Partnering with me will provide you with the seasoned expertise and broad skill set you need to resolve your DNS and Active Directory issues. Over the course of my 10+ years in the IT industry, I've honed my skills extensively in Network Administration and Server Administration - running the gamut from optimizing DNS configurations to ensuring smooth AD replication. In addition, I possess high-level certifications in both Cisco (CCNA & CCNP) and Microsoft (MCSA 2012) that speak to my ability to tackle complex networking challenges. Moreover, my experience extends beyond on-premises servers to encompass virtualized environments as well. Specifically, I have hands-on experience with VMware Virtualization and Microsoft Hyper-V deployments - knowledge which has helped me troubleshoot beyond the physical confines of hardware limitations. My understanding of these systems, coupled with my knowledge of Storage Area Networks (SAN), will be extremely beneficial when examining your infrastructure. Finally, my commitment to delivering high-quality work is unwavering. This includes providing comprehensive reports and thorough documentation so that you are informed about the steps taken to resolve the issue and how to prevent its recurrence. I believe this level of transparency is essential in troubleshooting such critical components of IT infrastructure like DNS and AD.

Initial Assessment: We gather details about the issues, their timeline, and affected users/devices. We then conduct health checks on AD and DNS servers, verifying network connectivity and service status. Server event logs are analyzed to identify any reported AD or DNS errors. Active Directory Troubleshooting: Replication: We investigate replication health between domain controllers using repadmin /replstatus and address any inconsistencies. DNS Issues: We review DNS server event logs to identify problems impacting AD functionality. Group Policy: Tools like gpresult /r on client machines are used to troubleshoot group policy application errors. DNS Troubleshooting: Record Verification: Tools like nslookup or dig verify DNS record resolution and identify discrepancies. Zone Configuration: We ensure correct configuration of DNS zones and verification of resource records pointing to appropriate resources. Forwarders: We check forwarder configuration for resolving external domain names and ensure their reachability. Server Events: DNS server event logs are analyzed for errors related to zone transfers, name resolution, or record updates. Advanced Techniques: Microsoft Tools: Microsoft-provided tools like the Active Directory Diagnostics tool and the Active Directory Replication Status Tool are utilized for in-depth problem identification. DNS Manager: The DNS Manager MMC snap-in is employed to manage DNS zones, forwarders, and resolve configuration issues.

I have extensive experience working successfully with 30 clients over the last 5 years. During each of those projects I quickly assessed their Active Directory environments, built a plan to achieve our goals then executed that plan. I would start by reviewing your DNS configuration, the DNS servers that the domain controllers are using and verify network connectivity on the appropriate network port (to ensure there are no internal firewalls blocking communication). I would estimate that I should have a solution identified by the second day and pending your approval have it implemented by no later than the third day.
