tombstone lifetime default
1 Answer 1. Each Version of Windows Server since Windows 2000 implements the tombstoneLifetime attribute in Active Directory with a default value of either 60 or 180 days. What does default imply? The tombstoneLifetime attribute is set in the Configuration NC, and as such is a forest-wide setting. The version of the first Domain Controller in your forest determines the value of the tombstoneLifetime throughout the forest.
