The Automatic Reconnection feature allows a client to reconnect to an existing session after a short-term network failure has occurred without having to resend the user's credentials to the server.
A connection which employs Automatic Reconnection proceeds as follows:. The user logs in to a new or existing session. As soon as the user has been authenticated, a Server Auto-Reconnect Packet section 2. The Auto-Reconnect Packet also called the auto-reconnect cookie contains a byte cryptographically secure random number called the auto-reconnect random and the ID of the session to which the user has connected.
The client receives the cookie and stores it in memory, never allowing programmatic access to it. In the case of a disconnection due to a network error, the client attempts to reconnect to the server by trying to reconnect continuously or for a predetermined number of times. Once it has connected, the client and server can exchange large random numbers the client and server random specified in section 5.
The client derives a byte security verifier from the random number contained in the auto-reconnect cookie received in Step 2. This security verifier is wrapped in a Client Auto-Reconnect Packet section 2.
In this case, for the purpose of generating the security verifier, the client random is assumed to be an array of 32 zero bytes. This implies that the derived security verifier will always have the same value for a given auto-reconnect random when auto-reconnecting with Enhanced RDP Security. When the server receives the Client Auto-Reconnect Packet, it looks up the auto-reconnect random for the session and computes the security verifier using the client random the same calculation executed by the client.
If the security verifier value which the client transmitted matches the one computed by the server, the client is granted access. At this point, the server has confirmed that the client requesting auto-reconnection was the last one connected to the session in question. If the check in Step 5 passes, then the client is automatically reconnected to the desired session; otherwise the client obtains the user's credentials to regain access to the session on the remote server.
The auto-reconnect cookie associated with a given session is flushed and regenerated whenever a client connects to the session or the session is reset. This ensures that if a different client connects to the session, then any previous clients which were connected can no longer use the auto-reconnect mechanism to connect. Furthermore, the server invalidates and updates the cookie at hourly intervals, sending the new cookie to the client in the Save Session Info PDU.

Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base: Description of the Microsoft Windows Registry. This article describes the Automatic Reconnection feature for terminal services in Windows. Server More Information. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly.
Use Registry Editor at your own risk. Windows Server includes the Automatic Reconnection feature for terminal services. You can use this feature to automatically reconnect to the same session without re-typing logon credentials if the session is disconnected because of dropped packets on the network or a network error. By default, a maximum of twenty reconnection attempts are made at five-second intervals. You can turn on the Automatic Reconnection feature in Windows Server either in the Remote Desktop Connection tool or through a group policy.
You can turn the Automatic Reconnection feature off by editing the registry. When a client loses network connectivity, Automatic Reconnection informs you that it is trying to reconnect to the broken session. The session appears in grayscale, and you receive the following reconnecting message: The connection has been lost. Attempting to reconnect you to your session. AutoReconnect Max Retries:i: number.

Users are able to RDP with network load balancing ok. However, users tends to just disconnect their session and when they reconnect, they do not get their existing disconnected session. Therefore they have 2 Sessions at the 2 RDS servers.
If you specify "Never," the user's disconnected session is maintained for an unlimited time. When a session is in a disconnected state, running programs are kept active even though the user is no longer actively connected.
Specify the maximum amount of time that the user's Remote Desktop Services session can be active before the session is automatically disconnected or ended. The user receives a warning two minutes before the Remote Desktop Services session is disconnected or ended, which allows the user to save open files and close programs. Specify the maximum amount of time that an active Remote Desktop Services session can be idle without user input before the session is automatically disconnected or ended.
The user receives a warning two minutes before the session is disconnected or ended, which allows the user to press a key or move the mouse to keep the session active. Specify whether to disconnect or end the user's Remote Desktop Services session when an active session limit or an idle session limit is reached. If the user's session is disconnected, the programs that the user is running are kept active even though the user is no longer actively connected.
Changes to timeout and reconnection settings are not applied to sessions that are connected when the change is made. You can also configure timeout and reconnection settings by applying the following Group Policy settings:. I will try this out however Im unsure if this is related to the issue I am encountering. I disconnected the sessions. Then I reconnect again to check if I will reconnect to the same disconnected session with opened applications. However, upon reconnecting, some of those accounts got reconnected to the same session however some does not.
I checked on the sessions, some of the accounts have new active connection to RDS1 and 1 disconnected session on RDS2. That's due to the load balancing I'm assuming. If you apply the suggested policy above and ensure that it applies to all of these users, that should take care of the issue.
You also have to remember that if you created the policy, GPO's can take up to 90 minutes to replicate throughout your network, so maybe some of those accounts aren't updated with the changes yet. Is there a resolution on this problem? I opened up a support ticket from microsoft and its been a week now and still no resolution.

