Inbound connection restrictions in Windows XP
symptom
On the computer running Windows XP, when you try to connect to another Windows XP computer, you may receive the following error message:
NO more Connections Can Be Made to this Remote Computer At this Time Because Theore ALREADY AS MANY Connections As The Computer CAN Accept.
the reason
This problem occurs if the computer has reached the maximum number of inbound connections that can be loaded. For Windows XP Professional, up to 10 different computers are allowed to be connected to the network. This limitation includes a combination of resources for all transmission and sharing protocols. For Windows XP Home Edition, up to 5 other computers are allowed to connect to the network. This limitation is the number of parallel sessions from other computers to be carried by the system. This limitation is not suitable for connecting to the remote computer using the management tool. Note that this limitation is only available to inbound connections to Windows XP. When using Windows XP, unlimited number of outbound connections to other systems can be established.
More information
Any file, print, named pipe, or mail slot session without any activities, automatically disconnects after the Autodisconnect time expires, and the default value of AutodisConnect time is 15 minutes. After the session is disconnected, one of 10 connections will become available, so other users can connect to the Windows XP system. Therefore, shortening AutodisConnect time can help reduce some issues that users may encounter on systems that do not use a large number of servers, with 10 or five connection restrictions. You can configure AutodisConnect time by running the following command at the command prompt:
NET Config Server / Autodisconnect: Time before the connection is automatically disconnected
Specified time (in minutes). The Windows Server service is self-optimized, and server configuration parameters are usually automatically configured (calculates and settings) each time you start Windows XP. If you run "Net Config Server" in conjunction with / autodisconnect, / servcomment, or / hidden option, the current value of the automatically optimized parameter is displayed, and these values will be written to the registry. After these parameters are written to the registry, you will not be able to use the "Network" tool in Control Panel to adjust the server service. If you change any settings for the server service, Windows XP will not be able to automate server services for your new configuration. To avoid the automatic self-optimization feature of the server service, make changes to the "network" from the command line or "Control Panel" by the Registry Editor. All logical drives from a single computer, logical printers, and transmission level connections are considered a session; therefore, these connections are only one connection in 10 connection limits. For example, if a user is established to two logical drive connections to a Windows XP system, two Windows socket connections are connected to a logical printer, only one session is established. As a result, although three logical connections have been established, the connection to the Windows XP system has only increased. The only way system A can establish multiple sessions with another system (system z) is: System A is running a logical connection to the system z. For example, if a user logs in to system A, a service is running under the USER1 account on system A, and the user and service (as user1) establishes the connection to the system Z, two sessions are established. Each login session using the server service will be placed in the number of connections. According to the design of the developer: Connection restrictions refer to any file, print, named pipe, or mail slot session, for any file, print, named pipe, or mail slot session, based on the number of connections. The TCP connection restriction is not forced, but it may be subject to the legal agreement and cannot exceed 10 clients. The information in this article applies to:
