function Invoke-PasswordRoll
{
<#
.SYNOPSIS

This script can be used to set the local account passwords on remote machines to random passwords. The username/password/server combination will be saved in a CSV file.
The account passwords stored in the CSV file can be encrypted using a password of the administrators choosing to ensure clear-text account passwords aren't written to disk.
The encrypted passwords can be decrypted using another function in this file: ConvertTo-CleartextPassword


Function: Invoke-PasswordRoll
Author: Microsoft
Version: 1.0

.DESCRIPTION

This script can be used to set the local account passwords on remote machines to random passwords. The username/password/server combination will be saved in a CSV file.
The account passwords stored in the CSV file can be encrypted using a password of the administrators choosing to ensure clear-text account passwords aren't written to disk.
The encrypted passwords can be decrypted using another function in this file: ConvertTo-CleartextPassword

.PARAMETER ComputerName

An array of computers to run the script against using PowerShell remoting.

.PARAMETER LocalAccounts

An array of local accounts whose password should be changed.

.PARAMETER TsvFileName

The file to output the username/password/server combinations to.

.PARAMETER EncryptionKey

A password to encrypt the TSV file with. Uses AES encryption. Only the passwords stored in the TSV file will be encrypted, the username and servername will be clear-text.

.PARAMETER PasswordLength

The length of the passwords which will be randomly generated for local accounts.

.PARAMETER NoEncryption

Do not encrypt the account passwords stored in the TSV file. This will result in clear-text passwords being written to disk.

.EXAMPLE

. .\Invoke-PasswordRoll.ps1 #Loads the functions in this script file
Invoke-PasswordRoll -ComputerName (Get-Content computerlist.txt) -LocalAccounts @("administrator","CustomLocalAdmin") -TsvFileName "LocalAdminCredentials.tsv" -EncryptionKey "Password1"

Connects to all the computers stored in the file "computerlist.txt". If the local account "administrator" and/or "CustomLocalAdmin" are present on the system, their password is changed
to a randomly generated password of length 20 (the default). The username/password/server combinations are stored in LocalAdminCredentials.tsv, and the account passwords are AES encrypted using the password "Password1".

.EXAMPLE

. .\Invoke-PasswordRoll.ps1 #Loads the functions in this script file
Invoke-PasswordRoll -ComputerName (Get-Content computerlist.txt) -LocalAccounts @("administrator") -TsvFileName "LocalAdminCredentials.tsv" -NoEncryption -PasswordLength 40

Connects to all the computers stored in the file "computerlist.txt". If the local account "administrator" is present on the system, its password is changed to a random generated
password of length 40. The username/password/server combinations are stored in LocalAdminCredentials.tsv unencrypted.

.NOTES
Requirements:
-PowerShellv2 or above must be installed
-PowerShell remoting must be enabled on all systems the script will be run against

Script behavior:
-If a local account is present on the system, but not specified in the LocalAccounts parameter, the script will write a warning to the screen to alert you to the presence of this local account. The script will continue running when this happens.
-If a local account is specified in the LocalAccounts parameter, but the account does not exist on the computer, nothing will happen (an account will NOT be created).
-The function ConvertTo-CleartextPassword, contained in this file, can be used to decrypt passwords that are stored encrypted in the TSV file.
-If a server specified in ComputerName cannot be connected to, PowerShell will output an error message.
-Microsoft advises companies to regularly roll all local and domain account passwords.

Aptikti CPassword nuostatos

Šis scenarijus turi būti vykdomas iš vietos kataloge domeno valdiklio, kurį norite išvalyti. Nukopijuokite ir išsaugoti turinį į naują "Windows PowerShell" failą, nustatyti jūsų sistemos diske ir paleiskite scenarijų, kaip nurodyta šioje naudojimo.

<#.SYNOPSIS
Group Policy objects in your domain can have preferences that store passwords for different tasks, such as the following:
1. Data Sources
2. Drive Maps
3. Local Users
4. Scheduled Tasks (both XP and up-level)
5. Services
These passwords are stored in SYSVOL as part of GP preferences and are not secure because of weak encryption (32-byte AES).
Therefore, we recommend that you not deploy such preferences in your domain environment and remove any such existing
preferences. This script is to help administrator find GP Preferences in their domain's SYSVOL that contains passwords.

.DESCRIPTION
This script should be run on a DC or a client computer that is installed with RSAT to print all the preferences that contain
password with information such as GPO, Preference Name, GPEdit path under which this preference is defined.
After you have a list of affected preferences, these preferences can be removed by using the editor in the Group Policy Management Console.

.SYNTAX
Get-SettingsWithCPassword.ps1 [-Path <String>]
.EXAMPLE
Get-SettingsWithCPassword.ps1 -Path %WinDir%\SYSVOL\domain
Get-SettingsWithCPassword.ps1 -Path <GPO Backup Folder Path>

.NOTES
If Group Policy PS module is not found the output will contain GPO GUIDs instead of GPO names. You can either run
this script on a domain controller or rerun the script on the client after you have installed RSAT and
enabled the Group Policy module.
Or, you can use GPO GUIDs to obtain GPO names by using the Get-GPO cmdlet.

Pašalinti CPassword nuostatos

Norint pašalinti nuostatas, kuriuose yra CPassword, mes rekomenduojame naudoti grupės strategijos valdymo konsolę (GPMC) domeno valdiklyje arba iš kliento, kuriame yra įdiegti nuotolinio serverio administravimo įrankiai. Jūs galite pašalinti visus nuostatų penkis veiksmus šios konsolės. Norėdami tai padaryti, atlikite šiuos veiksmus:

1. GPMC, atidarykite nuostatų, kuriame yra CPassword duomenų.

2. Pakeiskite veiksmo panaikinti arba išjungti, atsižvelgdami į nuostatų.

3. Spustelėkite gerai Norėdami įrašyti keitimus.

4. Palaukite, kol vieną ar dvi grupės strategijos atnaujinimo ciklai leisti keisti platinti klientams.

5. Po to, kai pakeitimai bus taikomi visiems klientams, panaikinkite pirmenybė.

6. Pakartokite veiksmus nuo 1 iki 5, kiek reikia išvalyti visą savo aplinką. Kai aptikimo scenarijus pateikia nulis rezultatų, darbas baigtas.
