We used to have a problem that people leave their RDP sessions open indefinitely, preventing other people from accessing the server when 2 sessions are in use. Friday, February 13, AM. Hi, Thank you for your update. Based on my research, you may refer to the following steps to achieve your goal: Using Terminal Services Configuration 1. Wednesday, February 18, AM. Hi, According to your description, I understand that you have two questions: 1.
Monday, February 16, AM. You must have misunderstood my original posting - or maybe I am asking the wrong question; I said: We fixed this by setting a Group Policy config This works, So for your question 1 - the answer is no, the computers get the Group Policy applied and it works.
GP Result shows that we get the GPO applied and the settings in the registry key that you pointed me to are exactly as specified in the GPO - on both and servers.
We have no problems with the setting being applied to Windows servers. And for your second question, the answer is also no. Look very carefully at the link that you sent me about RDC 6.
Then later in the article; Windows Server session 0 is a noninteractive session that is reserved for services. Thanks for that, it has helped. But, that raises a new question. So my new question is; How do I temporarily bypass Terminal Services restrictions that are in place through Group Policy so that I can leave a session running on a server without it being timed out as "idle" when it is an application doing a process that needs to run as an interactive session in our case; monitoring systems, Exchange mailbox moves happening in the middle of the night, legacy applications that can't run as a service etc.
Monday, February 16, PM. Nevertheless I have added some detail - the connection would have timed out after 2 hours. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name. Email Required, but never shown.

Establishing numerous null sessions will cause the server to slow down or possibly fail. A malicious user might repeatedly establish SMB sessions until the server stops responding; at this point, SMB services will become slow or unresponsive.
The Microsoft network server: Amount of idle time required before suspending session policy setting determines the amount of continuous idle time that must pass in an SMB session before the session is suspended due to inactivity. You can use this policy setting to control when a device suspends an inactive SMB session. The session is automatically reestablished when client device activity resumes.
For this policy setting, a value of 0 means to disconnect an idle session as quickly as is reasonably possible. If no acknowledgment has been received for the data in a given segment before the timer expires, the segment is retransmitted, up to the TcpMaxDataRetransmissions value.
The default value for this parameter is 5. The retransmission timer is initialized to three seconds when a TCP connection is established. The timer for a given segment is doubled after each retransmission of that segment. By using this algorithm, TCP tunes itself to the normal delay of a connection. TCP connections that are made over high-delay links take much longer to time out than those that are made over low-delay links.
By default, after the retransmission timer hits seconds, it uses that value for retransmission of any segment that has to be retransmitted. This can cause long delays for a client to time-out on a slow link.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly.
Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
