The file PSMInitSession.exe is a critical component of the CyberArk Privileged Session Manager (PSM). It is the initial program responsible for launching and managing the user session once a connection is established.
Below is a structured "paper" summarizing its role, common issues, and troubleshooting steps. Overview of PSMInitSession.exe
Role: It serves as the primary session initiator. When a user connects via PSM, the server establishes a Remote Desktop (RDP) session and automatically executes this program to start the privileged session flow.
Default Location: Typically found at C:\Program Files (x86)\CyberArk\PSM\Components\PSMInitSession.exe.
Function: It acts as a wrapper that ensures the correct environment is loaded, security policies (like AppLocker) are active, and the session is ready for the end user. Common Error: "Initial program cannot be started"
This is the most frequent issue encountered with this executable. It typically stems from the PSM server's inability to launch the process during the session handshake. Primary Causes and Solutions PSMSC036E No Process was found for image - CyberArk
PSMInitSession.exe is a critical application within the CyberArk Privileged Session Manager (PSM)
environment. It serves as the bridge between the initial user login to the PSM and the final connection to the target asset. Core Functionality
The primary role of PSMInitSession.exe is to facilitate the secondary connection in a secure session: Session Initiation : Once a user (via accounts like PSMConnect PSMAdminConnect
) logs into the PSM server, this application automatically triggers. Credential Retrieval : It takes the connection information provided by the Privileged Vault Web Access (PVWA) and retrieves the necessary target credentials from the CyberArk Vault to establish the connection to the end machine. RemoteApp Wrapper : It is typically published as a
on the PSM server, ensuring users see only the target application rather than a full desktop environment. CyberArk Docs Configuration & Lockdown Features
Because this executable is the entry point for privileged sessions, it is central to the "hardening" of a PSM server: Auto-Logon Program : In typical setups, it is configured in the Environment tab of the PSMConnect
user's properties to "Start the following program at logon". Security Lockdown (AppLocker) : Administrators use to deny all executable rules on the PSM server
for PSMInitSession.exe. This prevents users from bypassing session monitoring or running unauthorized programs once they have an active RDP session. Monitoring
: It supports live monitoring by allowing other authorized users to view or interact with the session through its Remote Control features. CyberArk Docs Common Implementation Steps : By default, it is found in
C:\Program Files (x86)\CyberArk\PSM\Components\PSMInitSession.exe Publishing
: For the best user experience, it should be published as a RemoteApp within Server Manager under Remote Desktop Services Collections. troubleshooting steps psminitsessionexe
PSMInitSession.exe is a core component of the CyberArk Privileged Session Manager (PSM)
. It acts as the "initial program" that triggers when a user initiates a privileged session through the PSM. Core Functionality Session Initiation : Similar to how userinit.exe works for Windows logins, PSMInitSession.exe first application to run
when the PSMConnect or PSMAdminConnect users log into the PSM server. Bridge to Target : It retrieves connection information from the Privileged Vault Web Access (PVWA)
and establishes the second leg of the connection to the final target machine.
: It ensures that the user session is restricted to the specific administrative tool or application requested, rather than providing a full desktop environment. Common Issues & Troubleshooting If you encounter errors like "This initial program cannot be started"
"PSMSC036E No Process was found for image [PSMInitSession.exe]" , check the following: User Environment Permissions : Ensure the PSMConnect user profile is correctly configured to launch the program at logon . The default path is typically
C:\Program Files (x86)\CyberArk\PSM\Components\PSMInitSession.exe AppLocker Rules
: PSM hardening often uses AppLocker. If the rules are misconfigured (especially for domain users), they may block PSMInitSession.exe from executing.
