Let’s switch to the client and run gpupdate /force. #Windows server password repository update#We’ve got these two policies configured in the GPO and then we are ready to update the policy on the client level. We have also to enable LAPS under “Enable local admin password management”. >LINK to the PsExec tool>LINK to the LAPS Policies -> Administrative Templates -> LAPS we can see Password settings allowing us to configure the complexity, length of the password, and change period. In order to hop in between the workstations and servers, we can use PsExec tool: We should be ready for now and in order to jump further. Well for real, we are actually the local administrator, we’ve got a token of the local administrator but a whoami utility will not show us this. The result looks quite funny because if we run whoami in this new console that we have just opened, here we can see that we are Freddy Krueger. >LINK to the Mimikatz>LINK to the PsExec tool>LINK to the Mimikatz to specify the hash that we know. It is important to understand the problem first so that we get the solution later. #Windows server password repository how to#Then I will show you how to configure it with PowerShell, how to configure the group policy, and effectively how it works, including grabbing the hashes.īefore we learn how to implement LAPS, I would like to show you where the problem is by performing the Pass the Hash attack with our customized version of Mimikatz (an amazing tool written originally by Benjamin Delpy). #Windows server password repository install#First, we are going to install it onto the domain controller and on the endpoints. Save, close and restart powershell (or execute the profile script with iex $PROFILE).In this video tutorial, you will learn how to implement a Local Admin Password Solution (or Local Password Management) called LAPS. ::defaultwebproxy.BypassProxyOnLocal = $true ::defaultwebproxy = new-object (' ::defaultwebproxy.credentials = ::DefaultNetworkCredentials If the file doesn’t exist, Notepad will prompt you to create it.

Many applications live on the assumption that nobody uses proxy servers, thus making online repositories inaccessible for new installations and for automatic updates.
