Directory Services Repair

We troubleshot replication issues across mixed-mode environments spanning Windows Server 2012 R2 through Server 2022:

• SYSVOL Replication: Repairing SYSVOL replication failures and migrating legacy FRS to DFSR to restore Group Policy distribution across domain controllers
• AD Object Recovery: Recovering accidentally deleted users, groups, and OUs using the Active Directory Recycle Bin and authoritative restores
• Replication Topology: Diagnosing and resolving inter-site and intra-site replication failures, lingering objects, and USN rollback scenarios

Hybrid Identity & Security

We bridged on-premises Active Directory with cloud identity platforms, hardening the entire identity chain against modern threats:

• Entra ID Connect Synchronization: Fixing broken Microsoft Entra ID (formerly Azure AD) Connect synchronization, resolving attribute conflicts, and ensuring seamless SSO between on-premises and Microsoft 365
• MFA Enforcement: Rolling out multi-factor authentication across organizations, resolving enrollment issues, and configuring fallback methods
• Conditional Access Policies: Designing and repairing Conditional Access policies to enforce location-based, device-based, and risk-based access controls
• Tiered Administration: Implementing Tiered Administration models to contain lateral movement and stop ransomware spread through privileged account isolation
• Compromised Environment Remediation: Auditing and repairing AD environments that had been compromised, including credential rotation, trust validation, and Kerberos ticket purging
