Legacy Systems & OS Modernisation

From Windows NT 4.0 to Server 2025: Two Decades of Expertise

Technology moves fast, but critical business assets often move slower. At Kent-ITS, we have been managing Windows environments since 2003. We don't just understand the latest cloud builds; we have "boots on the ground" experience with the legacy systems that still power niche industrial and financial applications today.

The Full Spectrum of Windows Evolution

We have supported every major milestone in Microsoft’s history. This isn't just trivia—it's the ability to troubleshoot the root cause of a problem that a modern technician wouldn't even recognize.

  • The Legacy Era (NT 4.0 & Windows 98): We understand the architecture of NT 4.0 (Workstation & Server) and the "Service Pack" saga that defined it. Whether it's a legacy CNC controller on Windows 98 or an old proprietary database on NT, we know how to keep these systems alive, isolated, and functional.

  • The Server Revolution (2000 – 2012 R2): We lived through the birth of Active Directory in Windows 2000 and the legendary stability of Server 2003. If you have a business system that refuses to run on anything newer than 2012 R2, we have the virtualization and legacy-support skills to maintain it.

  • The Modern Standard (Server 2019 – 2025): We are already deploying Windows Server 2025, utilizing its advanced SMB over QUIC features and Hotpatching capabilities to provide our clients with the most secure, high-performance infrastructure available.


Managing the 'Un-Upgradable'

Sometimes, you cannot simply "upgrade." A £50,000 piece of machinery might require a specific ISA card or a driver that only exists for Windows XP.

  • Virtualization (P2V): We can "lift and shift" your physical legacy servers into a virtual environment. This allows 30-year-old software to run on modern, redundant hardware with LTO backups, removing the risk of ancient motherboard failure.

  • Hardened Isolation: Legacy systems (NT4/98/XP) are a security risk if left on a standard network. We use VLAN Segmentation and "Jump Box" architectures to ensure your legacy machines can work without ever being exposed to the internet or your main office network.

  • Legacy Interoperability: We specialize in making the "Old talk to the New." Whether it's mapping a Samba share to an NT 4.0 box or ensuring Active Directory backward compatibility, we bridge the generational gap.


Why Legacy Experience Matters

Most modern IT firms will tell you "it can't be done" if a system is out of support. At Kent-ITS, we look at the business value. If that legacy NT 4 box is critical to your revenue, we find a way to secure it, back it up, and keep it running—while planning a safe migration path for the future.
