Remote Desktop Connection Manager v2.93: A Deep Dive

Remote Desktop Connection Manager v2.93

Remote Desktop Connection Manager v2.93 Remote Desktop Connection Manager (commonly known as RDCMan) is a powerful tool originally developed by Microsoft engineer Julian Burger that helps system administrators manage multiple Remote Desktop Protocol (RDP) sessions in a consolidated, organized interface. With version 2.93, part of the Sysinternals suite, RDCMan continues to be a valuable asset for managing server farms, data centers, and remote lab environments. Microsoft Learn+2FileEagle.com+2

In this article, we examine what makes RDCMan v2.93 significant, its key features and improvements, its limitations, and guidance on how to use it effectively.

Historical Context & Evolution

RDCMan was initially released to simplify the management of many RDP connections by organizing them into groups and enabling bulk operations. TechTarget+1 However, earlier versions of RDCMan (before 2.8) had serious security vulnerabilities, which led Microsoft to remove them from download sites. webdevolutions.blob.core.windows.net+1

Later, Microsoft reintroduced RDCMan under Sysinternals, and with that reintroduction came improved security, bug fixes, and a more modern standalone binary that doesn't require a full installation. blog.invgate.com+1 Version 2.93 represents one of the newer stable releases, and is even offered via winget for easy installation or upgrade.

Core Features of RDCMan v2.93

RDCMan v2.93 retains and refines many of the hallmark features that make it popular among administrators. Here are its key capabilities:

1. Group and Hierarchy Management of Servers

  • You can organize servers into named groups (e.g., by function, geography, environment) and subgroups. Microsoft Learn+1

  • Group-level settings can propagate to all member servers (credential inheritance, common RDP parameters), saving time and reducing configuration errors. Microsoft Learn

2. Credential Management

  • RDCMan supports storing login credentials, which can be reused across groups or individual servers. TechTarget+1

  • Passwords are encrypted securely using CryptProtectData or via X.509 certificates, protecting stored credentials from unauthorized access. Warp2Search+1

  • Credential profiles allow central management: change your password once, and that update ripples through all relevant connections. Microsoft Learn

3. Visual Session Thumbnails

  • When you open a group of servers, RDCMan can display each server session as a live thumbnail — letting you monitor multiple remote desktops in real time. Warp2Search

  • This “dashboard” style view helps admins quickly identify which servers are active, idle, or experiencing issues.

4. Virtual Groups and Smart Groups

  • Smart Groups: Dynamically populated based on rules (e.g., servers that match certain names or properties) so that your group layout can adapt as servers change. Microsoft Learn

  • Connected Virtual Group: Automatically tracks which sessions are currently open. Microsoft Learn

  • Reconnect Virtual Group: You can drag servers here when they are expected to go offline (e.g. for reboot), and RDCMan will continuously attempt to reconnect. Microsoft Learn

  • Favorites & Recent Virtual Groups: These let you highlight and quickly jump to frequently used or recently accessed servers. Microsoft Learn

5. Flexible Display & Full-Screen

  • The RDP client panel can be resized, docked, or adjusted per connection. Microsoft Learn

  • Full-screen sessions are supported (using configurable hotkeys), including spanning multiple monitors if needed. Microsoft Learn

  • To prevent confusion, you can lock the RDCMan window size so the UI remains consistent. Microsoft Learn

6. Session Management

  • Through the Session menu, you can connect, disconnect, or log off multiple servers at once. Microsoft Learn

  • You can also send special key combinations like Ctrl+Alt+Del, or switch focus between sessions using keyboard shortcuts. Microsoft Learn

  • Command-line support enables automation: for example, /c server1,server2 to connect multiple servers, /reconnect to restore previous session states, etc. Microsoft Learn

7. Local Resources & Security Configuration

  • RDCMan allows redirection of local resources: drive sharing, clipboard, printers, smart cards, and more. Microsoft Learn

  • You can configure network-level authentication (NLA) and certificate-based encryption for enhanced security. TechTarget

  • Hotkeys, window behavior, and UI experience (animations, background, etc.) are fully configurable to suit your network speed or preferences. Microsoft Learn

8. Policy & File Management

  • RDCMan reads policy settings from the registry (HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\RDCMan) to enforce organizational rules. Microsoft Learn

  • Sessions and groups can be saved as .rdg files, making configuration portable and shareable. Microsoft Learn

Advantages of Version 2.93

  • Up-to-date and Maintained: As part of the Sysinternals suite, v2.93 is more current and stable than the older, deprecated versions. Microsoft Learn+1

  • No Installer Required: The tool is portable — you simply extract the ZIP and run the executable, making it easy to deploy or carry on a USB. blog.invgate.com

  • Secure Credential Storage: Encryption using local user credentials or certificates protects stored logins. FileEagle.com

  • Efficient Management: The grouping, virtual groups, and dynamic smart-groups significantly improve efficiency when managing large numbers of servers.

