Diagnosis and resolution
Active Directory incident resolution
We help your team investigate and resolve Active Directory On-Premises failures, from symptoms and operational impact to validation of corrective actions.
We first review impact, access and environment health. Scope and availability are agreed before intervention.
Areas of intervention
- Authentication, Kerberos and sign-in errors
- Computer secure channels and domain access
- Active Directory replication and site topology
- AD-integrated DNS and domain controller discovery
- SYSVOL replication and Group Policy processing
- Domain controller services, events and connectivity
- Incidents following configuration changes
- Root cause analysis where evidence supports it
Deliverables
- Technical diagnosis and available evidence
- Record of agreed corrective actions
- Service validation and follow-up checks
- Findings and recommendations to prevent recurrence
