Active Directory, DNS and DHCP
Health checks, cleanup of old domains, domain controller replacement without readdressing, Group Policy audits, and DHCP stability work.
Infrastructure
The infrastructure under everything else
Cloud projects stall when the foundation is shaky. I fix and modernize the systems small IT teams inherit: directories, mail, servers and the network between sites.
What I work on
Directories, mail, servers and networks
Exchange and mail flow
On-premises Exchange recovery, hybrid mail-flow fixes, connector cleanup, decommissioning legacy servers, and migrations to Exchange Online.
Windows Server and virtualization
Server upgrades and migrations, Hyper-V and VMware environments, and storage planning, with a rollback plan for every cutover.
Networks across sites
Palo Alto firewalls, Aruba and Cisco switching and wireless, segmentation, and as-built documentation your team can maintain.
How a project runs
From assessment to handoff
Assessment
What's there, what's fragile, what it will take.
Written scope
A written scope and estimate before work starts.
Build and cutover
Scheduled around your school day or business hours.
Handoff
Runbooks and as-built documentation at handoff.
