Virtualization of Physical Servers and High Availability System Implementation
How we virtualised a company's physical servers and moved the PDC and phone system to high availability, while containing hardware costs.

Windows Server remains the reference platform for many businesses running Windows-native management software, Active Directory domains and on-premises Exchange email infrastructures.
We design and maintain these environments — domain controllers, file servers, Exchange Server — with independent backups and planned update schedules, for infrastructures that must stay reliable for years.
On Windows Server we build the Active Directory domains that manage users, computers and network permissions across your business, with one or more domain controllers to keep the domain running even if one machine goes offline. We pair this with file servers that use granular per folder permissions, disk quotas and the recycle bin, so a file deleted by mistake does not require a full restore from backup. Where email needs to stay in house we also configure on premises Exchange Server, with its mailboxes and transport rules.
We do not install these roles on undersized hardware. We assess whether the domain controller, file server and any Exchange role should run on separate physical machines or on virtual machines, often on Proxmox, the virtualisation platform we use for most of the projects we handle. This lets us consolidate several Windows Server roles on less physical hardware, with snapshots and backups managed at the infrastructure level, not just on the individual server.
Windows Server remains the right choice for businesses running Windows native management software that needs a local domain, technical firms with shared CAD files on network folders with complex permissions, or businesses that still keep Exchange on premises for regulatory or legacy integration reasons. It is also the typical backbone for networks with multiple sites that need to share the same user identities across a single domain.
It is not the right fit when your business has no applications tied to a local domain and only needs email, files and collaboration: in that case Microsoft 365 avoids maintaining hardware, CAL licences and security updates on a physical server in the office. We assess this case by case: sometimes the sensible answer is hybrid, with a smaller local Active Directory domain and email moved to Exchange Online.
We start by reviewing the number of users, the applications tied to the domain and the layout of your sites before sizing the project. We design the Active Directory structure, organisational units, groups and group policies, then install and configure the domain controllers and file servers in our Melzo lab, where we test the environment before moving it into production at the client site.
After testing, we keep supporting the infrastructure with ongoing maintenance: planned security updates, domain controller monitoring and independent backups that we verify periodically, not just configured once and left alone. We handle both in warranty and out of warranty support on the physical hardware Windows Server runs on, with HP, Dell or Lenovo hardware also available on operational rental for the periodic refresh of your servers, without tying up capital in a direct purchase.
Backup of an Active Directory domain and a Windows file server needs to be independent from the server itself: if the domain controller fails, the backup must allow a restore onto different hardware, not just a rollback of the same disk. We plan regular copies with periodic restore tests, because a backup that has never been tested is often useless exactly when you need it most.
We also track the end of life of Windows Server versions: when a version leaves Microsoft support, we plan the upgrade before the lack of security patches becomes a real risk for the domain. We support clients who need to comply with the NIS2 directive with access controls, patch management and domain monitoring in line with the required obligations.
Yes, if your business runs Windows native management software or file servers with complex permissions to manage centrally. If you only need email and shared files, Microsoft 365 is often the simpler answer. We assess it together by looking at the applications you actually use.
It depends on the roles involved, domain controllers, file servers, any Exchange role, and whether the service needs to stay live during the migration. We review the existing environment before quoting the project, often planning the migration in waves on Proxmox.
In many cases yes: Azure Hybrid Benefit lets you reuse Windows Server licences you already own on cloud virtual machines or on machines virtualised on Proxmox, without buying new ones. We check the compatibility of your existing licences during the analysis phase.
Yes: we review the existing configuration, the structure of users and organisational units, and take over ongoing maintenance, with or without migrating the environment to new hardware or virtual machines. No unnecessary changes are made before we understand how your domain is actually used.
Without security patches the domain becomes a real risk. We plan the upgrade in advance, assessing whether it makes sense to stay on an updated Windows Server or move some roles to Microsoft 365, based on the applications that depend on the domain.
