Knowledge Base

Latest technical articles

Practical, verifiable troubleshooting sequences for common enterprise IT failures. All example environments are anonymised.

Active Directory and Group Policy

Domain join says “domain not found” or “cannot contact a domain controller”: what should you check?

Troubleshoot domain-join discovery failures in a controlled order: internal DNS, SRV records, required connectivity, time synchronisation, computer objects, and the NetSetup log.

Active Directory and Group Policy

Why must a computer use Active Directory DNS before joining the domain instead of a public DNS service?

Active Directory relies on internal DNS and SRV records to locate domain services. This article explains client DNS settings, forwarders, secondary DNS, and safe public-name resolution.

Active Directory and Group Policy

How to safely repair “The trust relationship between this workstation and the primary domain failed”

A workstation trust failure usually means the local machine-account secret no longer matches Active Directory. Confirm local access, profiles, and the secure channel before resetting or rejoining.

Windows Server and file permissions

A Windows share allows folder creation but not file creation or saving: which permission is missing?

This symptom usually comes from mismatched advanced NTFS rights and inheritance scope. Compare file creation, write data, folder creation, deletion, and ownership permissions.

Windows Server and file permissions

Share permissions vs NTFS permissions: why can access still be denied after permission is granted?

Network file access is constrained by both share and NTFS permissions, plus group membership, deny entries, inheritance, and cached credentials. Use this sequence to calculate effective access.

Active Directory and Group Policy

The same Group Policy applies to some computers but not others: a complete troubleshooting sequence

When a GPO applies inconsistently, compare OUs, policy versions, security and WMI filters, DNS, SYSVOL, client results, and events instead of relying on gpupdate alone.
