If you encounter an "Access Denied" error when using the runas command on Windows Server 2022, it could be due to several reasons. Here are some troubleshooting steps you can try:

  1. Check User Account Control (UAC) Settings: Ensure that the UAC settings on the server allow the use of the runas command. UAC may restrict certain actions, including running applications as a different user. Adjust the UAC settings if necessary.

  2. Verify User Permissions: Make sure the user account you are using to execute the runas command has the necessary permissions to run applications as a different user. Check if the user is a member of the Administrators group or has appropriate privileges.

  3. Run Command Prompt as Administrator: Launch the Command Prompt or PowerShell session as an administrator before executing the runas command. Right-click on the Command Prompt or PowerShell shortcut and select "Run as administrator." This ensures that you have elevated privileges to execute the runas command.

  4. Use Local Administrator Account: Try using the local administrator account on the server to execute the runas command. This account often has the necessary permissions and avoids any issues with domain-based user accounts.

  5. Check Group Policy Settings: Verify if any Group Policy settings or security policies on the server are restricting the usage of the runas command. Consult your system administrator or review the Group Policy settings to ensure there are no restrictions in place.

  6. Temporarily Disable Antivirus or Security Software: Temporarily disable any antivirus or security software on the server to check if they are interfering with the runas command. Some security software may block or restrict the execution of certain commands.

If none of the above steps resolve the "Access Denied" error, it's recommended to consult your system administrator or IT support for further assistance. They can help analyze the specific server configuration and security settings to determine the root cause of the issue and provide appropriate solutions.

Please exercise caution when making changes to system configurations and ensure that you have the necessary permissions and authorization to modify server settings.
