S1 Agent Download: How to Use SentinelCtl.exe Command Line Tool to Manage SentinelOne Agents on Windows Devices

If you have automatic updating turned on, the latest version of the Windows Update Agent is downloaded and installed automatically on your computer. Or, you can manually download and install the Windows Update Agent.

download s1 agent


Windows Update helps keep your computer up-to-date and secure by downloading and installing the latest security and other updates from Microsoft. Windows Update determines which updates apply to your computer.

After you turn on Windows Update, the required updates to components of Windows Update will be downloaded and installed automatically without notifying you. This behavior occurs regardless of which setting you use to turn on Windows Update. If you do not want to receive required updates, you can disable automatic updates in Control Panel.

The updates to Windows Update itself typically do the following: Address feedback from customers, improve compatibility, service performance and reliability, and enable new service capabilities. When the Windows Update server is updated, a corresponding client update is typically required. During an agent self-update operation, Windows Update Agent files may be added, modified, or replaced. For example, Windows Update Agent files that help display the user experience or that determine whether updates apply to a particular system may be added. This behavior occurs when a system is set to automatically check for available updates. This does not occur when automatic updates are turned off. For example, this behavior does not occur if you select Never check for updates in Windows Vista and Windows 7 or if you select Turn off Automatic Updates in Windows XP.

During installation and runtime, the agent needs connectivity to Azure AD Connect Health service endpoints. If firewalls block outbound connectivity, make sure that the URLs in the following table aren't blocked by default.

To verify that the agent was installed, look for the following services on the server. If you completed the configuration, they should already be running. Otherwise, they're stopped until the configuration is complete.

The Usage Analytics feature needs to gather and analyze data, so the Azure AD Connect Health agent needs the information in the AD FS audit logs. These logs aren't enabled by default. Use the following procedures to enable AD FS auditing and to locate the AD FS audit logs on your AD FS servers.

The Azure AD Connect Health agent for sync is installed automatically in the latest version of Azure AD Connect. To use Azure AD Connect for sync, download the latest version of Azure AD Connect and install it.

To verify that the agent has been installed, look for the following services on the server. If you completed the configuration, the services should already be running. Otherwise, the services are stopped until the configuration is complete.

Manually register the Azure AD Connect Health agent for sync by using the following PowerShell command. The Azure AD Connect Health services will start after the agent has been successfully registered.

At this point, the services should be started automatically, allowing the agent to monitor and gather data. If you haven't met all the prerequisites outlined in the previous sections, warnings appear in the PowerShell window. Be sure to complete the requirements before you install the agent. The following screenshot shows an example of these warnings.

After you install the relevant agent setup.exe file, you can register the agent by using the following PowerShell commands, depending on the role. Open PowerShell as administrator and run the relevant command:

You can import Internet Explorer HTTP proxy settings so that Azure AD Connect Health agents can use the settings. On each of the servers that run the health agent, run the following PowerShell command:

Occasionally, the Azure AD Connect Health agent loses connectivity with the Azure AD Connect Health service. Causes of this connectivity loss might include network problems, permissions problems, and various other problems.

To use the connectivity tool, you must first register the agent. If you can't complete the agent registration, make sure that you meet all the requirements for Azure AD Connect Health. Connectivity is tested by default during agent registration.

I'm approaching one full year of having SentinelOne and I've been thoroughly impressed with it. There's a terrific amount of detail about detected threats, a terrific amount of control you can have over endpoints, and one of my favorite features is the ability to disconnect any endpoint from all internet access EXCEPT it's own communication with the SentinelOne portal. On some cases where it threw a red flag and I wasn't immediately sure if it was a legit threat or not, I was able to disconnect it from the network in the portal giving me time to get hands on with the machine, and you can still issue cleanup commands from the S1 portal as the agent is still able to phone home under these conditions. Once I've verified that it is either A) clean, or B) false positive, I can reconnect it to the network. Has taken a lot of the worry out of the investigation process for me. As with anything, your mileage may vary. It's not bad to listen to and read accounts of folks who had a negative experience, but I think those of us who've had positive ones should balance it as well so those seeking info on a product can make their own judgments. Does any other anti-malware company offer $1 Million in ransomware insurance as part of the product?

SOLUTION PROVIDED Richard Amatorio 07/08/20 Hi Rob, Thank you for your time. I do apologize if the chat session got disconnected suddenly. As discussed earlier, You want to uninstall SentinelOne agent from all the devices on your test machines.Please follow the steps below on how to obtain the Passphrase (also know as verification key) to do CLI uninstall on a device.1. In the Management Console, click Sentinels.2. In the Sentinels view, search for the endpoint.3. Click the endpoint to open its details.4. In the Details window, click Actions and select Show passphrase.5. The Passphrase opens in a new window. Copy it to a file to use as needed.I have attached the updated "" on this email. Please see the below procedure on how to run the "SentinelCleaner" on safe mode. 1. Download the SentinelCleaner and save it to the C drive. Password to open the zip : solarwinds 2. Reboot the machine into Safe Mode (MANDATORY) 3. Run the cleaner in Safe Mode (MANDATORY), from C drive (Same folder you have extracted the file) 4. Verify cleaned correctly. a. Run regedit. b. Verify that all the 'sentinel' registry keys are removed. Search for the string 'sentinel'. If it is present, remove the outstanding keys manually. Note: If the deletion is not possible, change the ownership of those registry keys to the current admin c. Verify that the "Sentinel" Program folder, its sub-directories, and the hidden Sentinel ProgramData folder are removed. Reminder: To see the hidden ProgramData folders, change the folder view options to show hidden items. 5. When the system reboots twice, it is ready for fresh agent installation. I have also attached screenshots of the things you need to check in the registry. In addition, on the images, there are items that can't be scrolled to the right, that is why I have added them below. This is under "Solution B" of the "The batch file contains the following".SUBINACL /subkeyreg "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SentinelAgent" /setowner=administratorsSUBINACL /subkeyreg "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SentinelAgent" /grant=administrators=fSUBINACL /subkeyreg "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SentinelAgent" /grant="CREATOR OWNER"=fSUBINACL /subkeyreg "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SentinelMonitor" /setowner=administratorsSUBINACL /subkeyreg "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SentinelMonitor" /grant=administrators=fSUBINACL /subkeyreg "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SentinelMonitor" /grant="CREATOR OWNER"=freg delete HKLM\SYSTEM\CurrentControlSet\services\SentinelAgent /freg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SentinelMonitor /fPlease let us know if you need further assistance.

They are VERY careful in giving out the cleaner utility, for obvious reasons. Even if you could find somewhere to download it would likely be out of date as they update it often. Your best bet is to talk to your distributor or to SentinelOne themselves and you can get it from them.

Don't know why you're getting so much shade for dissing S1. When it works, it works. When it doesn't, it's a huge time sink. No, we didn't read anything wrong. We had endpoints running S1 agents and out of the blue after a routine update to the s1 agent they dropped off our controller. No way to uninstall except using the cleaner, which works only about 75% of the time. Terrible and I wish we'd have gone with something else.

Natively, it cannot. You would need a third-party deployment agent to deploy. But Ranger Pro (which is a add-on option) does have the ability to not only push out the S1 agent to PCs, it can do so automatically when a new PC comes online.

Very old post, I know. I wanted to note for sake of this thread that much has improved since the time you mention. I've been running SentinelOne for 1.5-2 years now, and massive changes have taken place. The agent doesn't break anywhere near as easily, and I've had to use the cleaner tool a fraction of the time from back when I started. The version changes have taken this from a halfway-decent solution to a very good solution.
