June 11, 2021September 17, 2022

In a large enterprise an admin would need to keep track of all the domains in a AD forest, the domain names, the domain controllers (DC) , their IPs, and what FSMO roles does a DC hold. Wrote a little script to just do that…

Get All DCs in the Entire Forest

March 6, 2019

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

Connecting to a remote domain controller using PowerShell

April 25, 2017April 15, 2020

Covering one of the basic day to day task if you are a Windows Administrator; connecting to the domain controller. Â I try to minimize logging onto servers as much as possible.

â€œHost SMBus controller not enabled!â€

May 20, 2016August 22, 2016

CentOSÂ guest instances in VMware sometimes come up with the boot error message:

piix4_smbus 0000:00:007.3: Host SMBus controller not enabled!

1	piix4_smbus 0000:00:007.3: Host SMBus controller not enabled!

This error is being caused because VMware doesnâ€™t actually provide that level interface for CPU access, but Ubuntu try to load the kernel module anyway. How to fix it:

sudo nano /etc/modprobe.d/blacklist.conf

1	sudo nano /etc/modprobe.d/blacklist.conf

add the line:

blacklist i2c-piix4

1	blacklist i2c-piix4

Reboot. NOTE: for older versions use blacklist i2c_piix4…
