Hello, I’m Muhammad Awais. I’ll stabilize your ADCS by auditing the current CA, hardening Enterprise CA, and aligning certificate templates for Kerberos, Computer/Wi‑Fi, and NPS/RADIUS. I’ll design a robust PKI baseline, ensure domain controllers renew the right Kerberos certs, and tighten controls to prevent drift. My plan: map existing templates and issuance policies, implement strict PKI best practices, test issuing/renewal flows in a controlled window, and validate NPS EAP‑TLS integration with clear revocation and monitoring. I’ll document changes, provide a repeatable template set, and set alerts for cert lifecycle issues. I’ll work with your team to minimize downtime and deliver a stable, secure CA that supports Kerberos, VPN, and Wi‑Fi auth reliably. What is your current AD forest/domain topology and CA hierarchy (Root vs SubCAs)?. Questions I’d like to confirm before we start: What is your current AD forest/domain topology and CA hierarchy (Root vs SubCAs)? Do you have any mandated PKI policies or compliance requirements (CRL/OCSP, key archival, smart cards)? Which certificate templates are needed for Kerberos, computer, Wi‑Fi, and NPS/RADIUS, and what version of Windows Server is in use? What is your intended renewal process and downtime window for CA changes? How do you want certificate enrollment sourced (autoenroll, GPOs, SCEP/ADES)? Are there existing issues with certificate autoenrollment or template issuance delays? If yes, specify. What are your monitoring/lo

Gemini said Objective: Stabilize, configure, and harden existing ADCS infrastructure. Resolve authentication failures and secure Certificate Template deployment. Unstable Active Directory Certificate Authorities present critical security vulnerabilities, specifically for Kerberos and NPS/RADIUS integrations. Execution requires isolating PKI hierarchy failure points with zero disruption to active network services. Execution Protocol: Infrastructure Audit: Analyze current Enterprise CA configuration. Verify CRL (Certificate Revocation List) distribution points and AIA (Authority Information Access) extensions are highly available and correctly published. Template Diagnostics: Audit existing Certificate Templates. Target Kerberos Authentication, Computer/Wi-Fi, and NPS/RADIUS templates. Verify Subject Name generation, Application Policies, and security permissions. Remediation & Hardening: Correct PKI hierarchy misconfigurations. Deploy industry-standard hardening protocols to the Enterprise CA to establish operational stability. Validation: Execute controlled testing of certificate enrollment and auto-enrollment processes for all affected endpoints (Wi-Fi, VPN, domain machines) to confirm persistent stability. Deliverable is a fully stabilized, documented, and secure ADCS environment. Ready to review current event viewer logs and CA configuration parameters.
