AD Domain Services Replication, Sites & Domain Controllers

Site replication tuning and SRV record importance

October 3, 2025

Site Replication Tuning and SRV Record Importance: Why It Matters Active Directory (AD) relies on two critical mechanics to function smoothly across distributed environments: site replication tuning and SRV (Service) record management. Replication ensures domain controllers share consistent data, while SRV records in DNS help clients and…

Global catalog placement for large enterprise sites

October 3, 2025

Global Catalog Placement for Large Enterprise Sites The Global Catalog (GC) in Active Directory (AD) is more than a simple directory service role. It is the index that lets users, applications, and domain controllers (DCs) quickly find what they need across an entire forest. If you need a refresher on what a GC is and how it behaves, see Global Catalog…

AD partition audit coverage: Domain, Configuration, Schema

October 3, 2025

AD Partition Audit Coverage: Domain, Configuration, Schema – The Foundational Guide Active Directory (AD) is built on directory partitions—logical containers that scope replication, management, and security. The three most critical partitions are Domain, Configuration, and Schema. Auditing these partitions matters because each one holds…

Delegation wizard: common use cases and pitfalls

October 3, 2025

Delegation wizard: common use cases and pitfalls The Delegation of Control Wizard in Active Directory Users and Computers (ADUC) looks deceptively simple: pick an OU, pick a group, tick a few boxes, and suddenly the helpdesk can do their jobs without Domain Admin. In real environments, though, delegation is where small mistakes turn into big…

How to detect privileged group membership changes

October 3, 2025

Detecting privileged group membership changes Privileged group membership is one of the highest-leverage control points in Active Directory. If an attacker can add an account (or a computer, service principal, or nested group) to a privileged group, they often don’t need a “loud” exploit anymore—access becomes legitimate by definition.

Understanding group nesting limits and token size

October 3, 2025

Understanding group nesting limits and token size Group nesting is one of Active Directory’s most powerful features: you can model roles and access using a few reusable groups, then compose them into higher-level “business” groups. The trap is that you’re not just building a tidy hierarchy—you’re also building a logon authorization…

How to sync AD groups to cloud services securely

October 3, 2025

How to sync AD groups to cloud services securely Syncing Active Directory (AD) groups to cloud services sounds simple: “make the same groups appear in the cloud.” In practice, it’s one of the easiest ways to accidentally leak access, expand blast radius, or create hard-to-audit privilege paths across environments. This guide walks through the…

Recovering deleted groups from Recycle Bin

October 3, 2025

Recovering deleted groups from Recycle Bin Deleting the wrong group in Active Directory is one of those mistakes that feels small until everything attached to it (file shares, application roles, GPO filtering, nested memberships, Azure AD sync) starts failing. The good news: if the Active Directory Recycle Bin is enabled, a deleted group is…

Maintaining OU consistency in hybrid environments

October 3, 2025

Hybrid identity is supposed to feel like one system: the same users, the same groups, the same access decisions—just stretched acrosson-premises Active Directory and cloud identity. The reality is that the boundary between directories introduces drift: objects end up in the “wrong” OU, policy and delegation assumptions break, sync scope becomes messy, and teams start papering over it with…

Automated topology design for multi-site replication

October 3, 2025

Multi-site replication fails in two ways: either it is left to “defaults forever” and slowly drifts away from reality, or it is over-engineered into a brittle, hand-tuned maze that only one person understands. Automated topology design is the middle path: you let Active Directory generate the connection objects, but you automate the inputs (sites, subnets, site links, costs, schedules, and…
