Using GPO to enforce firewall rules in Windows

March 18, 2026
Using GPO to enforce firewall rules means you stop treating Windows Firewall as a per-machine setting and start treating it as centrally managed policy.

March 18, 2026
Active Directory’s normal user property pages are fine for routine administration, but they hide an important reality: many account states are driven by raw LDAP attributes under the surface.

How to find contacts & manager relationships with PowerShell

March 18, 2026
When admins say “get the manager,” “find contacts in AD,” or “list group members,” they often sound like simple one-liners. In Active Directory, they are related tasks, but they do not all operate on the same object type or the same attribute model. That is why quick scripts often work for one case and then fail when you reuse them for another. The manager attribute is a…