As part of the logon process, the files are cached in a local folder and no deployment is therefore needed.
You only need to activate it in the Logon Script Builder, which looks like this: Rerun the logon script In the simplest form, click the first option "Rerun logon script at session reconnect" to rerun the full logon script on session reconnect.
What this does, is that whenever the user resumes a session that is already running, the full logon script executes again. The only difference to the "normal" logon script is that the big splash screen is not shown, as this is would be annoying to the end user.
The big advantage of rerunning the logon script is that printers will be adjusted to reflect the new location of the client running the remote session.New: Fix Internet - Connecting and Disconnecting Problem - (Solved)
Remote desktop rebooting
Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up. I often find myself connecting to a workstation or server with Remote Desktop to perform a task which requires a reboot. In these cases, I usually need to reconnect after the host comes back online to ensure everything went as planned or to continue my work.
In these cases, I will typically launch "ping -t" in a command prompt to let me know when I can reconnect. However, I will occasionally get distracted with something else while waiting for the host to come back online and forget to come back to it. It would be really nice to be alerted when the host is back online and allow me to reconnect ideally with a single click. Does anyone know of an easy way to accomplish this? I'm thinking there must be a free utility available, or perhaps it could be done with a PowerShell script.
Quick and dirty Powershell script that I use daily:. Doesn't time out, I'm afraid. But that could be easily added, along with a quick beep on successful response. The bit I'm more happy with taken from a currently unremembered source on the internet is that this won't try and connect when the server comes responds to ping - instead, only when the standard RDP port is accessible. This piece waits for the Server to come back online.
It could be not so difficult to achieve what you want with this two script. OK, I don't know of anything that will call your cell phone, but if you open a command box, and do "ping -t" minus the quotes, it will keep pinging It is hard to ignore that in the middle of your screen when you get back.
In the alternative, I strongly suggest you use choline daily as your mind is frying at a relatively young age. I have a simple script on each of my servers that emails me when the server has rebooted. It's a batch file using blat on Windows, perl scripts on Mac and Linux. They are triggered by whatever means is appropriate to the OS.I'm running into some sort of security issue. Some of our customers actively lock their RDP session so obviously no-one can use it.
It seems that when you lock your RDP session, and then get a reconnect to the server, and the RDP client reconnects, it automatically logs you in again, circumventing the lock.
Easy to abuse too: locked session? Now some of this is prevented as we have some customers that have 2FA implemented on the RD Gateways, so when the session reconnects, you'll need to approve the 2FA. But not all customers have that. Please remember to mark the replies as answers if they help. If you have feedback for TechNet Subscriber Support, contact tnmff microsoft. You can do this via group policy setting:.
Once users log back on automatic reconnects will be disabled. Well, that's not a real fix.
Automatically force log off and terminate disconnected RDP sessions to free up system resources.
I guess there should be a mechanism in place, if a user is actually working in his session and it gets disconnected, the reconnect should 'log in'. However, when the session was already locked, it shouldn't unlock. Disabling reconnecting altogether wouldn't be really userfriendly, given that all our users are on WAN. We've got quite stable connections for most of them, but still, reconnects occur over time. I actually think this is quite a security breach.
Settings screensaver to 60 seconds what?! I'll keep on looking. That's true, it's a workaround that you can choose or not based on what is a higher priority. It's not my preference, but like or it not this has been the way it behaves for a long time. Have you opened a support case with Microsoft? It is possible they will consider this a security issue and develop a hotfix to change it. There are additional ways you can look at this from a security perspective.
