The snippet below can be used to quickly add SIP entries to the Active Directory ProxyAddresses field for full Office integration in Cisco Jabber.

Import-Module ActiveDirectory
$domainController = 'dc.contoso.com'
$searchBase = 'OU=Users,DC=contoso,DC=com'

$users = Get-ADUser -SearchBase $searchBase -SearchScope Subtree -Filter { ObjectClass -eq "user" } -Properties ProxyAddresses

ForEach ($user in $users) {
	$newSip = 'SIP:' + $user.SamAccountName + '@contoso.com'
	Write-Host "Adding $newSip to" $user.SamAccountName
	Set-ADUser -Identity $user.DistinguishedName -Add @{proxyAddresses = $newSip} -Server $domainController
}

Adding multiple subnets to AD Sites and Services, utilizing the New-ADSubnet script found on PoshCode. Quick and simple. Could easily be made to pull subnets from a CSV as well.

$subnets = @("192.168.1.0/24", "192.168.2.0/24")
foreach ($s in $subnets) { .\New-ADSubnet.ps1 $s Default-First-Site-Name USA/KY/Louisville }

Get list of users who have forwarding enabled on their accounts:

Get-Mailbox -Filter { ForwardingAddress -like "*" } | Where-Object { $_.ForwardingAddress -like "*" } | Select-Object Name,ForwardingAddress

Get list of users who have forwarding rules configured in their mailboxes:

ForEach ($m in (Get-Mailbox -ResultSize Unlimited)) { Get-InboxRule -Mailbox $m.DistinguishedName | where { $_.ForwardTo } | fl MailboxOwnerID,Name,ForwardTo }

Get list of users who have redirects configured on their mailboxes:

ForEach ($m in (Get-Mailbox -ResultSize Unlimited)) { Get-InboxRule -Mailbox $m.DistinguishedName | where {$_.ReDirectTo} | fl MailboxOwnerID,Name,RedirectTo }

Powershell command to export all user email addresses to an Excel sheet. Below uses OrganizationalUnit, you could change the Get-Mailbox criteria to Server, Database, or whatever your requirements.

Get-Mailbox -OrganizationalUnit 'contoso.com/users' -ResultSize Unlimited | Select-Object DisplayName,ServerName,PrimarySmtpAddress, @{Name=“EmailAddresses”;Expression={$_.EmailAddresses | Where-Object {$_.PrefixString -ceq 'smtp'} | ForEach-Object {$_.SmtpAddress}}} | Export-Csv -Path some-file.csv

This is caused by a either a corrupt QBDataServiceUserXX, disabled QBDataServiceUserXX, or if the password has been changed. QBDataServiceUserXX is a user that quickbooks creates to authenticate and start a service called QuickbooksDBXX. The service is responsible for managing access to the data in the company file. It can also cause multiuser issues if it is not running properly.

I got tired of running through the steps on the Intuit website so I whipped up this quick batch script. This will set a new password on the QBDataServiceUserXX account and restart the QuickBooksDBXX service.

@echo off
set newpass=%random%%random%%random%
echo Setting new password on QBDataServiceUser20...
net user QBDataServiceUser20 %newpass%
echo Setting password on service...
sc config "QuickBooksDB20" obj= ".\QBDataServiceUser20" password= "%newpass%"
echo Starting QuickBooksDB20 service...
net start QuickBooksDB20

Powershell script to determine the last time a user changed their password. Also displays domain password age, can it expire, and if the password is currently expired.

Powershell snippet for duplicating receive connectors on new servers. This goes well with my Setup Anonymous Relay on Exchange 2010 Receive Connector post.

The Pspasswd utlitiy, which comes as part of the Sysinternals PsTools kit, can be used to reset the local administrator password on machines locally or remotely. Obviously, this comes in handy when you’re not sure of the local administrator password on a domain joined machine.

Resetting the local administrator account on a single machine:

pspasswd \\server.contoso.com administrator "passwordGoesHere"

You can also specify a list of computer names in a text file to change the password on multiple machines. The example below assumes computerlist.txt contains a list of computer names, one per line:

pspasswd \\@computerlist.txt administrator "passwordGoesHere"

Quick one-liner to pull printer names, drivers, and ports, from a print server.

	$colItems = Get-WmiObject Win32_BIOS -Namespace “root\CIMV2" -computername $x.DNSHostName -ErrorAction SilentlyContinue

	if ($colItems -ne $null) {
		ForEach($objItem in $colItems) { 
			Write-Host $x.Name "=" $objItem.SerialNumber
