Specialization

Directory Services, from operations to evolution

We focus on Active Directory On-Premises: understanding dependencies, resolving problems and preparing a sustainable evolution of your infrastructure.

Core Active Directory & Directory Services

AD operations

  • Domain controllers
  • Replication, DNS & SYSVOL
  • Sites, subnets & services
  • Directory Services health

Troubleshooting

  • Authentication & access
  • Replication failures
  • Group Policy processing
  • Root cause analysis

DC migration

  • Windows Server versions
  • Schema & functional levels
  • FSMO roles & DNS
  • Validation & DC retirement

Modernization

  • New AD DS capabilities
  • Application compatibility
  • Authentication security
  • Phased adoption

Your environment

When Active Directory fails, the business feels it

Access, applications and operations depend on a healthy directory.

An authentication failure, interrupted replication or a Group Policy that does not apply can affect multiple teams. Renewing domain controllers also requires an understanding of directory health and business dependencies.

  • Sign-in errors
  • Interrupted DC replication
  • DNS and DC discovery issues
  • Inconsistent SYSVOL or GPOs
  • Failing domain controllers
  • Windows Server versions due for renewal
  • Applications that depend on AD
  • New capabilities awaiting evaluation

FAQ

Before we work on your Active Directory

Which incidents can you investigate?

Authentication, replication, DNS, SYSVOL, Group Policy and domain controller service failures. We review symptoms and context to confirm scope.

Do you offer immediate response or 24/7 support?

Availability, scope and response times are agreed for each request. The form starts a conversation and does not confirm immediate intervention.

How do you migrate domain controllers?

We review directory health and dependencies, define the target version and plan new DC deployment, validation and retirement of existing controllers.

Does migration guarantee there will be no disruption?

We plan to reduce impact, but change windows, risks and contingency measures are agreed around your environment and applications.

Does migration automatically enable every new AD feature?

No. Each capability has its own requirements. We review versions, functional levels and compatibility before proposing activation.

Do you also provide assessments and hardening?

Yes. Assessments, hardening and ongoing reviews complement incident resolution and Active Directory evolution.

What information do you need to start?

A description of the problem or project, Windows Server versions and approximate user and DC counts. We coordinate evidence sharing afterwards; do not include passwords in the form.
