Endpoint Management
Improve device deployment, configuration, inventory, and support across Apple and Windows fleets — plus lifecycle tracking that makes daily IT easier to trust and easier to explain.
McKinney, Texas — Healthcare, Telemedicine & SMB IT
IT leadership for teams that need
systems to hold up.
Legacy IT Consulting brings order to endpoint management, Microsoft 365 and Intune, Apple device management, disaster recovery, and everyday IT operations. Each light behind these words is one of the 1,500+ telemedicine devices Don Lamb keeps online — scroll, and watch entropy become order.
Telemetry
Cleaner systems. Clearer decisions. Fewer loose ends.
The work starts with the operational problems your team feels every week: devices that are hard to track, Microsoft 365 workflows that drift, recovery plans that were never documented, and IT decisions that need senior-level judgment.

The practice
IT services built for reliable operations
Fewer vague recommendations, more practical next steps — across devices, accounts, vendors, recovery planning, and everyday support operations.
Core services
Disaster Recovery Planning
Practical recovery plans, backup workflow review, critical-system prioritization, and runbooks your team can actually use under pressure — reviewed, tested, and improved over time.
Fractional IT Leadership
Senior guidance for vendor management, project prioritization, roadmap planning, and technology decisions — without adding a full-time executive role. Decisions leave someone's head and land on paper.
Specialized support
Jamf Consulting
Clean up Apple Business Manager alignment, Automated Device Enrollment, Jamf Pro policies, smart groups, inventory, and documentation — so Apple device management is predictable, auditable, and easy to hand off.
Microsoft 365 & Intune
Intune device policy review, Microsoft 365 administration workflows, endpoint compliance basics, security baseline cleanup, and user-and-device lifecycle processes — without the guesswork.
Healthcare IT Consulting
Endpoint and account workflows for clinics, practices, and telemedicine teams — reliability, access clarity, vendor coordination, and support workflows that protect patient-facing operations.
How engagements work
A simple path from unclear to operational
Built for practical momentum — the four stages every engagement moves through, in order.
Stage 01
Assess
Review the current environment, tools, documentation, risks, and the operational pain showing up in daily work.
Stage 02
Prioritize
Separate urgent fixes from nice-to-have work, so effort goes toward the items that reduce friction and risk fastest.
Stage 03
Execute
Clean up workflows, improve documentation, coordinate vendors, and move the environment toward a stable operating model.
Stage 04
Guide
Give leadership clear next steps, practical reporting, and a roadmap that can be maintained after the initial work is done.
Watch the sky
The fleet just split into two rings. That's a failover.
Behind this panel, the constellation has reorganized into primary and recovery sites — the same geometry Don has executed 100+ times with Zerto and Veeam, moving thousands of virtual machines for SEC-compliance testing. A recovery plan is only real once you've watched it run.

Fit
Best when IT has outgrown guesswork
Best for teams that need clarity more than buzzwords.
Healthcare & telemedicine
Teams that need endpoint reliability, access clarity, vendor coordination, and IT workflows that support patient-facing operations.
Growing SMBs
Organizations that have outgrown informal IT habits and need cleaner documentation, device management, and leadership guidance.
Apple-heavy environments
Teams using Jamf, Apple Business Manager, Automated Device Enrollment, or mixed Apple-and-Windows device fleets.
Teams between stages
Businesses that need senior IT direction before they're ready to hire a full-time IT director or CIO.
The operator
Practical IT leadership, without the corporate fog
The first computer Don built was for playing video games. It became his family's first internet connection — and the start of a fifteen-year climb from Tier I helpdesk to director-level leadership, with no degree and no shortcuts.
Along the way: training programs at Bank of America, patch management at Freddie Mac, disaster recovery engineering at Abacus Group, and building the 24/7 clinical support backbone at a national telemedicine provider — a fleet of 1,500+ devices where downtime isn't an inconvenience, it's a patient not seen.
Legacy IT Consulting supports organizations with real systems to manage, real staff depending on them, and too many IT decisions living in someone's head. The work is direct: clean up the environment, document what matters, improve the workflows, and give leadership a clearer path forward.

Common questions
Asked before you ask
Is this the same as managed IT support?
No. Managed IT usually focuses on ongoing support tickets and monitoring. This practice focuses on direction, accountability, planning, and practical operational improvement — the senior judgment layer, not the ticket queue.
Can you help without replacing our current IT provider?
Yes. Legacy IT can provide project support, operational cleanup, documentation, leadership guidance, or targeted consulting alongside your existing internal or external IT resources.
When should a business consider a fractional IT leader?
When technology decisions, vendors, documentation, and operations need senior guidance — but a full-time IT executive isn't yet practical. That in-between stage is exactly what this practice is built for.
Is disaster recovery only for large companies?
No. Small and midsize teams often need recovery planning most, because a single outage can interrupt operations quickly and expose gaps in documentation or ownership.
Can Intune replace every endpoint tool?
Not always. Intune is strong for many Microsoft-centered environments, but the right approach depends on your device mix, compliance needs, Apple management requirements, and support workflows.
