Terminal Services Manager 26.03 - What's New

Redesigned interface, RDP connection quality monitoring, advanced filtering, and 130+ admin commands

Terminal Services Manager 26.03 is a major update. New interface, new monitoring capabilities, and a lot of new tools for day-to-day RDS administration.

Redesigned interface

The interface now supports Dark Mode (automatic, always dark, or always light), high-DPI displays with per-monitor awareness, and Windows 11.

Charts have been rewritten with a Skia-based graphics engine. You can zoom, measure, and export to clipboard or file. The legend shows min, max, average, and current values in real time.

RDP connection quality monitoring

Per-user columns show TCP RTT, TCP bandwidth, output FPS, and frame quality for every active session. A signal-strength icon shows connection quality for each session. Server-level columns show Avg TCP RTT, Avg output FPS, Avg input FPS, and Avg frame quality. A signal-strength icon on each server shows the worst connection quality.

Session diagnostics

When a user reports a slow session, seven diagnostic columns show what's going on: packet loss rate, retransmission rate, FEC correction rate, frames skipped (client/network/server), and encoding time. Filter for Loss rate > 1 or Retransmission rate > 5 to find problem sessions across your servers.

11 server performance metrics

Beyond CPU and memory: available memory, pagefile usage, disk free space, disk read/write speed, disk busy percentage, disk queue length, network bytes received and sent, and system uptime. All with real-time charts.

Advanced filtering on every tab

Multi-condition filters with AND/OR logic, text matching, numeric comparisons, and a "between" operator. Active conditions show as removable chips. Quick search highlights matches in the tree. 19 presets included for Servers, Users, and Processes tabs.

130+ administrative commands

Over 130 commands in 12 categories: Network Diagnostics, PowerShell Remote, System Monitoring, Security & Audit, Sysinternals Suite, and more. You can add your own commands and categories, and import/export sets in JSON, XML, or Plain Text.

4 new computer discovery sources

Find computers from Hyper-V, RDS Connection Broker, SCCM/MECM, and WSUS - in addition to Network, Active Directory, and IP Range.

Add multiple computers

Instead of typing each name, enter a pattern and let the program generate the list. A live preview shows all names before you add them.

Supported patterns:

• Comma list: {a,b,c} iterates over comma-delimited values. server{a,b,c} produces servera, serverb, serverc.

• Numeric range: [1-10] generates numbers from 1 to 10. Leading zeros set minimum width: [001-15] produces 001, 002, ..., 015.

• Range with step: [1-10:2] produces 1, 3, 5, 7, 9.

• Alpha range: [a-z] or [A-Z] for single characters. [aa-zz] for multi-character sequences.

Patterns can be combined.

Bulk operations for computer lists

Remove inactive or duplicate computers, normalize names, add prefixes, group by subnet or domain, and format descriptions from templates. A live preview shows what will change before you apply.

Administration tools

Terminal Services Manager includes tools for day-to-day RDS administration:

• Log off or disconnect idle users across selected servers by time threshold

• Log off disconnected users to clean up stale sessions

• Send messages to individual users or all users on a server

• Shadow (remote control) a user session

• Terminate processes running on remote servers

• Reset stuck sessions

• Manage user profiles on remote computers - view, delete, free up disk space

• User activity audit - track logon, logoff, disconnect, and reconnect events

• Failed logon monitoring - who, when, and from which address

• Configure Remote Desktop - enable or disable on remote computers

• RDS Licensing - license server info, grace period status, license pack details

• Restart or shut down servers remotely

• Export servers, users, or processes lists to CSV

Configurable idle threshold

The idle threshold is now configurable from 1 to 1440 minutes (default: 5 minutes). The previous hardcoded 60-second value made most sessions appear idle.

9 new languages

Now available in 16 languages: English, French, Spanish, Catalan, Slovenian, Brazilian Portuguese, Chinese, Dutch, German, Italian, Japanese, Korean, Polish, Russian, Ukrainian and Turkish.

System requirements: Windows 10 or later. Windows 7 and 8 are no longer supported.
