SysAdminTools Desktop
A free Windows companion app that runs the tools a browser can't โ local disks, network devices, NTFS permissions, Active Directory, and event logs.

SysAdminTools Desktop
v1.5.0FreeA native Windows toolkit for the tasks that can't run in a browser. It installs as a lightweight Windows service and opens a fast local web UI โ use it on the machine itself or across the LAN. Self-contained: no separate .NET install required.
What's inside
Machine dashboard
OS, hardware, memory and per-disk usage of the host at a glance.
Storage scan
Fast folder-size tree for local disks and UNC network shares โ tree, treemap, top files/folders, diff, and export.
Network scanner + map
Ping-sweep a CIDR, resolve hostnames/MAC/vendor, port-scan, classify each device, and draw a logical network map.
LAN speed test
Measure throughput to another machine โ over an SMB share or a direct peer connection.
Permissions reporter
Audit NTFS owners and ACLs; flag broken inheritance, broad 'Everyone' grants, and orphaned SIDs.
AD reporter
Privileged group members, inactive users, locked accounts, password expiry, stale computers and more (domain-joined machines).
Event log analyzer
Scan the Application/System/Security logs and surface ranked, explained problems โ bugchecks, disk errors, service crashes, failed sign-ins.
How it works
- Installs a Windows service that hosts the UI locally (default
http://localhost:5280/), plus a tray icon to open it. - Two modes, auto-detected: Client (storage & network tools) and Domain (adds AD, permissions and multi-server tools) on domain-joined machines.
- Everything runs on your machine โ no data leaves your network. Export any report to CSV.
