Dutch Data Protection Authority @toezicht_AP measured the number of data theft reports in 2020 and it skyrocketed. It increased 30% in 2020 compared to 2019. Less data breach reporting, more hacking, malware & phishing. #GDPR #Privacy #DataBreach Use #MFA https://t.co/owmjDbwMgO https://t.co/tHQS5XzEf0

@WebHallaHow to determine Active Directory Tombstone Lifetime
Microsoft Active Directory is a multi-master database replicated among multiple Domain Controllers. To make sure that objects are fully replicated before any deletions are processed (purged), objects are marked for deletion (soft delete).The Active Directory Tombstone Lifetime determines how long deleted items exist in the Active Directory before they are purged. The default value was originally 60 days, but this was increased to 180 days starting with new Active Directory forests created with Windows 2003 SP1 or newer. This also has consequences for Domain Controllers down time. A Domain Controller that is off-line for longer than the Active Directory Tombstone Lifetime should not be brought on-line.
How to determine Active Directory Tombstone Lifetime value?
This topic will show you two ways:- Using AdsiEdit
- Using PowerShell 2.0 or newer
Determining Active Directory Tombstone Lifetime value using AdsiEdit
- Start AdsiEdit
- Navigate to Configuration [<FQDN server>] | CN=Services | CN=Windows NT | CN=Directory Service
Example: CN=Configuration,DC=NLAALDC1,DC=local | CN=Services | CN=Windows NT | CN=Directory Service - Right click and select Properties
- Select tombstoneLifetime
- When the value is not set, the tombstone lifetime setting is set to 60 days (default for AD forests installed with Windows 2003 or older).

- by default, on a Windows Server 2008 R2, 2012 R2 or newer when you install the AD DS or AD LDS server roles
- by default, when you make a Windows Server 2008 R2 or newer a domain controller by running Dcpromo.exe
- as part of the Remote Server Administration Tools (RSAT) feature on a Windows Server 2008 R2 server
- as part of the RSAT feature on a Windows 7, 8.1 or 10 computer
Using this script on a Windows 7, 8.1 or 10 desktop?
You may need to load the Active Directory module by configuring RSAT. Read more about installing and configuring RSAT here