: Slow session startups can trigger errors. You may need to increase the InitSessionTimeout PVWA Session Settings from the default 15 seconds. Registry Bloat : On older Windows Server versions, registry bloating VolatileNotifications
keys can prevent new sessions from starting until the server is rebooted. Verification Method
This report covers PSMInitSession.exe , a critical component of the CyberArk Privileged Session Manager (PSM) responsible for initializing the RDP session environment when a user connects through the PSM. 1. Executive Summary PSMInitSession.exe
is the "Initial Program" launched by the Remote Desktop Protocol (RDP) when the PSMConnect
user logs into a PSM server. Its primary role is to bridge the gap between the initial login and the actual target application (e.g., a SSH client, web browser, or management console). If this executable fails to run, the entire privileged session will fail to start, often resulting in an error message stating: "This initial program cannot be started" 2. Core Functionality Startup Trigger: It is configured as the startup program for the PSMConnect (and sometimes PSMAdminConnect ) user accounts. Session Handover:
It manages the transition from the PSM server login to the execution of the specific connection component required for the target system. Typically found in the default path:
C:\Program Files (x86)\CyberArk\PSM\Components\PSMInitSession.exe 3. Common Errors & Root Causes
Failures associated with this process often manifest as the following error codes: Error Code Common Cause The file PSMInitSession
No process found for image [PSMInitSession.exe]. Often caused by AppLocker blocking the executable or RemoteApp misconfiguration.
General failure handling the session, frequently linked to environment path errors. "System cannot find file"
Incorrect installation paths (e.g., installed on D: but registry points to C:). 4. Technical Troubleshooting & Fixes
If PSMInitSession.exe fails to launch, administrators should verify the following areas: A. AppLocker Configuration
CyberArk's hardening scripts use AppLocker to restrict unauthorized software. If these rules are outdated or misconfigured, the executable will be blocked.
Executable Files: .exe files are executable files that can run programs or scripts on a computer. They contain machine code that the computer's processor can execute directly.

PSMInitSession.exe is a critical binary component of the CyberArk Privileged Session Manager (PSM). It acts as the initialization process that bridges a user’s initial Remote Desktop (RDP) connection to the secure CyberArk environment. Core Function & Location
Purpose: It is configured to run automatically when the PSMConnect or PSMAdminConnect users log onto the PSM server. Its primary job is to kick off the specialized session environment before the actual target application (like a browser or database tool) is launched.
Default Path: Usually located at C:\Program Files (x86)\CyberArk\PSM\Components\PSMInitSession.exe. Operational Requirements To function correctly, the following must be in place:
Environment Tab Settings: For PSM users (local or domain), the "Start the following program at logon" option in their Windows profile must point to the PSMInitSession.exe path.
Permissions: The PSMConnect and PSMAdminConnect users require Read & Execute permissions on the executable and its parent folder. Executable Files :
RemoteApp Support: It is often published as a RemoteApp in RDS collections to allow seamless session window integration. Common Issues & Troubleshooting
Failure of this process typically results in the error: "The system cannot find the file specified" or "This initial program cannot be started". PSMSC036E No Process was found for image - CyberArk
In the world of high-stakes cybersecurity, PSMInitSession.exe is a critical, yet often unseen, gatekeeper. Operating deep within the CyberArk Privilege Session Manager (PSM), this executable acts as the "ignition switch" for secure remote sessions.
Here are a few things that make this small file interesting to IT pros and security enthusiasts: The Secret Handshake
When a user tries to connect to a sensitive server, the PSM server doesn't just open a door; it looks for PSMInitSession.exe to launch automatically within that specific session. If this process isn't found within a strict timeframe (governed by the InitSessionTimeout setting), the entire connection is instantly killed to prevent unauthorized access. The "AppLocker" Battleground
It is frequently at the center of a tug-of-war between security and functionality. Because it lives in the \PSM\Components folder, administrators must carefully whitelist it in Windows AppLocker. Even a standard Microsoft update (like KB5014738) can accidentally break these rules, causing "No Process Found" errors that lock admins out of their own systems. A Target for Antivirus
Because it behaves like a remote management tool, over-eager antivirus software sometimes flags it as a threat. It requires a delicate balance of permissions—specifically for groups like PSMConnect and PSMShadowUsers—to ensure it has the rights to execute without opening security holes. Common "Drama" in the Logs
If you're digging through system logs, you'll likely see its name tied to two famous error codes:
PSMSR156E: Usually means the process timed out before it could start.
PSMSC036E: Often signals a permissions or AppLocker block preventing the file from running at all.
