
    $defaultGateway = $adapter.DefaultIPGateway

    # Set to static and set dns and gateway:
    $adapter.EnableStatic($ipAddress,$subnetMask)
    $adapter.SetDNSServerSearchOrder($dnsServers)
    $adapter.SetGateways($defaultGateway)
}

# Get original settings

$ipAddress = $adapter.IPAddress

$subnetMask = $adapter.IPSubnet

$dnsServers = $adapter.DNSServerSearchOrder

$defaultGateway = $adapter.DefaultIPGateway

# Set to static and set dns and gateway:

$adapter.EnableStatic($ipAddress,$subnetMask)

$adapter.SetDNSServerSearchOrder($dnsServers)

$adapter.SetGateways($defaultGateway)

}

Hope this helps!

Add Alternate Email Address or Recovery Email Address for Office365 Administrator

In Office365, depending on the admin role of an account you may want to add an alternate email address for password recovery. This is a basically a self-service password reset for Administrators of Office365. Quick way to do this is with PowerShell:

#Connect to Office365
Import-Module MSOnline
Connect-MsolService
$O365Cred = Get-Credential
$O365Session = New-PSSession –ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $O365Cred -Authentication Basic -AllowRedirection
Import-PSSession $O365Session

#Check if the user has an Alternate Email Address (Recovery Address)
Get-MsolUser -UserPrincipalName mwasay@domain.com | select -ExpandProperty AlternateEmailaddresses

#Check if the user has an Alternate Email Address (Recovery Address)
Set-MsolUser -UserPrincipalName mwasay@domain.com -AlternateEmailAddresses mwasay@domain2.com

Find Out Dns Server Addresses

The resolver is a set of routines in the C library that provide access to the Internet Domain Name System (DNS). The resolver configuration file contains information that is read by the resolver routines the first time they are invoked by a process.

$ cat /etc/resolv.conf

1	$ cat /etc/resolv.conf

OR

$ less /etc/resolv.conf

1	$ less /etc/resolv.conf

Sample output:

nameserver 203.54.1.20
nameserver 203.54.1.21

1 2	nameserver 203.54.1.20 nameserver 203.54.1.21