  • Automation Ready: With command-line options, administrators can script operations (like reconnecting or opening particular sets of servers).

Known Limitations and Criticisms

While RDCMan v2.93 is useful, it also comes with some drawbacks that users have discussed in various forums and Q&A platforms:

  1. Connection Delays

    • Some users report that RDCMan can take several minutes to establish a connection, showing “Connecting to …” for a long time. Microsoft Learn

    • This delay seems specific to the way RDCMan launches RDP sessions, and may not be present when using native mstsc.exe.

  2. Security History & Warnings

    • Despite improvements, RDCMan has a checkered past: older versions had security vulnerabilities, which made Microsoft temporarily remove it. webdevolutions.blob.core.windows.net

    • For advanced security needs (e.g. two-factor authentication, privileged access management), some organizations prefer more feature-rich tools like Remote Desktop Manager (by Devolutions) rather than RDCMan. webdevolutions.blob.core.windows.net+1

  3. Limited Modern Features

    • Compared to newer remote desktop managers, RDCMan lacks advanced features such as audit logging, integrated privileged account management, or sophisticated scripting/plugins. webdevolutions.blob.core.windows.net

    • File encryption protection is limited: while credentials are encrypted, the .rdg configuration files themselves are not fully encrypted by default. Reddit

  4. User Interface Quirks

    • Some administrators note that keyboard shortcuts (e.g., to cycle through sessions) may behave unexpectedly or inconsistently. TECHCOMMUNITY.MICROSOFT.COM

    • Thumbnail focus can cause confusion: when multiple sessions are open, keyboard focus might not always be where you expect. Microsoft Learn

  5. Deprecated in Some Contexts

    • While still used, Microsoft has recommended for some users to consider other remote desktop solutions rather than relying on RDCMan long-term. TechTarget

    • For Windows environments with strict modern security requirements, many admins view RDCMan as less suitable than more actively developed tools.

Best Practices for Using RDCMan v2.93 Effectively

If you decide to use RDCMan v2.93, here are some practical tips and best practices to maximize its benefits while minimizing risk:

  • Use on Secure Machines: Since credentials are stored (albeit encrypted), make sure RDCMan is run only on trusted and secured administrator workstations.

  • Leverage Credential Profiles: Use shared credential profiles across related server groups. This simplifies password updates and reduces duplication.

  • Set Static IPs or DNS: For ease of management, use DNS names or static IPs for servers. This makes configurations more stable across sessions.

  • Back Up .rdg Files: Regularly back up the RDCMan configuration (.rdg) files, especially before making bulk changes.

  • Customize Auto-Reconnect: For servers that frequently reboot (e.g., VMs for development/test), use the Reconnect Virtual Group to automatically re-establish sessions.

  • Monitor Performance: If connection delays are problematic, test alternative remote clients (like mstsc.exe) to compare speeds.

  • Consider Alternatives for High-Security Environments: For environments requiring modern security features (2FA, logging, privileged account control), evaluate whether a more feature-rich remote desktop manager is more appropriate.

Conclusion

Remote Desktop Connection Manager v2.93 Remote Desktop Connection Manager (RDCMan) v2.93 is a mature, lightweight, and efficient tool for managing large numbers of RDP connections. Its group-based organization, credential management, and visual thumbnail interface make it especially well-suited for system administrators working in data centers, development labs, or test environments.

While it has limitations—particularly around security features and occasional connection delays—it remains relevant thanks to its portability, simplicity, and the fact that it is actively maintained as part of the Sysinternals suite. When used with best practices, RDCMan v2.93 can streamline remote desktop workflows and significantly boost productivity.

If you’re considering using RDCMan v2.93, assess your security requirements, determine whether its feature set aligns with your needs, and make sure to follow recommended setup practices. For many administrators, it's still a go-to tool—but for others, especially in high-security or enterprise scenarios, exploring more advanced remote desktop management solutions may be the right choice.

If you like, I can also compare RDCMan v2.93 with modern alternatives (like Devolutions Remote Desktop Manager, mRemoteNG, etc.). Do you want me to do that?
