What is Connection (in computer networking)?

A link between two computers for the purpose of exchanging information. An example would be a Microsoft Windows NT Workstation, Windows 95, or Windows 98 client computer accessing a shared folder or printer on a Windows 2000 server. The term «connection» is also used to describe the establishment of communication over a WAN link, as in using a dial-up connection over a modem.


When a client computer tries to connect to a server, the success or failure of the attempt can depend upon whether

  • The server has shared the resource that the client wants to connect to
  • The client has been properly authenticated or has permission to access the resource
  • The client is properly licensed to connect to the server, and free licenses are available

When a Windows NT Workstation client receives the message “No more connections can be made at this remote computer at this time because there are already as many connections as the computer can accept,” or a Windows 95 or Windows 98 client receives the message “This request is not accepted by the network, try again later,” it means the client is being denied a connection to the Windows NT server. Possible reasons might include the following:

  • The User Limit setting (on the Sharing tab of the folder’s property sheet) has been exceeded.
  • Your network uses Per Server licensing, and all licenses are currently allocated to connected users.
